UNIX-like OS (Linux, HP/UX, Mac OSX, etc.) : Many distributions of Linux/Unix come with some of the dependencies below pre-installed or easily installed via updates. You should consult your particular distribution's documentation or local system administrators to determine what is already available.
Microsoft Windows: After verifying all prerequisites below, see the Windows Installation section for Windows tailored instructions

Java JDK 7 or 8 (OpenJDK or Oracle JDK)

Note

title	OpenJDK 8 is highly recommended

DSpace 6.x is untested on Java 11 or above. While some functionality may work fine, some DSpace 6.x dependencies cannot be updated to full Java 11 support (see DS-4348 (#7687)). Full Java 11 support will arrive in DSpace 7.

Therefore, for DSpace 6.x we recommend using OpenJDK 8, which is under support until at least May 2026.

OpenJDK download and installation instructions can be found here http://openjdk.java.net/install/. Most operating systems provide an easy path to install OpenJDK. Just be sure to install the full JDK (development kit), and not the JRE (which is often the default example).

...

You can configure a proxy to use for some or all of your HTTP requests in Maven. The username and password are only required if your proxy requires basic authentication (note that later releases may support storing your passwords in a secured keystore‚ in the mean time, please ensure your settings.xml file (usually ${user.home}/.m2/settings.xml) is secured with permissions appropriate for your operating system).

Example:

Code Block

language	xml

<settings>
  .
  .
  <proxies>
   <proxy>
      <active>true</active>
      <protocol>http</protocol>
      <host>proxy.somewhere.com</host>
      <port>8080</port>
      <username>proxyuser</username>
      <password>somepassword</password>
      <nonProxyHosts>www.google.com|*.somewhere.com</nonProxyHosts>
    </proxy>
  </proxies>
  .
  .
</settings>

...

PostgreSQL can be downloaded from http://www.postgresql.org/. It is also provided via many operating system package managers
- If the version of Postgres provided by your package manager is outdated, you may wish to use one of the official PostgreSQL provided repositories:
  - Linux users can select their OS of choice for detailed instructions on using the official PostgreSQL apt or yum repository: http://www.postgresql.org/download/linux/
  - Windows users will need to use the windows installer: http://www.postgresql.org/download/windows/
  - Mac OSX users can choose their preferred installation method: http://www.postgresql.org/download/macosx/
Install the pgcrypto extension. It will also need to be enabled on your DSpace Database (see Installation instructions below for more info).
- On most Linux operating systems (Ubuntu, Debian, RedHat), this extension is provided in the "postgresql-contrib" package in your package manager. So, ensure you've installed "postgresql-contrib".
- On Windows, this extension should be provided automatically by the installer (check your "[PostgreSQL]/share/extension" folder for files starting with "pgcrypto")
Unicode (specifically UTF-8) support must be enabled (but this is enabled by default).
Once installed, you need to enable TCP/IP connections (DSpace uses JDBC):
- In postgresql.conf: uncomment the line starting: listen_addresses = 'localhost'. This is the default, in recent PostgreSQL releases, but you should at least check it.
- Then tighten up security a bit by editing pg_hba.conf and adding this line:
  Code Block
  language text
  host dspace dspace 127.0.0.1 255.255.255.255 md5
  .
  This should appear before any lines matching all databases, because the first matching rule governs.
- Then restart PostgreSQL.

...

Details on acquiring Oracle can be downloaded from the following location: http://www.oracle.com/database/. You will need to create a database for DSpace. Make sure that the character set is one of the Unicode character sets. DSpace uses UTF-8 natively, and it is suggested that the Oracle database use the same character set. You will also need to create a user account for DSpace (e.g. dspace) and ensure that it has permissions to add and remove tables in the database. Refer to the Quick Installation for more details.
- NOTE: If the database server is not on the same machine as DSpace, you must install the Oracle client to the DSpace server and point tnsnames.ora and listener.ora files to the database the Oracle server.
- For people interested in switching from PostgreSQL to Oracle (or visa versa), you may be able to inves

8, Jetty, Caucho Resin or equivalent)

Note

title	Tomcat 8 Version

Tomcat 8.0.32 (found e.g. in Debian 9 Stretch and Ubuntu 16.04 Xenial) has a bug which will cause PropertyBatchUpdateException or StringIndexOutOfBoundsException. This was fixed in 8.0.33. More information can be found in DS-3142.

Note

title	Tomcat 7 Version

If you are using Tomcat 7 , we recommend running Tomcat 7.0.30 or above. Tomcat 7.0.29 and lower versions suffer from a memory leak. As a result, those versions of tomcat require an unusual high amount of memory to run DSpace. This has been resolved as of Tomcat 7.0.30. More information can be found in DS-1553 is EOL since March 31st 2021, and has not received recent security updates. The use of Tomcat 7 is no longer advised.

Apache Tomcat 8Apache Tomcat 7 or later. Tomcat can be downloaded from the following location: http://tomcat.apache.org.

The Tomcat owner (i.e. the user that Tomcat runs as) must have read/write access to the DSpace installation directory (i.e. [dspace]). There are a few common ways this may be achieved:
- One option is to specifically give the Tomcat user (often named "tomcat") ownership of the [dspace] directories, for example:
  Code Block
  language bash
  # Change [dspace] and all subfolders to be owned by "tomcat" chown -R tomcat:tomcat [dspace]
- Another option is to have Tomcat itself run as a new user named "dspace" (see installation instructions below). Some operating systems make modifying the Tomcat "run as" user easily modifiable via an environment variable named TOMCAT_USER. This option may be more desireable desirable if you have multiple Tomcat instances running, and you do not want all of them to run under the same Tomcat owner.
You need to ensure that Tomcat has a) enough memory to run DSpace and b) uses UTF-8 as its default file encoding for international character support. So ensure in your startup scripts (etc) that the following environment variable is set: JAVA_OPTS="-Xmx512M -Xms64M -Dfile.encoding=UTF-8"

Modifications in [tomcat]/conf/server.xml : You also need to alter Tomcat's default configuration to support searching and browsing of multi-byte UTF-8 correctly. You need to add a configuration option to the <Connector> element in [tomcat]/config/server.xml: URIEncoding="UTF-8" e.g. if you're using the default Tomcat config, it should read:

Code Block

language	html/xml

<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
<Connector port="8080"
              minSpareThreads="25"
              enableLookups="false"
              redirectPort="8443"
              connectionTimeout="20000"
              disableUploadTimeout="true"
              URIEncoding="UTF-8"/>

You may change the port from 8080 by editing it in the file above, and by setting the variable CONNECTOR_PORT in server.xml. You should set the URIEncoding even if you are running Tomcat behind a proxy (Apache HTTPD, Nginx, etc.) via AJP.

Tomcat 8 and above is using at least Java 1.7 for JSP compilation. However, by default, Tomcat 7 uses Java 1.6 for JSP compilation. If you want to use Java 1.7 in your .jsp files, you have to change the configuration of Tomcat 7. Edit the file called web.xml in the configuration directory of your Tomcat instance (${CATALINA_HOME}/conf in Tomcat notation). Look for a servlet definition using the org.apache.jasper.servlet.JSPServlet servlet-class and add two init parameters compilerSourceVM and compilerTargetVM as you see it in the example below. Then restart Tomcat.

Code Block

language	xml
title	${CATALINA_BASE}/conf/web.xml

 <servlet>
        <servlet-name>jsp</servlet-name>
        <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
        <init-param>
            <param-name>fork</param-name>
            <param-value>false</param-value>
        </init-param>
        <init-param>
            <param-name>xpoweredBy</param-name>
            <param-value>false</param-value>
        </init-param>
        <init-param>
            <param-name>compilerSourceVM</param-name>
            <param-value>1.7</param-value>
        </init-param>
        <init-param>
            <param-name>compilerTargetVM</param-name>

        </init-param>
        <load-on-startup>3</load-on-startup>
    </servlet>

Jetty or Caucho Resin DSpace will also run on an equivalent servlet Engine, such as Jetty (https://www.eclipse.org/Jetty or Caucho Resin DSpace will also run on an equivalent servlet Engine, such as Jetty (https://www.eclipse.org/jetty/) or Caucho Resin (http://www.caucho.com/). Jetty and Resin are configured for correct handling of UTF-8 by default.

...

Create the DSpace user (optional) . As noted in the prerequisites above, Tomcat (or Jetty, etc) must run as an operating system user account that has full read/write access to the DSpace installation directory (i.e. [dspace]). Either you must ensure the Tomcat owner also owns [dspace], OR you can create a new "dspace" user account, and ensure that Tomcat also runs as that account:
Code Block
language bash
useradd -m dspace
Download the latest DSpace release. There are two version available with each release of DSpace: (dspace-n.x-release. and dspace-n.x-src-release.zzzzip); you only need to choose one. If you want a copy of all underlying Java source code, you should download the dspace-n.x-src-release.xxxzip. Within each version, you have a choice of compressed file format. Choose the one that best fits your environment.
1. Alternatively, you may choose to check out the latest release from the DSpace GitHub Repository. In this case, you'd be checking out the full Java source code. You'd also want to be sure to checkout the appropriate tag (e.g. dspace-6.0) or branch. For more information on using / developing from the GitHub Repository, see: Development with Git
Unpack the DSpace software. After downloading the software, based on the compression file format, choose one of the following methods to unpack your software:
1. Zip file. If you downloaded dspace-6.x-release.zip do the following:
  Code Block
  language bash
  unzip dspace-6.x-release.zip
2. .gz file. If you downloaded dspace-6.x-release.tar.gz do the following:
  Code Block
  language bash
  gunzip -c dspace-6.x-release.tar.gz | tar -xf -
3. .bz2 file. If you downloaded _dspace-6.x-release.tar.bz do the following:
  Code Block
  language bash
  bunzip2 dspace-6.x-release.tar.bz | tar -xf -
  For ease of reference, we will refer to the location of this unzipped version of the DSpace release as [dspace-source] in the remainder of these instructions. After unpacking the file, the user may wish to change the ownership of the dspace-6.x-release to the "dspace" user. (And you may need to change the group).

Database Setup

Also see "Relational Database" prerequisite notes above

PostgreSQL:

A PostgreSQL JDBC driver is configured as part of the default DSpace build. You no longer need to copy any PostgreSQL jars to get PostgreSQL installed.
Create a dspace database user (this user can have any name, but we'll assume you name them "dspace"). This is entirely separate from the dspace operating-system user created above:
Code Block
language bash
createuser --username=postgres --no-superuser --pwprompt dspace
You will be prompted (twice) for a password for the new dspace user. Then you'll be prompted for the password of the PostgreSQL superuser (postgres).
Create a dspace database, owned by the dspace PostgreSQL user. Similar to the previous step, this can only be done by a "superuser" account in PostgreSQL (e.g. postgres):
Code Block
language bash
createdb --username=postgres --owner=dspace --encoding=UNICODE dspace
You will be prompted for the password of the PostgreSQL superuser (postgres).

Finally, you MUST enable the pgcrypto extension on your new dspace database. Again, this can only be enabled by a "superuser" account (e.g. postgres)

Code Block

language	bash

# Login to the database as a superuser, and enable the pgcrypto extension on this database
psql --username=postgres dspace -c "CREATE EXTENSION pgcrypto;"

The "CREATE EXTENSION" command should return with no result if it succeeds. If it fails or throws an error, it is likely you are missing the required pgcrypto extension (see Database Prerequisites above).

Alternative method: How to enable pgcrypto via a separate database schema. While the above method of enabling pgcrypto is perfectly fine for the majority of users, there may be some scenarios where a database administrator would prefer to install extensions into a database schema that is separate from the DSpace tables. Developers also may wish to install pgcrypto into a separate schema if they plan to "clean" (recreate) their development database frequently. Keeping extensions in a separate schema from the DSpace tables will ensure developers would NOT have to continually re-enable the extension each time you run a "./dspace database clean". If you wish to install pgcrypto in a separate schema here's how to do that:

Code Block

language	sql

# Login to the database as a superuser
psql --username=postgres dspace
# Create a new schema in this database named "extensions" (or whatever you want to name it)
CREATE SCHEMA extensions;
# Enable this extension in this new schema
CREATE EXTENSION pgcrypto SCHEMA extensions;
# Grant rights to call functions in the extensions schema to your dspace user
GRANT USAGE ON SCHEMA extensions TO dspace;


# Append "extensions" on the current session's "search_path" (if it doesn't already exist in search_path)
# The "search_path" config is the list of schemas that Postgres will use
SELECT set_config('search_path',current_setting('search_path') || ',extensions',false) WHERE current_setting('search_path') !~ '(^|,)extensions(,|$)';
# Verify the current session's "search_path" and make sure it's correct
SHOW search_path;
# Now, update the "dspace" Database to use the same "search_path" (for all future sessions) as we've set for this current session (i.e. via set_config() above)
ALTER DATABASE dspace SET search_path FROM CURRENT;

Oracle:

Setting up DSpace to use Oracle is a bit different now. You will need still need to get a copy of the Oracle JDBC driver, but instead of copying it into a lib directory you will need to install it into your local Maven repository. (You'll need to download it first from this location: http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-112010-090769.html.) Run the following command (all on one line):
Code Block
language bash
mvn install:install-file -Dfile=ojdbc6.jar -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.4.0 -Dpackaging=jar -DgeneratePom=true
You need to compile DSpace with an Oracle driver (ojdbc6.jar) corresponding to your Oracle version - update the version in [dspace-source]/pom.xml E.g.:
Code Block
language html/xml
<dependency> <groupId>com.oracle</groupId> <artifactId>ojdbc6</artifactId> <version>11.2.0.4.0</version> </dependency>
Create a database for DSpace. Make sure that the character set is one of the Unicode character sets. DSpace uses UTF-8 natively, and it is required that the Oracle database use the same character set. Create a user account for DSpace (e.g. dspace) and ensure that it has permissions to add and remove tables in the database.

NOTE: You will need to ensure the proper db.* settings are specified in your local.cfg file (see next step), as the defaults for all of these settings assuming a PostgreSQL database backend.

Code Block

language	text

db.url = jdbc:oracle:thin:@host:port/SID
# e.g. db.url = jdbc:oracle:thin:@//localhost:1521/xe
# NOTE: in db.url, SID is the SID of your database defined in tnsnames.ora
# the default Oracle port is 1521
# You may also use a full SID definition, e.g.
# db.url = jdbc:oracle:thin:@(description=(address_list=(address=(protocol=TCP)(host=localhost)(port=1521)))(connect_data=(service_name=DSPACE)))

# Oracle driver and dialect
db.driver = oracle.jdbc.OracleDriver
db.dialect = org.hibernate.dialect.Oracle10gDialect

# Specify DB username, password and schema to use
db.username =
db.password =
db.schema = ${db.username}
# For Oracle, schema is equivalent to the username of your database account,
# so this may be set to ${db.username} in most scenarios

Later, during the Maven build step, don't forget to specify mvn -Ddb.name=oracle package

Initial Configuration (local.cfg): Create your own [dspace-source]/dspace/config/local.cfg configuration file (you may wish to simply copy the provided [dspace-source]/dspace/config/local.cfg.EXAMPLE). This local.cfg file can be used to store any configuration changes that you wish to make which are local to your installation (see local.cfg configuration file documentation). ANY setting may be copied into this local.cfg file from the dspace.cfg or any other *.cfg file in order to override the default setting (see note below). For the initial installation of DSpace, there are some key settings you'll likely want to override, those are provided in the [dspace-source]/dspace/config/local.cfg.EXAMPLE. (NOTE: Settings followed with an asterisk (*) are highly recommended, while all others are optional during initial installation and may be customized at a later time)

dspace.dir* - must be set to the [dspace] (installation) directory (NOTE: On Windows be sure to use forward slashes for the directory path! For example: "C:/dspace" is a valid path for Windows.)
dspace.hostname - fully-qualified domain name of web server (or "localhost" if you just want to run DSpace locally for now)
dspace.baseUrl* - complete URL of this server's DSpace home page (including port), but without any context eg. /xmlui, /oai, etc.
dspace.name - "Proper" name of your server, e.g. "My Digital Library".
solr.server* - complete URL of the Solr server. DSpace makes use of Solr for indexing purposes.
default.language - Default language for all metadata values (defaults to "en_US")
db.url* - The full JDBC URL to your database (examples are provided in the local.cfg.EXAMPLE)
db.driver* - Which database driver to use, based on whether you are using PostgreSQL or Oracle
db.dialect* - Which database dialect to use, based on whether you are using PostgreSQL or Oracle
db.username* - the database username used in the previous step.
db.password* - the database password used in the previous step.
db.schema* - the database scheme to use (examples are provided in the local.cfg.EXAMPLE)
mail.server - fully-qualified domain name of your outgoing mail server.
mail.from.address - the "From:" address to put on email sent by DSpace.
mail.feedback.recipient - mailbox for feedback mail.
mail.admin - mailbox for DSpace site administrator.
mail.alert.recipient - mailbox for server errors/alerts (not essential but very useful!)

mail.registration.notify- mailbox for emails when new users register (optional)

Info

title	Your local.cfg file can override ANY settings from other *.cfg files in DSpace

The provided local.cfg.EXAMPLE only includes a small subset of the configuration settings available with DSpace. It provides a good starting point for your own local.cfg file.

However, you should be aware that ANY configuration can now be copied into your local.cfg to override the default settings. This includes ANY of the settings/configurations in:

The primary dspace.cfg file ([dspace]/config/dspace.cfg)
Any of the module configuration files ([dspace]/config/modules/*.cfg files)

Individual settings may also be commented out or removed in your local.cfg, in order to re-enable default settings.

See the Configuration Reference section for more details.

DSpace Directory: Create the directory for the DSpace installation (i.e. [dspace]). As root (or a user with appropriate permissions), run::
code
Code Block
language bash
mkdir [dspace] chown dspace [dspace]
(Assuming the dspace UNIX username.)

Build the Installation Package: As the dspace UNIX user, generate the DSpace installation package.

Code Block

language	bash

cd [dspace-source]
mvn package

Info

title	Building with Oracle Database Support

Without any extra arguments, the DSpace installation package is initialized for PostgreSQL. If you want to use Oracle instead, you should build the DSpace installation package as follows:
mvn -Ddb.name=oracle package

Info

title	Enabling and building the Mirage 2 theme (for XMLUI)

Mirage 2 is a responsive theme for the XML User Interface, added as a new feature in DSpace 5. It has not yet replaced the Mirage 1 theme as the XMLUI default theme.
The Mirage 2 build requires git to be installed on your server. Install git before attempting the Mirage 2 build.

To enable Mirage 2, install the dependencies required for building Mirage 2; Git, Node, Bower, Grunt, Ruby and Compass. The Mirage 2 developer documentation provides detailed instructions for these installations and then add the following line to the <themes> section of [dspace-source]/dspace/config/xmlui.xconf , replacing the currently active theme:

    <theme name="Mirage 2" regex=".*" path="Mirage2/" />

It is important to do this before executing the maven build.

Mirage 2 is not yet activated in the default "mvn package" build. To include it as part of the build, run:

mvn package -Dmirage2.on=true

 regex=".*" path="Mirage2/" />

It is important to do this before executing the maven buildThe speed of this specific step of the build can be increased by installing local copies of the specific dependencies required for building Mirage 2. The Mirage 2 developer documentation provides detailed instructions for these installations. After the installation of these dependencies, you can choose to run:

    
    mvn package -Dmirage2.on=true -Dmirage2.deps.included=false

Warning: The Mirage 2 build process should NOT be run as "root". It must be run as a non-root user. For more information see: Mirage 2 Common Build Issuesa non-root user. For more information see: Mirage 2 Common Build Issues

Note: Until recently DSpace 6.3 with Mirage2 could be built without dependencies pre-installed. This build process relied on bootstrapping a local Ruby environment from torquebox.org, the domain registration for which expired some time in early 2022. The torquebox project has not been maintained for a while which means that it is not possible to build DSpace 6.3 with Mirage2 anymore without dependencies pre-installed. A solution is being developed for 6.4, see Migrate Mirage 2 build from bower and Ruby sass to npm and node-sass.

Install DSpace: As the dspace UNIX user, install DSpace to [dspace]:
Code Block
language bash
cd [dspace-source]/dspace/target/dspace-installer ant fresh_install
Info
To see a complete list of build targets, run: ant help The most likely thing to go wrong here is the test of your database connection. See the Common Problems Section below for more details.
Decide which DSpace Web Applications you want to install. DSpace comes with a variety of web applications (in [dspace]/webapps), each of which provides a different "interface" to your DSpace. Which ones you install is up to you, but there are a few that we highly recommend (see below):
1. "xmlui" = This is the XML-based User Interface (XMLUI), based on Apache Cocoon. It comes with a variety of out-of-the-box themes, including Mirage 1 (the default) and Mirage 2 (based on Bootstrap). Between the "xmlui" and "jspui", you likely only need to choose one.
2. "jspui" = This is the JSP-based User Interface (JSPUI), which is based on Bootstrap. Between the "xmlui" and "jspui", you likely only need to choose one.
3. "solr" (required) = This is Apache Solr web application, which is used by the "xmlui" and "jspui" (for search & browse functionality), as well as the OAI-PMH interface. It must be installed in support of either UI.
4. "oai" = This is the DSpace OAI interface. It allows for Metadata and Bitstream (content-file) harvesting, supporting OAI-PMH (Protocol for Metadata Harvest) and OAI-ORE (Object Reuse and Exchange) protocols
5. "rdf" = This is the DSpace RDF interface supporting Linked (Open) Data.
6. "rest" = This is the DSpace REST API
7. "sword" = This is the DSpace SWORDv1 interface. More info on SWORD protocol and its usage.
8. "swordv2" = This is the DSpace SWORDv2 interface. More info on SWORD protocol and its usage.

Deploy Web Applications:

Anchor

	deployment

Please note that in the first instance you should refer to the appropriate documentation for your Web Server of choice. The following instructions are meant as a handy guide. You have two choices or techniques for having Tomcat/Jetty/Resin serve up your web applications:

Technique A. Tell your Tomcat/Jetty/Resin installation where to find your DSpace web application(s). As an example, in the directory [tomcat]/conf/Catalina/localhost you could add files similar to the following (but replace [dspace]with your installation location):

Code Block

language	html/xml
title	DEFINE A CONTEXT FOR DSpace XML User Interface: xmlui.xml

<?xml version='1.0'?>
<Context
	docBase="[dspace]/webapps/xmlui"
	reloadable="true"
	cachingAllowed="false"/>

Code Block

language	html/xml
title	DEFINE A CONTEXT PATH FOR DSpace JSP User Interface: jspui.xml

<?xml version='1.0'?>
<Context
	docBase="[dspace]/webapps/jspui"
	reloadable="true"
	cachingAllowed="false"/>

Code Block

language	xml
title	DEFINE A CONTEXT PATH FOR DSpace Solr index: solr.xml

<?xml version='1.0'?>
<Context
	docBase="[dspace]/webapps/solr"
	reloadable="true"
	cachingAllowed="false"/>

Code Block

language	html/xml
title	DEFINE A CONTEXT PATH FOR DSpace OAI User Interface: oai.xml

<?xml version='1.0'?>
<Context
	docBase="[dspace]/webapps/oai"
	reloadable="true"
	cachingAllowed="false"/>

Code Block

language	xml
title	DEFINE ADDITIONAL CONTEXT PATHS FOR OTHER DSPACE WEB APPLICATIONS (REST, SWORD, RDF, etc.): \[app\].xml

<?xml version='1.0'?>
<!-- CHANGE THE VALUE OF "[app]" FOR EACH APPLICATION YOU WISH TO ADD -->
<Context
	docBase="[dspace]/webapps/[app]"
	reloadable="true"
	cachingAllowed="false"/>

The name of the file (not including the suffix ".xml") will be the name of the context, so for example xmlui.xml defines the context at http://host:8080/xmlui. To define the root context (http://host:8080/), name that context's file ROOT.xml.

Note

title	Tomcat Context Settings in Production

The above Tomcat Context Settings show adding the following to each <Context> element:

reloadable="true" cachingAllowed="false"

These settings are extremely useful to have when you are first getting started with DSpace, as they let you tweak the DSpace XMLUI (XSLTs or CSS) or JSPUI (JSPs) and see your changes get automatically reloaded by Tomcat (without having to restart Tomcat). However, it is worth noting that the Apache Tomcat documentation recommends Production sites leave the default values in place (reloadable="false" cachingAllowed="true"), as allowing Tomcat to automatically reload all changes may result in "significant runtime overhead".

It is entirely up to you whether to keep these Tomcat settings in place. We just recommend beginning with them, so that you can more easily customize your site without having to require a Tomcat restart. Smaller DSpace sites may not notice any performance issues with keeping these settings in place in Production. Larger DSpace sites may wish to ensure that Tomcat performance is more streamlined.

Technique B. Simple and complete. You copy only (or all) of the DSpace Web application(s) you wish to use from the [dspace]/webapps directory to the appropriate directory in your Tomcat/Jetty/Resin installation. For example:
cp -R [dspace]/webapps/* [tomcat]/webapps* (This will copy all the web applications to Tomcat).
cp -R [dspace]/webapps/jspui [tomcat]/webapps* (This will copy only the jspui web application to Tomcat.)
To define the root context (http://host:8080/), name that context's directory ROOT.

Administrator Account: Create an initial administrator account from the command line:
Code Block

The following sections show how to set up the most commonly-used Java Servlet containers to support HTTP over SSL. There are two options listed:

You may choose to either enable HTTPS support in Tomcat itself (running on ports 8080 and 8443), or
You can install Apache HTTPD in front of Tomcat to run DSpace on ports 80 and 443 (this is configuration is typical when you want to run the Shibboleth SP - mod_shib with Apache HTTPD)

Enabling the HTTPS support in Tomcat itself (running on ports 8080 and 8443)

...

For Production use: Follow this procedure to set up SSL on your server. Using a "real" server certificate ensures your users' browsers will accept it without complaints. In the examples below, $CATALINA_BASE is the directory under which your Tomcat is installed.

Create a Java keystore for your server with the password changeit, and install your server certificate under the alias "tomcat". This assumes the certificate was put in the file server.pem:
Code Block
language bash
$JAVA_HOME/bin/keytool -import -noprompt -v -storepass changeit -keystore $CATALINA_BASE/conf/keystore -alias tomcat -file myserver.pem
Install the CA (Certifying Authority) certificate for the CA that granted your server cert, if necessary. This assumes the server CA certificate is in ca.pem:
Code Block
language bash
$JAVA_HOME/bin/keytool -import -noprompt -storepass changeit -trustcacerts -keystore $CATALINA_BASE/conf/keystore -alias ServerCA -file ca.pem
Optional – ONLY if you need to accept client certificates for the X.509 certificate stackable authentication module See the configuration section for instructions on enabling the X.509 authentication method. Load the keystore with the CA (certifying authority) certificates for the authorities of any clients whose certificates you wish to accept. For example, assuming the client CA certificate is in client1.pem:
Code Block
language bash
$JAVA_HOME/bin/keytool -import -noprompt -storepass changeit -trustcacerts -keystore $CATALINA_BASE/conf/keystore -alias client1 -file client1.pem

Now add another Connector tag to your server.xml Tomcat configuration file, like the example below. The parts affecting or specific to SSL are shown in bold. (You may wish to change some details such as the port, pathnames, and keystore password)

Code Block

language	html/xml

<Connector port="8443"
              URIEncoding="UTF-8"
              minSpareThreads="25"
              enableLookups="false"
              disableUploadTimeout="true"
              scheme="https" secure="true" sslProtocol="TLS"
              keystoreFile="conf/keystore" keystorePass="changeit"
              clientAuth="true" - ONLY if using client X.509 certs for authentication!
              truststoreFile="conf/keystore" truststorePass="changeit" />

Also, check that the default Connector is set up to redirect "secure" requests to the same port as your SSL connector, e.g.:

Code Block

language	html/xml

<Connector port="8080"
              minSpareThreads="25"
              enableLookups="false"
              redirectPort="8443" />

Quick-and-dirty Procedure for Testing: If you are just setting up a DSpace server for testing, or to experiment with HTTPS, then you don't need to get a real server certificate. You can create a "self-signed" certificate for testing; web browsers will issue warnings before accepting it, but they will function exactly the same after that as with a "real" certificate. In the examples below, $CATALINA_BASE is the directory under which your Tomcat is installed.

Create a new key pair under the alias name "tomcat". When generating your key, give the Distinguished Name fields the appropriate values for your server and institution. CN should be the fully-qualified domain name of your server host. Here is an example:

code

Code Block

language

bash

$JAVA_HOME/bin/keytool -genkey \
  -alias tomcat \
  -keyalg RSA \
  -keysize 1024 \
  -keystore $CATALINA_BASE/conf/keystore \
  -storepass changeit \
  -validity 365 \
  -dname 'CN=dspace.myuni.edu, OU=MIT Libraries, O=Massachusetts Institute of Technology, L=Cambridge, S=MA, C=US'

You should be prompted for a password to protect the private key.

Since you now have a signed server certificate in your keystore you can, obviously, skip the next steps of installing a signed server certificate and the server CA's certificate.

Optional – ONLY if you need to accept client certificates for the X.509 certificate stackable authentication module See the configuration section for instructions on enabling the X.509 authentication method. Load the keystore with the CA (certifying authority) certificates for the authorities of any clients whose certificates you wish to accept. For example, assuming the client CA certificate is in client1.pem:
Code Block
language bash
$JAVA_HOME/bin/keytool -import -noprompt -storepass changeit \ -trustcacerts -keystore $CATALINA_BASE/conf/keystore -alias client1 \ -file client1.pem
Follow the procedure in the section above to add another Connector tag, for the HTTPS port, to your server.xml file.

...

Install Apache HTTP Server alongside your Tomcat instance
In your Tomcat's server.xml, ensure that the AJP Connector is UNCOMMENTED. Usually this runs on port 8009, but you can decide to change the port if you desire
Code Block
language xml
 <Connector port="8009" protocol="AJP/1.3" />

Choose how you'd like to redirect requests from Apache HTTP Server to Tomcat. There are two primary options (mod_proxy OR mod_jk), just choose ONE. (NOTE: "mod_proxy" is often the easier of the two):

OPTION 1: Use "mod_proxy" and "mod_proxy_ajp" Apache modules to redirect requests to Tomcat (via AJP Connector) - RECOMMENDED

Install "mod_proxy" and "mod_proxy_ajp" (usually they are installed by default with Apache HTTP Server)
Enable both "mod_proxy" and "mod_proxy_ajp" modules. How you do this is often based on your operating system
1. In Debian / Ubuntu, there's an "a2enmod" command that enables Apache 2 modules. So, you can just run: sudo a2enmod proxy proxy_ajp
2. In other operating systems, you may need to find the appropriate "LoadModule" configurations (in Apache HTTP Server's main config) and uncomment it. You'll then need to restart Apache HTTP Server

Create a new Virtual Host in Apache HTTP Server to represent your DSpace site. Here's a basic example of a Virtual Host responding to any port 80 requests for "my.dspace.edu":

Code Block

language	xml

<VirtualHost *:80>
   # Obviously, replace the ServerName with your DSpace site URL
   ServerName my.dspace.edu

   ## Apache HTTP Server Logging Settings - modify how you see fit
   ErrorLog ${APACHE_LOG_DIR}/my.dspace.edu-error.log
   CustomLog ${APACHE_LOG_DIR}/my.dspace.edu-access.log combined

   # Possible values include: debug, info, notice, warn, error, crit, alert, emerg.
   LogLevel warn

   # There are many more configurations available for Virtual Hosts,
   # see the documentation for more details
   # http://httpd.apache.org/docs/2.4/vhosts/
</VirtualHost>

If you want your site to also respond to SSL requests, you'll need to install and enable "mod_ssl" and create a second Virtual Host to respond to port 443 requests. An example is provided below. But much more details are available in the Apache HTTP SSL Documentation and the mod_ssl documentation

Code Block

language	xml

<VirtualHost *:443>
   # Obviously, replace the ServerName with your DSpace site URL
   ServerName my.dspace.edu

   # You can have SSL Apache logging settings here too (see the port 80 example above)

   # Configure your SSL Certificate (you must create one, obviously)
   # See the "keytool" instructions above for examples of creating this certificate
   # There are also many good guides on the web for generating SSL certificates for Apache
   SSLEngine on
   SSLCertificateChainFile /path/to/your/chainfile.crt
   SSLCertificateFile      /path/to/your/public-cert.crt
   SSLCertificateKeyFile   /path/to/your/private-key.key
   
   # More information on SSL configurations can be found in the mod_ssl documentation
   # http://httpd.apache.org/docs/2.4/mod/mod_ssl.html
</VirtualHost>

Info

title	Extra SSL Configurations for X.509 Client Certificates authentication

If you are using X.509 Client Certificates for authentication: add these configuration options to the appropriate httpd configuration file, e.g. ssl.conf, and be sure they are in force for the virtual host and namespace locations dedicated to DSpace:

## SSLVerifyClient can be "optional" or "require"
SSLVerifyClient optional
SSLVerifyDepth 10
SSLCACertificateFile /path/to/your/client-CA-certificate
SSLOptions StdEnvVars ExportCertData

In each of your Apache HTTP Virtual Hosts (see above), use "ProxyPass" configurations to configure the redirects from Apache HTTP Server to Apache Tomcat. The exact configurations depend on whether you want to redirect ALL requests to Tomcat, or just certain paths. Here's a basic example. But much more information and examples can be found in the mod_proxy documentation

Code Block

language	xml

# These are just examples. THEY LIKELY WILL NEED MODIFICATION.
# Again, remember to add these to your EXISTING <VirtualHost> settings

<VirtualHost>

  ... (existing settings) ...

  # If there's a single path you do NOT want redirected, you can use ! to ignore it
  # In this case any requests to "/ignored_path" will be handled by Apache HTTPD and NOT forwarded to Tomcat
  ProxyPass  /ignored_path  !

  # These configurations say: By default, redirect ALL requests to port 8009
  # (The port MUST match the port of your Tomcat AJP Connector. By default this usually is 8009)
  ProxyPass         /  ajp://localhost:8009/
  ProxyPassReverse  /  ajp://localhost:8009/

  # You may also wish to provide additional "mod_proxy" configurations, 
  # for more examples and details see the documentation at
  # http://httpd.apache.org/docs/2.4/mod/mod_proxy.html
</VirtualHost>

OPTION 2: Alternatively, use "mod_jk" Apache module to redirect requests to Tomcat (via AJP Connector). For information on configuring mod_jk, please see the Apache Tomcat Connector documentation (specifically the "How To" on using the Tomcat Connector with Apache HTTP Server). You may also refer to our wiki guide for installing DSpace with ModJk.

Finally, restart your Apache HTTP Server and test things out.
1. If you hit any issues, it is recommended to search around for guides to running Apache HTTP Server and Apache Tomcat using either "mod_proxy" or "mod_jk". DSpace does not require any unique configurations with regards to this redirection from Apache to Tomcat. So, any guides that generally explain how to redirect requests from Apache to Tomcat should also work for DSpace.

...

You don't have to use CNRI's Handle system. At the moment, you need to change the code a little to use something else (e.g PURLs) but that should change soon.
You'll notice that while you've been playing around with a test server, DSpace has apparently been creating handles for you looking like hdl:123456789/24 and so forth. These aren't really Handles, since the global Handle system doesn't actually know about them, and lots of other DSpace test installs will have created the same IDs. They're only really Handles once you've registered a prefix with CNRI (see below) and have correctly set up the Handle server included in the DSpace distribution. This Handle server communicates with the rest of the global Handle infrastructure so that anyone that understands Handles can find the Handles your DSpace has created.
If you want to use the Handle system, you'll need to set up a Handle server. One is included with DSpace. Note that this is not required in order to evaluate DSpace; you only need one if you are running a production service. You'll need to obtain a Handle prefix from the central CNRI Handle site.

...

To configure your DSpace installation to run the handle server, run the following command:
Code Block
language bash
[dspace]/bin/dspace make-handle-config [dspace]/handle-server
Ensure that [dspace]/handle-server matches whatever you have in dspace.cfg for the handle.dir property.
1. If you are using Windows, the proper command is:
  Code Block
  language bash
  [dspace]/bin/dspace dsrun net.handle.server.SimpleSetup [dspace]/handle-server
  Ensure that [dspace]/handle-server matches whatever you have in dspace.cfg for the handle.dir property.
Edit the resulting [dspace]/handle-server/config.dct file to include the following lines in the "server_config"clause:
Code Block
language text
"storage_type" = "CUSTOM" "storage_class" = "org.dspace.handle.HandlePlugin"
This tells the Handle server to get information about individual Handles from the DSpace code.
Once the configuration file has been generated, you will need to go to http://hdl.handle.net/4263537/5014 to upload the generated sitebndl.zip file. The upload page will ask you for your contact information. An administrator will then create the naming authority/prefix on the root service (known as the Global Handle Registry), and notify you when this has been completed. You will not be able to continue the handle server installation until you receive further information concerning your naming authority.
When CNRI has sent you your naming authority prefix, you will need to edit the config.dct file. The file will be found in /[dspace]/handle-server. Look for "300:0.NA/YOUR_NAMING_AUTHORITY". Replace YOUR_NAMING_AUTHORITY with the assigned naming authority prefix sent to you. Also change the value of handle.prefix in [dspace]/config/local.cfg from "123456789" to your assigned naming authority prefix, so that DSpace will use that prefix in assigning new Handles.
Now start your handle server (as the dspace user):
Code Block
language bash
[dspace]/bin/start-handle-server
1. If you are using Windows, there is a corresponding 'start-handle-server.bat' script:
  Code Block
  language bash
  [dspace]/bin/start-handle-server.bat

...

Download the CNRI Handle Software: http://www.handle.net/download.html. In the tarball you'll find an INSTALL.txt with installation instructions -- follow it.
After installing the CNRI Handle Software you should have two directories: once that contains the CNRI software and one that contains the configuration of you local Handle Server. For the rest of this instruction we assume that the directory containing the CNRI Software is /hs/hsj-7.3.1 and the directory containing the configuration of your local server is /hs/srv_1. (We use the same paths here as CNRIs INSTALL.txt.)
Download the plugin from https://github.com/DSpace/Remote-Handle-Resolver/releases. Select a release. You can get the source and build it yourself, or just use the JAR file included in the release. In either case, once you have a dspace-remote-handle-resolver-VERSION.jar, copy it to the directory containing the CNRI software (/hs/hsj-7.3.1/lib).
Create the directory /hs/srv_1/logs.

Create the following two files in /hs/srv_1.

log4j-handle-plugin.properties

log4j.rootCategory=INFO, A1
log4j.appender.A1=org.apache.log4j.DailyRollingFileAppender
log4j.appender.A1.File=/hs/srv_1/logs/handle-plugin.log
log4j.appender.A1.DatePattern= '.' yyyy-MM-dd
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d %-5p %c @ %m%n
 log4j.logger.org.apache.axis.handlers.http.HTTPAuthHandler=INFO

Change the path in the third line, if necessary.

handle-dspace-plugin.cfg

dspace.handle.endpoint1 = http: //example.org/dspace/handleresolver

If you are using XMLUI take a look in [dspace-install]/config/dspace.cfg, change the URL above to the value of your dspace.url and add /handleresolver to the end of it. If you are using JSPUI take a look in [dspace-install]/config/dspace.cfg, change the URL above to the value of your dspace.url and add /json/hdlresolver to the end of it. If you run more than one DSpace Installation, you may add more DSpace Endpoints. Just increase the number at the end of the key for each: endpoint2, endpoint3....

Edit the file /hs/srv_1/config.dct to include the following lines in the " server_config" clause:

"storage_type" = "CUSTOM"
"storage_class" = "org.dspace.handle.MultiRemoteDSpaceRepositoryHandlePlugin"
Copy /hs/hsj-7.3.1/bin/hdl-server to /hs/srv_1/start-hdl-server.
Edit /hs/srv_1/start-hdl-server:
1. Find the last line that begins with HDLHOME=
2. Below that line add the following one: HDLHOME="/hs/hsj-7.3.1/"
3. Find a line that contains exec java ... net.handle.server.Main ...
4. Add "-Dlog4j.configuration=file:///hs/srv_1/log4j-handle-plugin.properties -Ddspace.handle.plugin.configuration=/hs/srv_1/handle-dspace-plugin.cfg" right in front of net.handle.server.Main.
If your handle server is running, stop it.
From now on you should start this handle server using /hs/srv_1/start-hdl-server

...

If you need to update the handle prefix on items created before the CNRI registration process you can run the [dspace]/bin/dspace update-handle-prefix script. You may need to do this if you loaded items prior to CNRI registration (e.g. setting up a demonstration system prior to migrating it to production). The script takes the current and new prefix as parameters. For example:

Code Block

language	bash

[dspace]/bin/dspace update-handle-prefix 123456789 1303

...

You can generate the sitemaps automatically every day using an additional cron job:

Code Block

language	bash

# Generate sitemaps at 6:00 am local time each day
0 6 * * * [dspace]/bin/dspace generate-sitemaps

...

DSpace uses the Apache Solr application underlaying the statistics. There is no need to download any separate software. All the necessary software is included. To understand all of the configuration property keys, the user should refer to DSpace Statistic Configuration for detailed information.

External database connection poolconnection pool

Note: The following uses Tomcat 7 as an example and links to documentation pertaining to that version of Tomcat. Consult the Tomcat migration guide on the specific requirements for your environment.

Before it builds a pool of database connections, DSpace always tries to look up an existing, pre-configured pool in a directory service (if such a service is provided). Many web application containers supply such a service and can be configured to provide the connection pool to DSpace. If DSpace does not find a pre-configured pool, each web application will fall back to creating its own pool using the settings in local.cfg.

There are some advantages to using an external database pool:

You can The ability to share one pool among several of DSpace's web applications—or even all of them. This can help economize database connections when one application uses many and another few. For example, if XMLUI needs 30 connections to run well at your site under peak load and OAI-PMH needs 5, you could connect them both to a pool of 35 connections, instead of letting each take 30 for a total of 60.
You can The ability to have different pool sizes for the web applications and the command line tools. For example, configure an external pool with generous settings for the web applications, and a much smaller pool for the command line applications in local.cfg. Note: the command line tools cannot use an externally configured pool, and always use the settings in local.cfg to build their own pool.
External database pooling often allows for more granular configuration of pool parameters and can even provide better performance than DSpace's fallback pooling (see the Tomcat JDBC Connection Pool documentation for more information).

DSpace applications will specifically look for an object named jdbc/dspace. The name is not configurable, but is specified in config/spring/api/core-hibernate.xml if you must know. You must configure the name of the directory object provided to your web application context(s) to match this. See below for an example in Tomcat 7.

An example in Tomcat 7 running on Ubuntu 16.04

First, you must make the JDBC driver for your database available to Tomcat. For example, the latest PostgreSQL JDBC driver can be downloaded from the PostgreSQL project website and placed in Tomcat's lib directory. The exact location of this directory varies depending on your operating system and Tomcat version, but on Ubuntu 16.04 with Tomcat 7 the location would be /usr/share/tomcat7/lib.

...

Code Block

Then add a <ResourceLink> to each web application's context configuration. The name parameter here is local to the application context, and must be jdbc/dspace:

Code Block

language	xml

    global='"jdbc/instance'"
    type='"javax.sql.DataSource'"
   />
...
</Context>

Notice that the global parameter in the ResourceLink matches the name of the global Resource. See the JNDI Datasource HOW-TO for more information about this configuration.

...

Essentially installing on Windows is the same as installing on Unix so please refer back to the main Installation Instructions section section.

Download the DSpace source from GitHub and unzip it (WinZip will do this)
If you install PostgreSQL, it's recommended to select to install the pgAdmin III tool. It provides a nice User Interface for interacting with PostgreSQL databases.
For all path separators use forward slashes (e.g. "/"). For example: "C:/dspace" is a valid Windows path. But, be warned that "C:\dspace" IS INVALID and will cause errors.

...

Database errors occur when you run ant fresh_install: There are two common errors that occur.

If your error looks like this:

it usually means you haven't yet added the relevant configuration parameter to your PostgreSQL configuration (see above), or perhaps you haven't restarted PostgreSQL after making the change. Also, make sure that the db.username and db.password properties are correctly set in [dspace]/config/dspace.cfg. An easy way to check that your DB is working OK over TCP/IP is to try this on the command line:

Code Block
psql -U dspace -W -h localhost

Enter the dspace database password, and you should be dropped into the psql tool with a dspace=> prompt.

Another common error looks like this:

it means that you likely either (a) don't have an internet connection to download the necessary GeoLite Database file (used for DSpace Statistics), or (b) the GeoLite Database file's URL is no longer valid.

Another common message looks like this:
Code Block
