The simple act of installing DSpace is actually quite simple, as changing between DSpace versions (eg between 1.6 and 1.7) can be done in a few minutes, however is it the installation and configuration of the prerequisites that is usually time consuming and difficult. Within Ubuntu, this is standard stuff, so we can have Ubuntu do all of that dirty work for us. The following is steps that are performed from Terminal, the command line interface in Ubuntu.
This how-to was originally written for Ubuntu 10.10 (Maverick Meerkat) and has been tested with Ubuntu 11.04 (Natty Narwhal).

Install Prerequisites
Make sure your sources are up to date before beginning
Code Block |
---|
sudo apt-get update
|
Install the server stack of Tomcat (web server) and PostgreSQL (database)
Code Block |
---|
sudo apt-get install tasksel
sudo tasksel
|
Select the following packages
Code Block [*] LAMP server [*] PostgreSQL database [*] Tomcat Java server
Install the Compile / Build tools
Code Block |
---|
sudo apt-get install ant maven2
|
...
Create the database user (dspace)
Code Block |
---|
sudo su postgres
createuser -U postgres -d -A -P dspace
exit
|
Allow the database user (dspace) to connect to the database
Code Block |
---|
sudo vi /etc/postgresql/8.4/main/pg_hba.conf
# Add this line to the configuration: local all dspace md5
sudo service postgresql restart
|
Create the dspace database
Code Block |
---|
createdb -U dspace -E UNICODE dspace
|
Configure Tomcat to know about the DSpace webapps.
Code Block |
---|
sudo vi /etc/tomcat6/server.xml
# Insert the following chunk of text just above the closing </Host>
<!-- Define a new context path for all DSpace web apps -->
<Context path="/xmlui" docBase="/dspace/webapps/xmlui" allowLinking="true"/>
<Context path="/sword" docBase="/dspace/webapps/sword" allowLinking="true"/>
<Context path="/oai" docBase="/dspace/webapps/oai" allowLinking="true"/>

Download and Install DSpace

the

directory.

Code Block |

sudo mkdir /dspace

Download the Source Release
The source release allows you to customize every aspect of DSpace. This step downloads the compressed archive from SourceForge, and unpacks it in your current directory. The dspace-1.x.x-src-release directory is typically referred to as \to as [dspace-src\]. Wiki Markup
Code Block |
---|
wget http://sourceforge.net/projects/dspace/files/DSpace%20Stable/1.7.2/dspace-1.7.2-src-release.tar.bz2
tar -xvjf dspace-1.7.2-src-release.tar.bz2
|
...
The source release that has been obtained is human readable source code, and must be compiled to machine code for the server to run it. "mvn package" compiles the source code, and "ant" will do all the work necessary to initialize the database with the DSpace schema, and copy all of the compiled machine code to a location where the web server can serve it.

Fix Tomcat permissions, and restart the Tomcat server
...
This guide follows the convention where the tomcat user will own all of the files in \files in [dspace\], so we have to change the owner of the files to tomcat6. Restarting tomcat will deploy the dspace webapps that are now ready to be viewed.
Code Block |
---|
sudo chown tomcat6:tomcat6 /dspace -R sudo service tomcattomcat6 restart |
Test it out in your browser

An optional step that can be done after installation would be to switch to the Sun/Oracle Java JDK. The tasksel task to install Tomcat installs the default OpenJDK which is a viable form of Java, however the official recommendation of DSpace is to use the Sun/Oracle Java JDK which offers better performance and other proprietary enhancements.

Oracle has changed their partner distribution license, which means that Canonical/Ubuntu has had to purge Sun-Java-6 from their repository. Thus, updating Ubuntu will remove Sun-Java from your system, and installing Sun-Java from the partner repository will no longer work. See more: https://lists.ubuntu.com/archives/ubuntu-security-announce/2011-December/001528.html |
Enable the Canonical Partners repository.
The Sun Java is available in the partners repository which makes for an easy installation. From the GUI this can be changed by going to Software Sources. Change "natty" to the name of the Ubuntu version you're using (if you aren't using Ubuntu 11.04)
Code Block |
---|
sudo vi /etc/apt/sources.list
# Uncomment the line: deb http://archive.canonical.com/ubuntu natty partner
sudo apt-get update
|
Install Sun Java
Code Block |
---|
sudo apt-get install sun-java6-jdk sun-java6-plugin
|
...
First we list the available jdk's installed on the system, then we set the sun java to be the new default.
Code Block |
---|
sudo update-java-alternatives -l
# java-6-openjdk 1061 /usr/lib/jvm/java-6-openjdk
# java-6-sun 63 /usr/lib/jvm/java-6-sun
sudo update-java-alternatives -s java-6-sun
|
Tomcat ignores the system default and continues to use OpenJDK. To make Tomcat use Sun Java instead, add the following line to /etc/default/tomcat6:
Code Block |
---|
JAVA_HOME=/usr/lib/jvm/java-6-sun
|
You will need to restart Tomcat to make it pick up the change (sudo service tomcat6 restart).
