Start AWS Instance

Ansible Setup

  1. Locally clone the fcrepo4-ansible project
  2. Follow the README and install the required software and set system environment variables 
  3. There are two configuration to choose from:
    1. Fedora 4 with a file-based database (default)
    2. Fedora 4 with a PostgreSQL database  
  4. Run
    cd /path/to/fcrepo4-ansible
    vagrant up --provider aws
  5. The Fedora 4 is accessible at this URL:  http://[SERVER IP]:8080/fcrepo/

Puppet Setup

  1. Locally clone the fcrepo-aws-puppet project
  2. Follow the README from the fcrepo-aws-puppet project
  3. There are two configurations to choose from:
    1. Single node, async-indexing (default)
      1. Includes YourKit agent for remote profiling
    2. Clustered


Fedora 4 can be run in a clustered configuration on AWS. We ran performance benchmarks using these additional java opts:

Code Block
# Clustering
JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.infinispan.cache_configuration=config/infinispan/clustered/infinispan.xml"
JAVA_OPTS="${JAVA_OPTS} -Djgroups.tcp.address=<aws-private-ip>"
JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.ispn.numOwners=2"
# The jgroups-ec2.xml file is included in ispn's jars
JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.ispn.jgroups.configuration=jgroups-ec2.xml"
# This property overwrites the S3 bucketname variable in jgroups-ec2.xml
JAVA_OPTS="${JAVA_OPTS} -Djgroups.s3.bucket=fcrepo4-cluster-0"


Most importantly, we used the jgroups-ec2 configuration, which enables auto-discovery of nodes by writing content into an S3 bucket.
