Start AWS Instance

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

Clustered Configuration

To run a clustered configuration, locally update fcrepo-aws-puppet/modules/tomcat7/manifests/init.pp  uncommenting the clustered $repo_config and $etc_default_tomcat elements, and commenting out the previous values of those elements.

• From

      $repo_config = 'classpath:/config/async-indexing/repository.json',
  #    $repo_config = 'classpath:/config/clustered/repository.json',
      $etc_default_tomcat = 'tomcat7/default-tomcat7.erb',
  #    $etc_default_tomcat = 'tomcat7/default-tomcat7-clustered.erb',

• To

  #    $repo_config = 'classpath:/config/async-indexing/repository.json',
      $repo_config = 'classpath:/config/clustered/repository.json',
  #    $etc_default_tomcat = 'tomcat7/default-tomcat7.erb',
      $etc_default_tomcat = 'tomcat7/default-tomcat7-clustered.erb',

  Note, for the clustered configuration, start as many instances as desired.

  • All clustered instances will automatically join the same cluster
