UCLALib Ansible Role: Solr

Deploys Apache Solr on RHEL servers

Dependencies

• uclalib_role_java
• uclalib_role_apache
• uclalib_role_tomcat
• uclalib_role_iptables

This role is capable of deploying Solr in the following configurations:

• Standalone: a single Solr instance
• Master: a Solr Master instance
• Slave: a Solr Slave instance sending replication requests to a Solr Master

Variables

solr_version - defines the version of Solr to use (e.g. 4.2.0, etc.)

solr_url - defines the URL to download Solr

solr_base - defines the location of Solr Tomcat installation directory

solr_home - defines the location of Solr Index home directory

solr_cores - the dictionary list of all Solr cores to be used in this instance

• ident - defines the names of the cores to configure within this Solr instance
• type - defines the external application using the solr core (e.g. default, drupal, etc).
  • the type variable is used in conjunction with application specific solr configuration files and the solrconfig.xml file. You will need to manually put the appropriate files in the files and templates directory for this role.
    • the naming convention for solr configuration files is: appname_solr-conf
    • the naming convention for the solrconfig.xml file is: solrconfig_appname.j2

solr_instance_type - define the type of solr instane to deploy (0 = standalone ; 1 = master ; 2 = slave)

solr_master_host - defines the hostname of the Solr Master (only necessary for a master/slave config)
