Buildout to Setup Solr Instance

There are different kinds of solr instances:

standalone

multi core

Solr Instance

Here is the buildout structure:

• BUILDOUT/etc/solr
  This will be the solr/home in the context.xml file.
  • context.xml
    The context.xml will be the symlink target on CATALINA_BASE/Catalina/localhost.
  • solr-app-version.war
  • solr.xml
  • mw - for MediaWiki core
    • conf
      • solrconfig.xml
      • schema.xml
      • db-data-config.xml
      • xslt
        • rss.xsl
        • google.xsl
    • data
    • lib

The data directory for indexing data will be set in file solrconfig.xml. We will set the datadir to something like BUILDOUT/var/solr. Here is a sample:

<config>
...
  <dataDir>/home/sean/buildout/var/solr</dataDir>
...
</config>

The lib could be included in war file. OR, use the lib in solrconfig.xml to set a specific lib.

perform the following actions:

A typical Solr application

A tpical solr application will have the following parts:

• context.xml on CATALINA_BASE/conf/Catalina/localhost
  • codebase to the solr.war
  • solr/home folder path as the Environment in context.xml. It could be the absolute path.
• solr/home folder has the following structure
  • solr.xml: defines the cores by give a name and the instance path.
    The instance directory could be absolute path. Each core has the following folder structure.
  • solr-core-name
    • conf: the solr configuration folder.
      • solrconfig.xml
      • schema.xml
      • db-data-config.xml
      • xslt transform templages
    • data: the index storage space.
    • lib: extra library files, such as JDBC driver for data importer.

Solr Multiple Cores and Multiple Indexes

Solr Multiple cores -> multiple indexes -> merge indexes.
