- Default Solr Home Directory
- =============================
- This directory is the default Solr home directory which holds
- configuration files and Solr indexes (called cores).
- Basic Directory Structure
- -------------------------
- The Solr Home directory typically contains the following...
- * solr.xml *
- This is the primary configuration file Solr looks for when starting;
- it specifies high-level configuration options that apply to all
- of your Solr cores, such as cluster-wide SolrCloud settings like
- the ZooKeeper client timeout.
- In addition, you can also declare Solr cores in this file, however
- it is recommended to just use automatic core discovery instead of
- listing cores in solr.xml.
- If no solr.xml file is found, then Solr assumes that there should be
- a single SolrCore named "collection1" and that the "Instance Directory"
- for collection1 should be the same as the Solr Home Directory.
- For more information about solr.xml, please see:
- https://cwiki.apache.org/confluence/display/solr/Solr+Cores+and+solr.xml
- * Individual SolrCore Instance Directories *
- Although solr.xml can be configured to look for SolrCore Instance Directories
- in any path, simple sub-directories of the Solr Home Dir using relative paths
- are common for many installations.
- * Core Discovery *
- During startup, Solr will scan sub-directories of Solr home looking for
- a specific file named core.properties. If core.properties is found in a
- sub-directory (at any depth), Solr will initialize a core using the properties
- defined in core.properties. For an example of core.properties, please see:
- example/solr/collection1/core.properties
- For more information about core discovery, please see:
- https://cwiki.apache.org/confluence/display/solr/Moving+to+the+New+solr.xml+Format
- * A Shared 'lib' Directory *
- Although solr.xml can be configured with an optional "sharedLib" attribute
- that can point to any path, it is common to use a "./lib" sub-directory of the
- Solr Home Directory.
- * ZooKeeper Files *
- When using SolrCloud using the embedded ZooKeeper option for Solr, it is
- common to have a "zoo.cfg" file and "zoo_data" directories in the Solr Home
- Directory. Please see the SolrCloud wiki page for more details...
