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...
