Solr server
------------
This directory contains an instance of the Jetty Servlet container setup to
run Solr.
To run Solr:
cd $SOLR_INSTALL
bin/solr start
where $SOLR_INSTALL is the location where you extracted the Solr installation bundle.
Server directory layout
-----------------------
server/contexts
This directory contains the Jetty Web application deployment descriptor for the Solr Web app.
server/etc
Jetty configuration and example SSL keystore
server/lib
Jetty and other 3rd party libraries
server/logs
Solr log files
server/resources
Contains configuration files, such as the Log4j configuration (log4j.properties) for configuring Solr loggers.
server/scripts/cloud-scripts
Command-line utility for working with ZooKeeper when running in SolrCloud mode, see zkcli.sh / .cmd for
usage information.
server/solr
Default solr.solr.home directory where Solr will create core directories; must contain solr.xml
server/solr/configsets
Directories containing different configuration options for running Solr.
basic_configs : Bare minimum configuration settings needed to run Solr.
data_driven_schema_configs : Field-guessing and managed schema mode; use this configuration if you want
to start indexing data in Solr without having to design a schema upfront.
You can use the REST API to manage your schema as you refine your index
requirements.
sample_techproducts_configs : Comprehensive example configuration that demonstrates many of the powerful
features of Solr, based on the use case of building a search solution for
tech products.
server/solr-webapp
Contains files used by the Solr server; do not edit files in this directory (Solr is not a Java Web application).
Notes About Solr Examples
--------------------------
* SolrHome *
By default, start.jar starts Solr in Jetty using the default Solr Home
directory of "./solr/" (relative to the working directory of the servlet
container).
* References to Jar Files Outside This Directory *
Various example SolrHome dirs contained in this directory may use "<lib>"
statements in the solrconfig.xml file to reference plugin jars outside of
this directory for loading "contrib" plugins via relative paths.
If you make a copy of this example server and wish to use the
ExtractingRequestHandler (SolrCell), DataImportHandler (DIH), UIMA, the
clustering component, or any other modules in "contrib", you will need to
copy the required jars or update the paths to those jars in your
solrconfig.xml.
* Logging *
By default, Jetty & Solr will log to the console and logs/solr.log. This can
be convenient when first getting started, but eventually you will want to
log just to a file. To configure logging, edit the log4j.properties file in
"resources".
It is also possible to setup log4j or other popular logging frameworks.
