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/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 (log4j2.xml) 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.
_default : Bare minimum configurations with field-guessing and managed schema turned
on by default, so as 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. You can turn off the field (for a collection, say mycollection) guessing by:
curl http://host:8983/solr/mycollection/config -d '{"set-user-property": {"update.autoCreateFields":"false"}}'
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).
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).
Various example SolrHome dirs contained in this directory may use “” 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), 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.
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 log4j2.xml file in “resources”.
It is also possible to setup log4j or other popular logging frameworks.
