The Solr stop Command

Beginner

Recently, many developers are evaluating alternatives to Google Custom Search or Amazon CloudSearch. The Apache Lucene library with front-end tools from Apache Solr and Elasticsearch provide alternatives for those looking to create a website search engine or expand their enterprise search capabilities.

During this evaluation period, typically in a local test environment, developers need to stop Solr. The solr stop command offers a fast way to stop the Solr service using a short list of settings.

Apache Solr Reference

1. About the solr stop command

The solr stop command will stop the Solr server as specified. It is a good idea to use the solr status command first to review the running instances of Solr.

The solr stop command is one of 12 commands within the main solr script.

The solr stop command itself has 4 options, also known as parameters.

2. Syntax for the solr stop command

The syntax for running solr stop is as follows.

$ bin/solr stop [-k key] [-p port] [-all] [-V]

The list of 4 options including default values are noted in the table below.

This syntax assumes your current working directory is the $SOLR_HOME directory for Solr, which for version 7 would be ~/solr-7.0.0/ in standalone mode for a local installation. When running in a production environment the directory locations may differ.

So the path to the location of the solr script is: ~/solr-7.0.0/bin/solr. Alternatively, the solr script can be run using the convention ./solr from within the bin directory.

When using Windows, the solr script is called using solr.cmd.
