Solr

Running a local SolrCloud Cluster

At times, it is important to do manual testing on a running server, and in many cases it is a good idea to test in a clustered environment to ensure that features play nice both locally and across nodes. To lower the barrier for realistic local testing, there is a script at dev-tools/scripts/cloud.sh.

Note
 This script only supports POSIX environments. There is no similar .bat script at this time.

Typical usage of the script is:

  1. Copy the script to a location outside the ./solr/ working copy such as <GIT_CHECKOUT>/../solr-testing. Trying to use it from within the working copy will leave you fighting version control to avoid checking in files.

  2. Edit the script to provide a proper back reference to your working copy for DEFAULT_VCS_WORKSPACE (the default is ../code/solr)

  3. Start a local zookeeper instance. This zookeeper must be running on localhost, but the port can be adjusted with a -z option passed to the script. docker run -p 2181:2181 zookeeper is one option to start up a local Zookeeper.

  4. run ./cloud.sh new -r

The command in the final step will:

  1. Recompile and package (-r) the solr checkout found at DEFAULT_VCS_WORKSPACE (but not run the tests).

  2. The tarball produced by step 1 is then extracted in a directory that is a peer to cloud.sh and named for the current date (such as ./2021-02-21).

  3. A node at the top level of zookeeper is created and named for the canonical path of this directory to serve as a zkchroot for this deployment.

  4. Start solr on ports 8981, 8982, 8983 and 8984 with listening debugger ports on 5001, 5002, 5003, and 5004.

  5. Each solr instance will place its data and solr.log in a corresponding directory such as ./2021-02-21/n1, ./2021-02-21/n2 etc.

The script supports start, stop and restart commands, and a variety of options detailed in the extensive introductory comment in cloud.sh.
