Elasticsearch ships with a script to run the SQL CLI in its bin directory:
$ ./bin/elasticsearch-sql-cli
The jar containing the SQL CLI is a stand alone Java application and the scripts just launch it. You can move it around to other machines without having to install Elasticsearch on them.
You can pass the URL of the Elasticsearch instance to connect to as the first parameter:
$ ./bin/elasticsearch-sql-cli https://some.server:9200
If security is enabled on your cluster, you can pass the username
and password in the form username:password@host_name:port
to the SQL CLI:
$ ./bin/elasticsearch-sql-cli https://sql_user:strongpassword@some.server:9200
Once the CLI is running you can use any query that Elasticsearch supports:
sql> SELECT * FROM library WHERE page_count > 500 ORDER BY page_count DESC;
author | name | page_count | release_date
