Elasticsearch Get Version is a command that allows you to check the current version of Elasticsearch installed on your system.

To check your Elasticsearch version, you can use the Elasticsearch Get Version command, which is typically invoked by running the command `elasticsearch -v` or `elasticsearch --version`.

The Elasticsearch Get Version command will output the version number of Elasticsearch, such as 7.10.2 or 8.4.3.

Prerequisites

To get started with checking your Elasticsearch version, you'll need to ensure a few prerequisites are in place.

Elasticsearch needs to be installed and running, and Kibana also needs to be installed and running.

To check if Elasticsearch is running, execute the following command in the terminal: `curl http://localhost:9200/_cluster/health?pretty`. You should receive output containing information about your instance of Elasticsearch.

You can confirm that Kibana is running by pointing a browser to the following url: `http://localhost:5601/app/kibana`. If the Kibana UI comes up in your browser set to the default Discover page, you're good to go.

If either Elasticsearch or Kibana is not running, be sure to start them up before moving forward.

Here are the system requirements in a nutshell:

  • Elasticsearch needs to be installed and running.
  • Kibana needs to be installed and running.

Checking Elasticsearch Version

You can check the Elasticsearch version using the curl command from the command line. Execute the curl command `curl -XGET 'http://localhost:9200'` to get information about your version of Elasticsearch.

This method is simple and straightforward, and it will show you the version number in the output. For example, if you're running Elasticsearch 6.6.1, the output will contain the version number in the JSON object.

Alternatively, you can use the elasticsearch executable to check the version. Navigate to the Elasticsearch installation directory and run the command `bin/elasticsearch --version`. This will output the version number and other information about the Elasticsearch installation.

If you're not sure which version of Elasticsearch you're running, you can check the output of the curl command or the elasticsearch executable to see the version number.

Here are some common ways to check the Elasticsearch version:

  • Using curl: `curl -XGET 'http://localhost:9200'`
  • Using elasticsearch executable: `bin/elasticsearch --version`
  • Checking the output of the curl command or elasticsearch executable for the version number.

Note: If the version number shown in your output is different from the version you've installed, you may have more than one installation of Elasticsearch on your machine.
