elasticsearchHow do I set up basic authentication for Elasticsearch?

Setting up basic authentication for Elasticsearch can be done using the X-Pack security feature. X-Pack security provides authentication, authorization, and encryption for the Elastic Stack.

To set up basic authentication, you first need to install X-Pack. This can be done by running the following command:

bin/elasticsearch-plugin install x-pack

Once X-Pack is installed, you can enable basic authentication by adding the following configuration to your elasticsearch.yml file:

xpack.security.authc.realms.native.native1.order: 0
xpack.security.authc.realms.native.native1.type: native

You can then create a user with the following command:

bin/elasticsearch-users useradd <username> -p <password> -r superuser

Once the user is created, you can log in to Elasticsearch using the username and password you provided.
