elasticsearchHow do I enable Xpack security in Elasticsearch?

Enabling X-Pack Security in Elasticsearch requires a few steps:

1. Install the X-Pack plugin:

bin/elasticsearch-plugin install x-pack

2. Configure the X-Pack security settings in the elasticsearch.yml configuration file:

xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true

3. Create a password for the built-in elastic user:

bin/elasticsearch-setup-passwords auto

4. Restart the Elasticsearch service:

systemctl restart elasticsearch

5. Check the status of the X-Pack security feature:

curl -u elastic:<password> -XGET 'localhost:9200/_xpack?pretty'

The output should look like this:

{
  "build" : {
    "hash" : "...",
    "date" : "..."
  },
  "license" : {
    "status" : "active",
    "uid" : "...",
    "type" : "basic",
    "expiry_date_in_millis" : 0
  },
  "features" : {
    "security" : {
      "description" : "Security for the Elastic Stack",
      "available" : true,
      "enabled" : true
    }
  }
}

The available and enabled fields should both be true to indicate that X-Pack security is enabled.
