WARNING: Version 6.2 of the Elastic Stack has passed its EOL date.
This documentation is no longer being maintained and may be removed. If you are running this version, we strongly advise you to upgrade. For the latest information, see the current release documentation.
If a license is not already registered for the cluster, when you install X-Pack and start the cluster, it generates a basic license.
If you want to try all of the X-Pack features, you can start a 30-day trial. At the end of the trial period, you can purchase a subscription to keep using the full functionality of the X-Pack components.
When your license expires, X-Pack operates in a degraded mode. For more information, see License Expiration.
You can initiate a trial license only if your cluster has not already activated a trial license for the current major X-Pack version. For example, if you have already activated a trial for v6.0, you cannot start a new trial until v7.0. To check whether you can initiate a trial in your cluster, use the get trial status API.
To start a trial, use the start trial API.
For more information, see X-Pack License Settings.
You can update your license at runtime without shutting down your nodes. License updates take effect immediately. The license is provided as a JSON file that you install with the update license API.
You can use the get license API to retrieve the currently installed license.
