Use this procedure to renew or update an existing license key or file, switch from a license key to a license file, or switch from a license file to a license key.
|
|
|
|
> **Note:** To request a new license to renew or expand your InfluxDB Enterprise cluster, contact [sales@influxdb.com](mailto:sales@influxdb.com).
|
|
|
|
To update a license key or file, do the following:
|
|
|
|
1. If you are switching from a license key to a license file (or vice versa), delete your existing license key or file.
|
|
2. **Add the license key or file** to your [meta nodes](/enterprise_influxdb/v1/administration/config-meta-nodes/#enterprise-license-settings) and [data nodes](/enterprise_influxdb/v1/administration/config-data-nodes/#enterprise-license-settings) configuration settings. For more information, see [how to configure InfluxDB Enterprise clusters](/enterprise_influxdb/v1/administration/configuration/).
|
|
3. **On each meta node**, run `service influxdb-meta restart`, and wait for the meta node service to come back up successfully before restarting the next meta node.
|
|
The cluster should remain unaffected as long as only one node is restarting at a time.
|
|
4. **On each data node**, run `killall -s HUP influxd` to signal the `influxd` process to reload its configuration file.
