Resetting the MRS Component Database User Password

MRS cluster components use random default passwords for connecting to the DBService database. For operations security, you need to periodically reset the passwords of component database users.

This section applies only to MRS 3.1.2 or later. For versions earlier than MRS 3.1.2, see Changing the Passwords for Database Users of MRS Cluster Components.

Impact on the System

To reset passwords, you need to stop and then restart services, during which services are unavailable.

Resetting the Component Database User Password

  1. Log in to FusionInsight Manager and choose Cluster > Services.
  2. Click the name of the service whose database user password is to be reset, for example, Kafka, and click Stop Service on the Dashboard page.

    After confirming the impact of stopping the service, wait until the service is stopped.
