Restart a Redis cluster

You can restart all pods of the cluster. When an exception occurs in a database, you can try to restart it.

note

The pod role may change after the cluster restarts.

Steps​

  1. Restart a cluster.

    Configure the values of components and ttlSecondsAfterSucceed and run the command below to restart a specified cluster.

    kbcli cluster restart redis-cluster --components="redis" \
    --ttlSecondsAfterSucceed=30
    • components describes the component name that needs to be restarted.
    • ttlSecondsAfterSucceed describes the time to live of an OpsRequest job after the restarting succeeds.

  2. Validate the restart operation.

    Check the cluster status to identify the restart status.

    kbcli cluster list redis-cluster
    >
    NAME                 NAMESPACE        CLUSTER-DEFINITION        VERSION            TERMINATION-POLICY        STATUS         CREATED-TIME
    redis-cluster        default          redis                     redis-7.0.6        Delete                    Running        Apr 10,2023 19:20 UTC+0800
    • STATUS=Updating: it means the cluster restart is in progress.
    • STATUS=Running: it means the cluster has been restarted.
