Restart MySQL 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 mycluster --components="mysql" \
    --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. Check the cluster status to validate the restarting.

    kbcli cluster list mycluster
    >
    NAME        NAMESPACE   CLUSTER-DEFINITION   VERSION        TERMINATION-POLICY   STATUS     CREATED-TIME
    mycluster   default     mysql                mysql-8.0.33   Delete               Updating   Jul 05,2024 19:01 UTC+0800
    • STATUS=Updating: it means the cluster restart is in progress.
    • STATUS=Running: it means the cluster has been restarted.
