If a host in an ApsaraDB for MyBase dedicated cluster has performance problems or other problems, you can restart the host on the Hosts page.

Prerequisites

A host is created in a MyBase for MySQL dedicated cluster. For more information, see Add hosts to a MyBase for MySQL dedicated cluster.

Procedure

  1. Log on to the ApsaraDB for MyBase console.
  2. In the top navigation bar, select the region where you want to create a dedicated cluster.
    Select a region
  3. In the left-side navigation pane, click Clusters. Find the dedicated cluster that you want to manage and click Details in the Actions column.
  4. In the left-side navigation pane, click Hosts.
  5. Find the host that you want to restart, and click More > Restart Host in the Actions column.
  6. On the Restart Host page, click Restart.
    Note
    • When the host is restarted, the primary instance that runs on the host becomes the secondary instance on anther host after a primary/secondary switchover. During the switchover, one or two transient connections may occur.
    • The time required to restart the host varies based on the duration of the primary/secondary switchover.
    • If the host is restarted when an instance is being created or migrated, a longer time is required to create or migrate the instance.
