This topic describes how to restart an ApsaraDB for Redis instance to release all connections when the number of connections reaches the upper limit or performance issues occur.


During the restart, the instance may be disconnected within seconds. We recommend that you restart the instance during off-peak hours. Before you restart the instance, make sure that your application can reconnect to the instance.


  1. Log on to the ApsaraDB for Redis console.
  2. In the top navigation bar of the page, select the region where the instance is deployed.
  3. On the Instances page, find the instance that you want to restart and choose More > Restart in the Actions column.
