ApsaraDB for Redis allows you to restart or rebuild a proxy node. This way, you can perform real-time disaster recovery drills. You can also perform O&M tasks when the service is unavailable or experiences a high latency.

Prerequisites

The ApsaraDB for Redis instance to which the proxy node belongs must meet the following requirements:

Impacts

Proxy restart and rebuild may result in transient connections, which affect existing connections. Make sure that your applications can automatically reconnect to the proxy node. We recommend that you restart or rebuild a proxy node during off-peak hours.

Procedure

  1. Log on to the ApsaraDB for Redis console and go to the Instances page. In the top navigation bar, select the region in which the instance is deployed. Then, find the instance and click its ID.
  2. In the left-side navigation pane, click Service Availability.
  3. In the Proxy Servers section, select the proxy node that you want to manage and click Restart.

  5. Click OK.
