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 instance must meet the following requirements:
- The instance is a Community Edition instance or a Tair DRAM-based instance.
- The instance uses the cluster or read/write splitting architecture.
Procedure
Warning This operation may cause transient connections. We recommend that you perform this operation during off-peak hours and make sure that your application is configured to automatically reconnect to your instance.
- 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 that you want to manage resides. Then, find the instance and click its ID.
- In the left-side navigation pane, click Service Availability.
- In the Proxy Servers section, select the proxy node that you want to manage, and then click Restart.
- In the panel that appears, select Restart Mode.
- In-place Restart: restarts the proxy node.
- Rebuild Proxy: rebuilds the proxy node. If an issue cannot be fixed after the restart, select this mode.
- Click OK.
