Changing the Private IP Address for Read of a Read Replica

Scenarios

If the IP address of a read replica conflicts with other IP addresses, you can change it on the DB instance's Basic Information page to reduce application changes.

Constraints

If a DB instance has a read-only proxy instance, and the proxy instance contains only the read replica whose private IP address for read is to be changed and read weight is greater than 0, the private IP address for read of the read replica cannot be changed.

Changing a Private IP Address for Read

1. Log in to the management console.
2. Click in the upper left corner and select a region and project.
3. Click in the upper left corner of the page and choose Databases > TaurusDB.
4. On the Instances page, click the instance name to go to the Basic Information page.
5. In the Node List area, locate a read replica and click Change in the Private IP Address for Read column.
6. In the displayed dialog box, enter a new private IP address for read and click OK.

   An in-use IP address cannot be used as the new private IP address for read.
