Configuring and Changing a Private IP Address

Scenarios

You can change private IP addresses after migrating data from on-premises databases or other cloud databases to GaussDB(for MySQL).

Constraints

After read/write splitting is enabled, the private IP address cannot be changed.
If there is an HTAP instance, the private IP address of the GaussDB(for MySQL) instance cannot be changed.
After a private IP address is changed, the domain name needs to be resolved again. This operation takes several minutes and may interrupt database connections. You are advised to change a private IP address during off-peak hours.

Configuring the Private IP Address of a DB Instance

When you buy an instance, select a VPC and subnet on the Buy DB Instance page. Then, a private IP address will be automatically assigned to your instance. You can also enter a private IP address.

You can change the private IP address of an existing GaussDB(for MySQL) instance.

Log in to the management console.
Click in the upper left corner and select a region and project.

On the Instances page, click the instance name to go to the Basic Information page.
In the Network Information area, click Modify under Private IP Address.
In the displayed dialog box, enter a new private IP address and click OK.

An in-use IP address cannot be used as the new private IP address of the DB instance.
