Configuring and Changing a Private IP Address
Scenarios
You can plan and change private IP addresses after migrating 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.
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. Therefore, 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.
