Binding and Unbinding an EIP¶
Scenarios¶
You can bind an EIP to a GaussDB(openGauss) DB instance for public access and can unbind the EIP from a GaussDB(openGauss) DB instance as required.
Important
To ensure that the database can be accessed, the security group used by the database must have the permission to access the database port. For example, if the database port is 1611, ensure that the security group has the permission to access port 1611.
Precautions¶
You can bind an EIP to a CN only.
If a DB instance has already been bound with an EIP, you must unbind the EIP from the DB instance first before binding a new EIP to it.

Log in to the management console.
Click
in the upper left corner and select a region and a project.Click Service List. Under Database, click GaussDB.
