Creating an RDS for MySQL Instance

Create an RDS for MySQL instance as a DR instance and select the VPC you configured for the instance.

Preparations

For fine-grained permissions management on Huawei Cloud resources, use Identity and Access Management (IAM) to create an IAM user and a user group and grant the user specific permissions. For details, see Creating a User and User Group and Granting Permissions.

Procedure

  1. Go to the Buy DB Instance page.
  2. Select AP-Singapore for Region. Configure instance information and click Buy.

    Configure the instance by referring to Resource Planning. For details, see Buying an RDS for MySQL Instance.
