1. Log in to the management console.
2. Click in the upper left corner and select a region and a project.
3. Click Service List. Under Databases, click GaussDB(for MySQL).
4. On the Instances page, click the target DB instance.
5. In the navigation pane, choose Accounts. On the displayed page, click Create Account. In the displayed dialog box, enter a username, authorize permissions for databases, enter a password, and confirm the password. Then, click OK.
