Creating a User

Scenarios

Multiple users with different permissions can be created to access a DB instance or database, but the permissions of these users cannot exceed the operation permissions of the account.

Procedure

1. On the top menu bar, choose Account Management > User Management.
2. On the displayed page, click Create User. Then, configure required information, such as basic information, advanced settings, global permissions, object permissions, and roles, and click Save. In the displayed dialog box, click OK. For details, see Table 2.
   

   The role function is available only to MySQL 8.0.

   You can click Add DAS IP Address to add the IP address of the DAS server to the user's host. In the user list, you can view all created users, or locate a user and click Edit and Delete in the Operation column to manage it.

   Table 1 describes the user permissions briefly. For details about permission usages and explanations, visit the official website.
