Manage user permissions on MongoDB databases

Create a user

1. Log on to the DMS console.
2. In the search box at the top of the left-side navigation pane, enter the name of the MySQL database whose permissions you want to manage. From the matched result, find the instance to which the database belongs.
3. Right-click the instance and select Account Management.
   
4. On the Account Management page, select a database from the drop-down list.
   
5. Click Create User in the upper-left corner.
6. In the Create User dialog box, set relevant parameters.
   
   1. Configure user information. Set the parameters as described in the following table.

      Parameter	Description
      Target Database	The database for which you want to create the user. Note If you select a database other than the admin database, the user to be created is a common user. If you select the admin database, the user to be created is a privileged user.
      User name	The name of the user. The name cannot contain Chinese characters. It can contain letters, digits, and special characters. The name can contain the following special characters: !#$%^&*()_+-=
      Password	The password that the user can use to log on to the database. To ensure data security, the password can be 8 to 32 characters in length and must contain at least three of the following character types: uppercase letters, lowercase letters, digits, and special characters. The password can contain the following special characters: !#$%^&*()_+-=
      Confirm Password	The password that the user can use to log on to the database. Enter the same password again to confirm the password.

   2. Grant permissions to the user.
      Note

      • Assume that you select the admin database:

        On the Current library permissions tab, you can grant permissions of different roles to the user. The roles are Common operation role, Administrator action role, Instance-level role, Cluster administrator role, Backup and Recovery roles, and Super role. For more information, see Permissions of different roles.

        On the Other library permissions tab, you can grant permissions on other databases in the current instance to the user.

      • Assume that you select a database other than the admin database:

        On the Current library permissions tab, you can grant permissions of Common operation role and Administrator action role to the user. For more information, see Permissions of different roles.

        You cannot grant permissions on other databases to the user on the Other library Permissions tab.

7. In the Create User dialog box, click OK.
   Note If the database instance is in Security Collaboration mode, SQL statements can be generated based on the parameters you set. However, the SQL statements may fail to be executed due to security rules. In this case, you can perform operations as prompted or contact the DBA or DMS administrator.
