In Data Management (DMS), you can manage users for MongoDB databases and grant the users the permissions of different roles. The roles are Common operation role, Administrator action role, Instance-level role, Cluster administrator role, Backup and Recovery roles, and Super role.

Prerequisites

  • A MongoDB database is used.
  • You are assigned a required role for the MySQL database instance that is registered in DMS. The role varies based on the control mode of the instance. The following table describes the details.
    Control mode Role requirement
    Security Collaboration You must be a DMS administrator, a database administrator (DBA), or the owner of the relevant database instance.
    Stable Change No specific role is required.
    Flexible Management No specific role is required.

Create a user

  1. Log on to the DMS console.
  2. On the Account Management tab, select a database from the drop-down list.
    Select a database from the drop-down list
  3. Click Create User in the upper-left corner.
  4. In the Create User dialog box, perform the following steps:
    Create User dialog box
    1. Configure user information. Set the parameters that are 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 regular 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.
      • The name 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 must 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 password again to confirm the password.
    2. Grant permissions to the user.
      Note
      • If 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.

      • If 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.

  5. Click Confirm.
    Note If the database instance is managed 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 a database administrator (DBA) or DMS administrator.

Edit or delete a user

  1. Log on to the DMS console.
  2. On the Account Management tab, select a database from the drop-down list.
  3. On the Account Management page, find the user whose information you want to edit and click Edit in the Operation column.
    Edit
