This topic describes how to create an account that is used to manage the databases of an ApsaraDB RDS for MariaDB instance.

Account types

ApsaraDB RDS for MariaDB supports two types of accounts: privileged accounts and standard accounts. You can manage all accounts and databases of your RDS instance in the ApsaraDB RDS console.
Account type Description
Privileged account
  • You can create and manage privileged accounts by using the ApsaraDB RDS console or API operations.
  • Only one privileged account is allowed per RDS instance. A privileged account has the permissions to manage all databases and standard accounts of the RDS instance where the privileged account is created.
  • A privileged account allows you to manage permissions at fine-grained levels. For example, you can grant each standard account the permissions to query specific tables of the RDS instance where the privileged account is created.
  • A privileged account has all the permissions on the databases of the RDS instance where the privileged account is created.
  • A privileged account has permissions to disconnect all the standard accounts of the RDS instance where the privileged account is created.
Standard account
  • You can create and manage standard accounts by using the ApsaraDB RDS console, API operations, or SQL statements.
  • More than one standard account is allowed per RDS instance. The maximum number of standard accounts that are allowed varies based on the used database engine.
  • You must manually grant the permissions on specific databases to each standard account.
  • A standard account does not have the permissions to create, manage, or disconnect other accounts of the RDS instance where the standard account is created.
