PolarDB for MySQL provides multiple system accounts for operations such as background O&M. In most cases, you do not need to manage the permissions and authorized operations of these system accounts.
| Account | Description |
|---|---|
|
root (MySQL 5.6 and 8.0) aliyun_root (MySQL 5.7) |
The account that is used to locally manage instances. For example, you can use this account to reconfigure the parameters that are related to the database engine and query the status of instances. |
| aurora | The account that is used to remotely manage instances. If an instance is faulty, you can use this account to log on to and manage the instance. For example, you can perform a primary/secondary switchover and monitor instances. |
| replicator | The account that is used to replicate or synchronize data between the primary and secondary instances. |
Note Do not use one of the names of the preceding system accounts when you create a database
account.
