REPLICATION CLIENT Privilege

GRANT

The following examples demonstrate grant of a single privilege. A single GRANT statement can grant multiple privileges at the same scope by providing a comma-separated list of the privileges.

To grant the REPLICATION CLIENT privilege at global scope, replace the user specification ('USERNAME'@'HOSTNAME') in the following query to align to your requirements:

GRANT REPLICATION CLIENT
  ON *.*
  TO 'USERNAME'@'HOSTNAME';

REVOKE

The following examples demonstrate revoke of a single previously-granted privilege. A single REVOKE statement can revoke multiple privileges at the same scope by providing a comma-separated list of the privileges.

To revoke the REPLICATION CLIENT privilege at global scope, replace the user specification ('USERNAME'@'HOSTNAME') in the following query to align to your requirements:

REVOKE REPLICATION CLIENT
  ON *.*
  FROM 'USERNAME'@'HOSTNAME';

SHOW Output

A user's privileges can be displayed using the SHOW GRANTS statement.

If the REPLICATION CLIENT privilege is present, it will be shown as REPLICATION CLIENT in the output. For example:

SHOW GRANTS FOR 'app_user'@'192.0.2.%';

+-----------------------------------------------------------+
| Grants for app_user@192.0.2.%                             |
+-----------------------------------------------------------+
| GRANT REPLICATION CLIENT ON *.* TO 'app_user'@'192.0.2.%' |
+-----------------------------------------------------------+

Privilege Failure

An error message is raised if an operation fails due to insufficient privileges. For example:

SHOW MASTER STATUS\G

ERROR 1045 (HY000): [11281] Permission denied: User 'USERNAME'@'HOSTNAME' is missing REPLICATION CLIENT on *.*; transaction aborted
