MySQL 如何向数据库授予复制权限

要授予复制权限，请使用GRANT REPLICATION SLAVE ON。

首先，从MySQL.user表中列出所有用户名和主机−

mysql> select user,host from mysql.user;

这将产生以下输出−

+------------------+-----------+
| user             | host      |
+------------------+-----------+
| Bob              | %         |
| Charlie          | %         |
| Robert           | %         |
| User2            | %         |
| mysql.infoschema | %         |
| mysql.session    | %         |
| mysql.sys        | %         |
| root             | %         |
| @UserName@       | localhost |
| Adam             | localhost |
| Adam Smith       | localhost |
| Chris            | localhost |
| David            | localhost |
| James            | localhost |
| John             | localhost |
| John Doe         | localhost |
| Mike             | localhost |
| User1            | localhost |
| am               | localhost |
| hbstudent        | localhost |
| mysql.infoschema | localhost |
| mysql.session    | localhost |
+------------------+-----------+
22 rows in set (0.00 sec)

让我们实现上述语法，在MySQL中向数据库授予复制权限 −

mysql> GRANT REPLICATION SLAVE ON *.* TO 'Mike'@'localhost';
Query OK, 0 rows affected (0.20 sec)

让我们检查授予是否成功 −

mysql> SHOW GRANTS FOR 'Mike'@'localhost';

这将产生以下输出−

+------------------------------------------------------+
| Grants for Mike@localhost                            |
+------------------------------------------------------+
| GRANT REPLICATION SLAVE ON *.* TO `Mike`@`localhost` |
+------------------------------------------------------+
1 row in set (0.04 sec)
