用户授权在mysql中使用grant命令就可以了，我相信各位都会有了解过了，下面小编为各位介绍一个Mysql下建立用户授权权限例子，希望本文章对各位有帮助．

建立用户，授权数据库：

mysql> create user identified by 'admin123'; #建立主机为localhost，密码为admin123的用户byrd

Query OK, 0 rows affected (0.05 sec)

mysql> show grants for ; #查看byrd权限，USAGE表示连接权限

+-------------------------------------------------------------------------------------------------------------+

| Grants for |

+-------------------------------------------------------------------------------------------------------------+

| GRANT USAGE ON *.* TO IDENTIFIED BY PASSWORD '*01A6717B58FF5C7EAFFF6CB7C96F7428EA65FE4C' |

+-------------------------------------------------------------------------------------------------------------+

1 row in set (0.00 sec)

mysql> select user,host from mysql.user;

+------+-----------+

| user | host |

+------+-----------+

| root | 127.0.0.1 |

| root | ::1 |

| root | lamp |

| byrd | localhost |

| root | localhost |

+------+-----------+

5 rows in set (0.00 sec)

mysql> grant all on gbk.* to; #用户byrd、主机localhost对数据库gbk拥有所有权限

Query OK, 0 rows affected (0.01 sec)

mysql> show mysqls for ;

+-------------------------------------------------------------------------------------------------------------+

| Grants for |

+-------------------------------------------------------------------------------------------------------------+

| GRANT USAGE ON *.* TO IDENTIFIED BY PASSWORD '*01A6717B58FF5C7EAFFF6CB7C96F7428EA65FE4C' |

| GRANT ALL PRIVILEGES ON `gbk`.* TO |

+-------------------------------------------------------------------------------------------------------------+

2 rows in set (0.00 sec)

mysql> flush privileges;

mysql> grant all on gbk.* to identified by 'admin123'; #建立用户test，用户gbk数据库所有权限，同上

mysql> show grants for ;

+-------------------------------------------------------------------------------------------------------------+

| Grants for |

+-------------------------------------------------------------------------------------------------------------+

| GRANT USAGE ON *.* TO IDENTIFIED BY PASSWORD '*01A6717B58FF5C7EAFFF6CB7C96F7428EA65FE4C' |

| GRANT ALL PRIVILEGES ON `gbk`.* TO|

+-------------------------------------------------------------------------------------------------------------+

2 rows in set (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

远程连接同上：

mysql> grant all on gbk.* to 授权可连接主机' identified by 'admin123'; #这是Server端

[root@lamp ~]# /usr/local/mysql/bin/mysql -uroot -p'admin123' -h hk.t4x.org #这是client端

补充：ALL PRIVILEGES权限包括：

mysql> show grants for ;

+-------------------------------------------------------------------------------------------------------------+

| Grants for |

| GRANT USAGE ON *.* TO IDENTIFIED BY PASSWORD '*01A6717B58FF5C7EAFFF6CB7C96F7428EA65FE4C' |

| GRANT ALL PRIVILEGES ON `gbk`.* TO |

+-------------------------------------------------------------------------------------------------------------+

mysql> revoke insert on `gbk`.* from ;

Query OK, 0 rows affected (0.00 sec)

mysql> show grants for ;

+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

| Grants for |

+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

| GRANT USAGE ON *.* TO IDENTIFIED BY PASSWORD '*01A6717B58FF5C7EAFFF6CB7C96F7428EA65FE4C' |

| GRANT SELECT, UPDATE, DELETE, CREATE, DROP, REFERENCES, INDEX, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, EVENT, TRIGGER ON `gbk`.* TO |
