用戶授權(quán)在mysql中使用grant命令就可以了，我相信各位都會有了解過了，下面小編為各位介紹一個Mysql下建立用戶授權(quán)權(quán)限例子，希望本文章對各位有幫助．

建立用戶，授權(quán)數(shù)據(jù)庫：

mysql> create user identified by 'admin123'; #建立主機為localhost，密碼為admin123的用戶byrd

Query OK, 0 rows affected (0.05 sec)

mysql> show grants for ; #查看byrd權(quán)限，USAGE表示連接權(quán)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; #用戶byrd、主機localhost對數(shù)據(jù)庫gbk擁有所有權(quán)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'; #建立用戶test，用戶gbk數(shù)據(jù)庫所有權(quán)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)

遠程連接同上：

mysql> grant all on gbk.* to 授權(quán)可連接主機' identified by 'admin123'; #這是Server端

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

補充：ALL PRIVILEGES權(quán)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 |
