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 'byrd'@'localhost' 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 'byrd'@'localhost'; #查看byrd权限，，USAGE表示连接权限
+-------------------------------------------------------------------------------------------------------------+
| Grants for byrd@localhost |
+-------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'byrd'@'localhost' 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 'byrd'@'localhost'; #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 'byrd'@'localhost';
+-------------------------------------------------------------------------------------------------------------+
| Grants for byrd@localhost |
+-------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'byrd'@'localhost' IDENTIFIED BY PASSWORD '*01A6717B58FF5C7EAFFF6CB7C96F7428EA65FE4C' |
| GRANT ALL PRIVILEGES ON `gbk`.* TO 'byrd'@'localhost' |
+-------------------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)

mysql> flush privileges;
mysql> grant all on gbk.* to test@'localhost' identified by 'admin123'; #建立用户test，用户gbk数据库所有权限，同上
mysql> show grants for 'test'@'localhost';
+-------------------------------------------------------------------------------------------------------------+
| Grants for test@localhost |
+-------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'test'@'localhost' IDENTIFIED BY PASSWORD '*01A6717B58FF5C7EAFFF6CB7C96F7428EA65FE4C' |
| GRANT ALL PRIVILEGES ON `gbk`.* TO 'test'@'localhost' |
+-------------------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)
Query OK, 0 rows affected (0.00 sec)
远程连接同上：
