两种MySQL查询用户权限的方法-木庄网络博客

本文摘自PHP中文网，作者藏色散人，侵删。

介绍两种查看MySQL用户权限的两种方法

1、使用MySQL grants命令

mysql> show grants for username@localhost;
+---------------------------------------------------------------------+
| Grants for root@localhost                                           |
+---------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION |
+---------------------------------------------------------------------+

需要注意的是：

● username和ip的组合需要是在mysql.user表中存在的，具体可以通过 select * from mysql.user 命令查看

● ip地址如果是通配符格式需要加引号，例如：show grants for root@'172.%';

2、使用MySQL select命令

mysql> select * from mysql.user where user='root' and host='localhost' \G;
