查看MYSQL數據庫中所有用戶
mysql> SELECT DISTINCT CONCAT('User: ''',user,'''@''',host,''';') AS query FROM mysql.user;
+---------------------------------------+
| query |
+---------------------------------------+
| User: 'cactiuser'@'%'; |
| User: 'common_user'@'%'; |
| User: 'dba'@'%'; |
| User: 'root'@'%'; |
| User: 'slave'@'%'; |
| User: 'wtgame'@'%'; |
| User: 'root'@'127.0.0.1'; |
| User: 'webman'@'127.0.0.1'; |
| User: 'root'@'192.168.166.200'; |
| User: 'cactiuser'@'192.168.166.202'; |
| User: 'root'@'192.168.166.202'; |
| User: ''@'localhost'; |
| User: 'cacti'@'localhost'; |
| User: 'cactiuser'@'localhost'; |
| User: 'dba'@'localhost'; |
| User: 'extmail'@'localhost'; |
| User: 'javauser'@'localhost'; |
| User: 'root'@'localhost'; |
| User: 'webman'@'localhost'; |
| User: ''@'localhost.localdomain'; |
| User: 'root'@'localhost.localdomain'; |

查看數據庫中具體某個用戶的權限
mysql> show grants for 'cactiuser'@'%';
+-------------------------------------------------------------------------------------------------------------------+
| Grants for cactiuser@% |
+-------------------------------------------------------------------------------------------------------------------+
| GRANT PROCESS, SUPER ON *.* TO 'cactiuser'@'%' IDENTIFIED BY PASSWORD '*DAFF917B80E3314B1ABECBA9DF8785AFD342CE89' |
| GRANT ALL PRIVILEGES ON `cacti`.* TO 'cactiuser'@'%' |
+-------------------------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)
mysql> select * from mysql.user where user='cactiuser' \G

查看user表結構 需要具體的項可結合表結構來查詢
mysql> desc mysql.user;
+-----------------------+-----------------------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-----------------------+-----------------------------------+------+-----+---------+-------+
| Host | char(60) | NO | PRI | | |
