1、通過create user 或者alter user命令中帶account lock或者unlock設置用戶的lock狀態
create user語句默認用戶時unlock狀態，
~~~
mysql> create user test6@'localhost' identified by '123456' account lock;
Query OK, 0 rows affected (0.00 sec)
~~~
2、alter user 默認不會修改用戶的lock/unlock狀態
~~~
解鎖：
mysql> alter user 'test6'@localhost account unlock;
加鎖：
mysql> alter user 'test6'@localhost account lock;
~~~
報錯信息：
~~~
[root@mysql2 ~]# mysql -u test6 -p123456
mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 3118 (HY000): Access denied for user 'test6'@'localhost'. Account is locked.
~~~
