mysql 分配权限

有时候你没有其他账号，或者你把账号很邪恶的设置成用户名密码都是 ‘’的时候，

你输入mySql是采用默认用户登录的 即使-u也没用

那么如何赋予 ‘’其他权限呢。

在linux 终端执行：

1.killall -TERM mysqld  

2. 

[root@TSMIS bin]# /etc/init.d/mysqld start  --skip-grant-tables   

  3.

3.1 用登录mysql 

然后就可以grant all on *.* to ''@'localhost' identified by '';

搞定 

Insert mode

[root@localhost mysql]# killall -TERM mysqld

[root@localhost mysql]# /etc/init.d/mysql start --skip-grant-tables;

Starting MySQL.                                            [  OK  ]

[root@localhost mysql]# mysql

TSMIS软件会把mysql的数据迁移到  $TSMISi目录下，所以我们要修改etc init.d mysql 下的datafile的路径，然后重启就可以了
