The MySQL server is running with the –skip-grant-tables option so it cannot execute this state

本文介绍: 3、退出数据库服务器，注释配置文件 #skip–grant–table，重启数据库服务器器。1、重启数据库服务器。2、链接数据库服务器。4、验证用户是否登录。

原因：链接数据库忘记用户密码，配置文件/etc/my.cnf中增加skip–grant–table 跳过密码登录，进入服务器修改密码时，出现如下报错信息：

mysql&gt; alter user root@'localhost' identified by '123';
ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement

解决方法：

1、重启数据库服务器

]# service mysql re start

2、链接数据库服务器

]# mysql

mysql> flush privileges; 刷新权限列表

mysql> alter user root@’local host‘ identified by ‘123’; 更改用户密码

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)

mysql> alter user root@'localhost' identified by '123';
Query OK, 0 rows affected (0.00 sec)

3、退出数据库服务器，注释配置文件 #skip–grant–table，重启数据库服务器器

4、验证用户是否登录

[root@master-2 mysql]# mysql -uroot -p123
