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

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> 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：

重启数据库服务器

     ]# service Mysql restart

链接数据库服务器

     ]# mysql

     mysql>  flush privileges;             刷新权限列表

     mysql> alter user root@'localhost' 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

验证用户是否登录

[root@master-2 mysql]# mysql -uroot -p123mysql: [Warning] Using a password on the command line interface can be insecure.Welcome to the MySQL monitor.
