当忘记MySQL数据库的用户密码时，可以通过在配置文件中添加skip-grant-tables选项跳过权限检查登录，然后重启服务，修改root用户的密码，并刷新权限。之后需要取消该选项并再次重启服务以确保安全。最后验证新密码是否生效。

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：

1、重启数据库服务器

]# service mysql restart

2、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

4、验证用户是否登录

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