环境:

ubuntu14.04  mysql5.7

一、mysql5.7 密码过期问题

报错:

ERROR 1862 (HY000): Your password has expired. To log in you must change it using a client that supports expired passwords.

翻译:

错误1862(HY000):你的密码已经过期。登录必须改变它使用一个客户端,支持过期的密码。

解决方法:

1、 用忽略授权表的方法进入mysql

        vi /etc/my.cnf
   [mysqld]
   skip-grant-tables
   :wq! #保存退出
 

2、进入mysql,查看root用户的详细信息

        # mysql -u root -p
> use mysql
> select * from mysql.user where user='root' \G

3、把password_expired 改成不过期

        >  update user set password_expired='N' where user='root';
> flush privileges;
> quit
 

4、把 /etc/my.cnf 的 skip-grant-tables 这行注释掉

5、重启服务

     #service mysql restart
 

6、再次登陆 mysql 就正常了
