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
** 1. row ***

3、把password_expired 改成不过期
update user set password_expired='N' where user='root';
> flush privileges;
> quit
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
