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
