#昊鼎王五：如何解决“mysql5.7密码过期ERROR 1862 (HY000): Your password has expired. To log in you must change”

环境：
Centos 7.2 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。

解决步骤：

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 ***************************
                  Host: localhost
                  User: root
           Select_priv: Y
           Insert_priv: Y
           Update_priv: Y
           Delete_priv: Y
           Create_priv: Y
             Drop_priv: Y
           Reload_priv: Y
         Shutdown_priv: Y
          Process_priv: Y
             File_priv: Y
            Grant_priv: Y
       References_priv: Y
            Index_priv: Y
            Alter_priv: Y

     password_lifetime: NULL
        account_locked: N
1 row in set (0.00 sec)

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

[root@hd205 mysql]# mysql -uroot -p
