your password has expired ,to log in you must change it using a client that  supports expired passwords

您的密码已经过期，要登录您必须使用一个客户端来更改它。

支持密码到期
解决错误方法
1.在my.cnf  mysqld 部分加入 skip-grant-tables 参数。[mysqld]
skip-grant-tables2.重启mysql数据库，然后登陆

3.查看mysql的用户状态>select host,user,password_expired,account_locked from mysql.user;
+-----------+-----------+------------------+----------------+
| host      | user      | password_expired | account_locked |
+-----------+-----------+------------------+----------------+
| localhost | root      | Y                | N              |
| localhost | mysql.sys | N                | Y              |
+-----------+-----------+------------------+----------------+
3 rows in set (0.00 sec)password_expired ：y说明密码已经过期，可以改成N,就是未过期>update mysql.user set password_expired='N';
Query OK, 1 row affected (0.03 sec)
Rows matched: 2  Changed: 1  Warnings: 0
4.然后注释掉skip-grant-tables参数重启mysql，用过期的密码就可以登陆了，登陆之后可以用下面的命令修改密码
>alter user user() identified by '123456';
Query OK, 0 rows affected (0.03 sec)>flush privileges;
Query OK, 0 rows affected (0.03 sec)
