mysql 5.7.14安装完后登陆报错，意思是密码过期

[root@mysql]# mysql -u root -p
Enter password: 
ERROR 1862 (HY000): Your password has expired. To log in you must change it using a client that supports expired passwords.

第一种方法：解决办法：

1.在my.cnf  mysqld 部分加入 skip-grant-tables 参数。

[mysqld]
skip-grant-tables

2.重启mysql数据库，然后登陆

[root@llmj-mysql-40-115 tools]# mysql -u root -p
Enter password:   #这里直接回车，不需要密码即可登陆

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)

第二种方法：

这种方法是自己太懒了，直接用Navicat连接数据修改mysql数据库中user表password_expired这个字段值为‘N’，就可以了。

首先修改 my.cnf 文件跳过密码登录

vi etc/my.cnf

1.配置好后 按Esc退出vi编辑 ：wq退出保存，

2. 重启mysql 

systemctl restart mysqld.service 

以上用的均是centos7命令，其他系统请注意....

3.Navicat直接连接 mysql数据库中user表password_expired这个字段值为‘N’，后返回来在吧my.cnf文件中配置  跳过登录的语句删除。重启MySQL就可以了。。。。哈哈哈哈！！！！！！！！！！机智
