Your password has expired. To log in you must change it using a client that supports expired passwords

msyql 5.7.11版本安装

mysql生成的root的临时密码是

2016-05-10T10:05:47.421912Z 1 [Note] A temporary password is generated for root@localhost: v:gNXSw5FTkw

使用

mysql -u root -p  v:gNXSw5FTkw 提示（中间重启的一次mysql，可能是重启的原因，正常情况下是可以登录的）

Your password has expired. To log in you must change it using a client that supports expired passwords

 

在stackoverflow找到了解决方法，连接地址：http://stackoverflow.com/questions/33387879/mysql-password-expired-cant-connect

解决办法：

[root@localhost bin]# ./mysqladmin -uroot -p password
Enter password:   //这里输入上面的v:gNXSw5FTkw
New password:    //重新输入新密码
Confirm new password: //重新输入新密码

问题解决！
