修改密码出问题时，解决办法：

mysql -u root -p  v:AhlHqsKKd2+>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
New password:    //重新输入新密码
Confirm new password: //重新输入新密码

问题解决！
