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

正常使用的mysql，某天连接时突然出现：

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

不管是客户端，还是程序代码都报告此错。

解决方法:

打开命令行，执行 

#mysql -uroot -p --port=33999

Enter password:    输入密码。即可进入，然后重置密码 

#set password=password('password');

如此。就正常了。
