解决“OperationalError: (1862, 'Your password has expired. To log in you must change it using ...”

1.问题描述

在64位的ubuntu14.10下进行Django框架开发，在测试mysql是否可以连通时出现以下信息：

OperationalError:(1862,'Yourpasswordhasexpired.Tologinyoumustchangeitusingaclientthatsupportsexpiredpasswords.')
>>>

由上面的"OperationalError:(1862,'Yourpasswordhasexpired.Tologinyoumustchangeitusingaclientthatsupportsexpiredpasswords.')"可知，mysql用户的密码过期了

但我记得在安装完mysql后设置了root用户的密码为123456，且执行以下命令能正常进入mysql的shell：

mysql-uroot-p123456

既然能正常进入mysql的控制台，但不能正常连接mysql，那么我们再次设置密码，我参考了以下链接：http://dev.mysql.com/doc/refman/5.6/en/set-password.html

发现以前那种修改密码的方法不可用，只有SETPASSWORD=PASSWORD('123456')能有效：

Type'help;'or'\h'forhelp.Type'\c'toclearthecurrentinputstatement.

于是再次测试能否通过连接，结果成功连上mysql数据库，如下：

OperationalError:(1862,'Yourpasswordhasexpired.Tologinyoumustchangeitusingaclientthatsupportsexpiredpasswords.')
>>>cursor=connection.cursor()
>>>

3.若window下出现这种情况

若window下出现这种情况，则到mysql的安装目录下的bin目录下，执行mysql-uroot-p进入mysqlshell

OK，Enjoyit!!!
