mysql 出现Host 'localhost' is not allowed to connect to this MySQL server 错误

MySql数据库：Host 'localhost' is not allowed to connect to this MySQL server

修改mysql的root密码后，出现Host 'localhost' is not allowed to connect to this MySQL server 错误。

 

解决办法：

 

C:\Program Files\MySQL\MySQL Server 5.5\my.ini

 

在[mysqld]下加下面两行，

 

skip-name-resolve

skip-grant-tables

 

重启mysql的windows服务
