mysql Host 'microsof-80f25e' is not allowed to connect to this MySQL server

机器重新安装系统后，之前好好的项目运行项目报错：Host '主机名' is not allowed to connect to this MySQL server

控制台信息如下：

[2013-08-20 16:13:00 750][WARN](org.hibernate.util.JDBCExceptionReporter.logExceptions(JDBCExceptionReporter.java:77)) SQL Error: 0, SQLState: null

系统中我用的是root账号，也就是root用户没有远程访问主机的缘故(当初安装Mysql时，没有勾选Enable root access from remote machines)

如下图所示：



解决方法1：打开mysql的实例配置向导：MySQL Server Instance Config Wizard，勾选Enable root access from remote machines即可。

解决方法2：修改root权限，让root用户拥有远程访问的权限：

//赋予root访问
任何主机
数据的权限

(1)GRANT

ALL

PRIVILEGES

ON

*.*

TO

'root'

@

'%'

WITH

GRANT

OPTION

//使修改配置生效

(2)

FLUSH

PRIVILEGES

PS:第二种方式没有效果的话，重启动下机器。
