Host IP地址 is not allowed to connect to this MySQL server

通过HeidiSQL连接MYSQL数据库报错：

SQL Error (1130): Host '192.168.1.100' is not allowed to connect to this MySQL server

说明所连接的用户帐号没有远程连接的权限，只能在本机(localhost)登录。

需更改 mysql 数据库里的 user表里的 host项
把localhost改称%

首先按下面的步骤登录Mysql服务器

mysql>use mysql;

mysql>update user set host = '%'  where user ='root';

mysql>flush privileges;

mysql>select 'host','user' from user where user='root';

mysql>quit

OK。远程连接成功！ 注意远程登录关闭防火墙
