ERROR 1130: Host '192.168.1.3' is not allowed to connect to this MySQL

当使用Mysql帐号远程登陆的时候，出现类似如下错误：
ERROR 1130: Host ‘192.168.1.3‘ is not allowed to connect to this MySQL

解决办法：

1. 改表法(可能是你的帐号不允许从远程登陆，只能在localhost。这个时候只要在localhost的那台电脑，登入mysql后，更改 "mysql" 数据库里的 "user" 表里的 "host" 项，从"localhost"改称"%")

c:/mysql/mysql server 5.1>mysql -u root -p

输入相应密码

mysql>use mysql;

mysql>show tables; (确认一下表user是否存在)

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

mysql>quit

退出mysql

c:/mysql/mysql server 5.1>net stop mysql

c:/mysql/mysql server 5.1>net start mysql

现在远程连接这部mysql服务器就行了

c:/mysql/mysql server 5.1>mysql -h 192.168.1.3 -u root -p

2. 授权法
例如，你想myuser使用mypassword从任何主机连接到mysql服务器的话。

GRANT ALL PRIVILEGES ON *.* TO ‘myuser‘@‘%‘ IDENTIFIED BY ‘mypassword‘ WITH GRANT OPTION;
如果你想允许用户myuser从ip为192.168.1.3的主机连接到mysql服务器，并使用mypassword作为密码
GRANT ALL PRIVILEGES ON *.* TO ‘myuser‘@‘192.168.1.3‘ IDENTIFIED BY ‘mypassword‘ WITH GRANT OPTION;

ERROR 1130: Host '192.168.1.3' is not allowed to connect to this MySQL
