Mysql:is not allowed to connect to this MySQL server

如果你想连接你的mysql的时候发生这个错误:

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

解决方法:
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"改成"%"。

mysql -u root -p 密码
mysql>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;

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 'root'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'10.10.40.54' IDENTIFIED BY '123456' WITH GRANT OPTION;
