host not allowed to connect to this MySQL server

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”%” mysql -u root -pvmwaremysql>use mysql;mysql>update user set host = ‘%’ where user = ‘root’;mysql>select host, user from user;

 

2.授权法

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;
