HOSt ip is not allowed to connect to this MySql server

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 -pvmwaremysql>use mysql;

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

mysql>flush privileges;

mysql>select host, user from user;
