bitsCN.com message from server: "Host 'xxx' is not allowed to connect to this MySQL server的解决 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。  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;  FLUSH   PRIVILEGES;  如果你想允许用户myuser从ip为192.168.1.6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;     FLUSH   PRIVILEGES;  如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器的dk数据库,并使用mypassword作为密码  GRANT ALL PRIVILEGES ON dk.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;  FLUSH   PRIVILEGES;  我用的第一个方法,刚开始发现不行,在网上查了一下,少执行一个语句 mysql>FLUSH RIVILEGES 使修改生效.就可以了  另外一种方法,不过我没有亲自试过的,在csdn.net上找的,可以看一下.  在安装mysql的机器上运行:     1、d:/mysql/bin/>mysql   -h   localhost   -u   root //这样应该可以进入MySQL服务器  2、mysql>GRANT   ALL   PRIVILEGES   ON   *.*   TO   'root'@'%'   WITH   GRANT   OPTION //赋予任何主机访问数据的权限  3、mysql>FLUSH   PRIVILEGES //修改生效  4、mysql>EXIT //退出MySQL服务器  这样就可以在其它任何的主机上以root身份登录啦!    作者 aichixihongshi bitsCN.com
