最近有几个人问我相同问题,安装了mysql，然后用 telnet ip 3306,端口后报
Host '192.168.1.163' is not allowed to connect to this MySQL serverConnection closed by foreign ,虽然自己以前也碰到过，后来解决了,但是觉得还是值得贴出来,估计会有很多人同样碰到过,
解决办法:
mysql>UPDATE mysql.user SET Host='%' WHERE Host='localhost';
mysql>GRANT ALL PRIVILEGES ON *.* TO root@"%" ;
mysql>FLUSH PRIVILEGES;
