远程mysql权限

最近老碰到远程mysql权限的问题

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BHost \'127.0.0.1\' is not allowed to connect to this MySQL serverConnection closed by foreign host,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,贴个解决办法:
mysql>UPDATE mysql.user SET Host=\'%\' WHERE Host=\'localhost\';
mysql>GRANT ALL PRIVILEGES
