本站vpn自助注册源码
对于pptp vpn的架构，最流行的一种方法就是pptpd+freeradius+mysql，但是对于开源的vpn账户管理系统还是很少的，几乎为零，那些收费的管理系统价格高得吓人，今天在网上发现有人贡献出自己的自助注册VPN系统源码，随手收录一下。整个系统其实很简单，无非就是用php自己写几行代码就行了，下面就把代码贴出来：
?
配置文件config.php（主要是mysql的信息）：
<?php $dbhost = "localhost";//mysql服务器地址 $dbport = "3306";//mysql端口 $dbname = "radius";//freeradius数据库名称 $dbuser = "radius";//freeradius数据库用户 $dbpass = "123456";//数据库密码?>
?

代码vpn.php：
<?php include "config.php"; function creat_user($name,$pass) { global $dbhost,$dbname,$dbuser,$dbpass; $conn = @mysql_connect($dbhost,$dbuser,$dbpass) or die ("连接数据库错误！"); mysql_select_db($dbname,$conn); $sql = "SELECT * FROM `radcheck` WHERE username='".$name."'"; $query = mysql_query($sql,$conn); $row = mysql_fetch_row($query); if ($row[1] == $name) { echo "用户名已经存在，请选择其他用户名！"; } else { $sql = "INSERT INTO radcheck (id, username, attribute, op, value) VALUES ('', '$name', 'User-Password', '==', '$pass')"; $a = mysql_query($sql,$conn); if ($a) { echo "创建账户成功！"; } else { echo "创建账户失败！"; } } mysql_close($conn);}creat_user($_POST['username'],$_POST['pwd']);?>?
