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，最近很多网友都在问本站的vpn是如何架设的，尤其是那个自助注册的，其实很简单，无非就是用php自己写几行代码就行了，下面我就把我的那几行代码贴出来：
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']);
?>
然后就是用html写个注册表单index.html：
<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<meta http-equiv="expires" content="0">
