【原】自己动手实现动态外网ip管理和动态DNS域名解析-陌上烟雨遥

项目背景:

在自己的电脑装了linux 虚拟机，想要在外网也能ssh到虚拟机进行开发，由于路由ip是动态ip，想到网上找一些动态dns域名解析，但是效果不大好，所以想到自己进行外网ip的管理。

想法：

用C++写一个界面客户端，随系统启动，定时访问自己的cgi，更新自己的外网ip；这个客户端能支持简单的几个操作：启动，退出，设置更新间隔，是否随系统启动等。

写一个cgi，接收client请求，并记录最新的外网ip到数据库；

写另外一个cgi，在其他地方访问能列出当前最新的外网ip，以及历史ip列表。

可以再写一个跳转cgi:jump.php,访问这个cgi能够自动跳转到最新的外网ip对应的目录。

至此，一个简单的动态ip管理和dns解析功能就完成了。

编程环境选择：

Client:C++,MFC;

Server:Php+Mysql，服务器使用sina云平台。

项目进度：

编写CGI,updateip.php?m=update&uid=实现更新外网ip到数据库。

Php中获取ip的方式：

$ip=@$REMOTE_ADDR;

echo "IP Address= $ip";

$ip=$_SERVER['REMOTE_ADDR'];

数据库设计：

Iplist:

建表：

Create table iplist(id int not null auto_increment,

Primary key(id),

uid VARCHAR(32),

ip VARCHAR(32),

updatetime datetime

)

<html>

<body>

CGi代码：

Update.php

<?php

$method = $_GET['m'];

if($method == "update"){

$ip=$_SERVER['REMOTE_ADDR'];

$uid = $_GET['uid'];

echo 'Got it:uid='.$uid.',ip='.$ip.'';

//mysql_connect($_SAE_MYSQL_HOST_M,$_SAE_MYSQL_USER, $_SAE_MYSQL_PASS) or die(mysql_error());

//mysql_select_db($_SAE_MYSQL_DB) or die(mysql_error());

// Create a MySQL table in the selected database

$mysql = new SaeMysql();

$sql = "INSERT INTO `iplist` (`id`, `uid`, `ip`, `updatetime`) VALUES (NULL, '".$uid."', '".$ip."', now());";

$mysql->runSql( $sql );

if( $mysql->errno() != 0 )

{

die( "Error:" . $mysql->errmsg() );

}

$mysql->closeDb();

}else{

$mysql = new SaeMysql();

$sql = "SELECT *

FROM `iplist`

ORDER BY `updatetime` DESC";

$data = $mysql->getData( $sql );

foreach($data as $i => $value){

echo "Record:id=".$value['id'].",uid=".$value['uid'].",ip".$value['ip'].",updatetime".$value['updatetime']."";

}

if( $mysql->errno() != 0 )

{

die( "Error:" . $mysql->errmsg() );

}

$mysql->closeDb();

}

</body>

</html>

用MFC编写一个简单的客户端，开机自动启动，定时请求服务器更新外网ip
