 4 | 由于家里路由器公网ip老是变动，
 5 | 于是有了这个想法，
 6 | 通过有公网ip的服务器作为dns服务器，
 7 | 把域名解析到家里的电脑ip
 8 | 
 9 | 
10 | > 这只是穷B不买域名只改设备dns自嗨的一种方式
11 | 
12 | 
13 | 目前跑脚本系统最好用Linux，Windows我没测过
14 | 
15 | 安卓手机改DNS时需要在wifi里把ip设置为静态（小米手机好恶心，我改了dns对小米广告域名的ip映射，还是有广告。。。）
16 | 
17 | ```
18 | 
19 | 1. 命令行 cli 运行 `sudo php cliDaemon.php` 守护进程来作为dns服务器
20 | 
21 | 2. 家里的电脑浏览器访问`<公网dns服务器的ip>/index.php?fakeDomain=my-home-domain.com&ip=118.89.204.190`
22 | 来更新我自己的假域名与家里变动ip的对应映射关系
23 | 
24 | 3. 手机等想访问家里电脑的设备的dns地址添加这个dns服务器ip
25 | 
26 | ```
