Nginx 一般都是作为web服务器和反向代理服务器存在的,我们也可以把它用作一个Http代理服务器。操作很简单,只需要修改一下它的配置文件nginx.conf 添加一个Server字段。
server {
listen 8080;
location / {
proxy_pass http://$http_host$request_uri;
access_log off;
}
}
另外还需要在http字段内,用resolver指定一下DNS服务器,否则会发生 “nginx 502 bad gateway” 的错误。我采用是Google提供的DNS服务:
resolver 8.8.8.8;
修改完之后需要重启一下nginx服务器:
nginx -s reload
最后,修改一下浏览器代理设置的,访问www.ip.cn
,就能看到IP地址发生变化了。

同时使用两个代理端口的配置
