怎么用安卓手机搭建本地代理服务器？

user  root;
worker_processes  2;
events {
    use epoll;
    worker_connections  10240;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  127.0.0.1;
        location / {
                proxy_pass http://$http_host$request_uri;
             }
        error_page   500 502 503 504  /5.html;
        location = /50x.html {
            root   html;
        }
    }
}
