• nginx
  /etc/nginx/sites-available/下的default文件

server {
        listen   80; ## listen for ipv4; this line is default and implied
        ...
        location / {
                proxy_pass http://127.0.0.1:8000;
                proxy_set_header Host $host;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
