nginx redirect ip to domain name

Question

I am trying to deploy a website with nginx and gunicorn. Nginx is serving static files and acting as a proxy to gunicorn.

Here is the content of my /etc/nginx/sites-available/herbop file

server {
       listen 80;
       server_name herbop.com;

       location / {
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto $scheme;
                proxy_set_header Host $http_host;
                proxy_intercept_errors on;
                proxy_pass http://127.0.0.1:8001;
       }

       location /static/ {
                autoindex on;
                alias /opt/Herbop-Backend/app/static/;
       }
}

server {
       listen 80;
       server_name 51.254.123.234;
       return 301 $scheme://herbop.com$request_uri;
}

In this case I seem to get an infinite redirection loop.

Any idea ?

Answer 1

• DNS: Point herbop.com using an A record to 51.254.123.234. (Remove the existing http redirect.) (Note: DNS is distributed, sometimes it takes some time to propagate.)

• Try the following nginx config:

  server {
      listen 80;
      server_name herbop.com;
  
      location /static/ {
          root /opt/Herbop-Backend/app;
      }
  
      location / {
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header X-Forwarded-Proto $scheme;
          proxy_set_header Host $http_host;
          proxy_intercept_errors on;
          proxy_pass http://127.0.0.1:8001;
      }
  }
  
  server {
      listen 80;
      server_name 51.254.123.234;
      return 301 $scheme://herbop.com$request_uri;
  }
  

  • Notes:

    • ((If all you want to do is serving static files to visitors, like images etc., which are embedded into your *.html, you don't need autoindex. "The ngx_http_autoindex_module processes requests ending with the slash character (‘/’) and produces a directory listing.[...]" As far as I understand, you won't need this, so don't enable it.)) ((Not sure if I got you right, and of which kind your static files are.))

    • Regarding your alias directive: According to the docs: "When location matches the last part of the directive’s value:

      location /images/ {
           alias /data/w3/images/;
      }
      

      it's better to use the root directive instead":

      location /images/ {
           root /data/w3;
      }
