Nginx - How to serve rails app on subdomain and static html on domain?

Nginx Getting Started Configuration Management Ubuntu

Hi there!

I have successfully deployed a doplet using ubuntu + rails + nginx + unicorn. Everything is up and running.

Ideally I would like app.mydomain.com to run my ruby application and mydomain.com to serve static html content. Is that something that's possible with nginx?

Thanks!
Alex

That's definitely possible. You'll just need to define a new server block in your Nginx configuration, pointing to the directory holding the static files. You also need to set server_name for each block so Nginx knows how to direct the requests.

Here's an example:

  • upstream app_server { server 127.0.0.1:8080 fail_timeout=0; }
  • server {
  • listen 80;
  • root /home/rails/public;
  • server_name app.mydomain.com;
  • index index.htm index.html;
  • location / {
  • try_files $uri/index.html $uri.html $uri @app;
  • }
  • location ~* ^.+\.(jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|mp3|flv|mpeg|avi)$ {
  • try_files $uri @app;
  • }
  • location @app {
  • proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  • proxy_set_header Host $http_host;
  • proxy_redirect off;
  • proxy_pass http://app_server;
  • }
  • }
  • server {
  • listen 80;
  • root /var/www/html;
  • server_name mydomain.com;
  • index index.htm index.html;
  • location / {
  • try_files $uri $uri/ =404;
  • }
  • error_page 404 /404.html;
  • error_page 500 502 503 504 /50x.html;
  • location = /50x.html {
  • root /usr/share/nginx/html;
  • }
  • }

Nginx is an incredibly powerful web server and reverse proxy. In this guide, we'll discuss how to set up server blocks on Ubuntu 14.04 in order to server multiple domains from a single server.
