Nginx Configuration

By default Nginx creates /etc/nginx/nginx.conf file. This file contains main configuration, that we will let stay as it is now. Better we'll navigate to folder /etc/nginx/sites-available and create configuration for our example.com site. By default main configuration file reads from these folders: sites-available and sites-enabled, but the first one serves only for storing configurations but the second one contains realy executable configs. At sites-available create file example.com and fill it with something that looks like following:

upstream example {
  server 0.0.0.0:3000 max_fails=3 fail_timeout=1s;
  keepalive 4;
}


server {
  listen       80;
  server_name example.com www.example.com;

  root /home/deploy/example.com/public;

  client_max_body_size 100M;

  location / {
    proxy_pass http://example;
  }

  error_page   500 502 503 504  /50x.html;
  location = /50x.html {
      root   html;
  }
}

Here we create upstream and redirect all requests at location / to the instance of Passenger working on port 3000. Then we need to symlink our config to sites-enabled:

sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/example.com 

Don't forget to test your configuration:

sudo nginx -t

And restart service if config is OK:

sudo service nginx restart
