Making production on port 80 and development on any other

Go to /etc/nginx/conf.d delete all files in it and create two files MyAppDevelopment.conf and MyAppProduction.conf (change MyApp to your app name).

Add to MyAppDevelopment.conf:

upstream MyAppDevelopment {
  server              unix:///tmp/MyAppDevelopment.sock;
}

server {
  listen              54321;
  server_name         site.com *.site.com;

  access_log          /var/log/nginx/myapp-access.log;

  location / {
    root              /home/luna/www/myapp/public;
    try_files         $uri @app;
    gzip_static       on;
    expires           max;
    add_header        Cache-Control public;
  }

  location @app {
    proxy_pass        http://MyAppDevelopment;
    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_redirect    off;
    proxy_next_upstream error timeout invalid_header http_502;
    proxy_max_temp_file_size 0;
  }
}

Add to MyAppProduction.conf:

upstream MyAppProduction {
  server              unix:///tmp/MyAppProduction.sock;
}

server {
  listen              localhost:8080;

  access_log          /var/log/nginx/myapp-access.log;

  location / {
    root              /home/luna/www/myapp/public;
    try_files         $uri @app;
    gzip_static       on;
    expires           max;
    add_header        Cache-Control public;
  }

  location @app {
    proxy_pass        http://MyAppProduction;
    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_redirect    off;
    proxy_next_upstream error timeout invalid_header http_502;
    proxy_max_temp_file_size 0;
  }
}

(no you can't join similar settings)

In /etc/nginx/nginx.conf add:

gzip  on;

# Default server
server {
  listen              8080 default_server;
  listen              54321 default_server;
  return 404;
}

include /etc/nginx/conf.d/*.conf;

Then start servers:

bundle exec puma -e development -b unix:///tmp/MyAppDevelopment.sock --debug
bundle exec puma -e production -b unix:///tmp/MyAppProduction.sock

Or in background:

bundle exec puma -e development -db unix:///tmp/MyAppDevelopment.sock
bundle exec puma -e production -db unix:///tmp/MyAppProduction.sock
