Daemonize Rails

Daemonize Rails will configure your server to add a new daemon process for your rails app in production.

Installation

Intended for use with Debian/Ubuntu, Unicorn and Nginx

Add Daemonize Rails and Unicorn to your Rails app's Gemfile:

gem 'daemonize_rails'
gem 'unicorn'

Then run bundle:

$ bundle

Install Nginx

$ sudo apt-get install nginx

Usage

Place your Rails project in "/var/www/projectname"

Run the generator:

rails generate daemonize_rails:install

This will create your unicorn.rb and init.d file

Finally, start your app

$ /etc/init.d/myapp start
[myapp][22645]: Trying to start server...
[myapp][22668]: server started

You can also

$ /etc/init.d/myapp stop
$ /etc/init.d/myapp restart

Configure Nginx

Add the following to /etc/nginx/sites-enabled/nginx.conf

upstream <myapp> {
  server unix:/tmp/unicorn.<myapp>.sock fail_timeout=0;
}

server {
    server_name  <mydomain>.com;
    rewrite ^(.*) http://www.<mydomain>.com$1 permanent;
}

server {
  listen 80;
  server_name www.<mydomain>.com;
  root /var/www/<myapp>/public;

  location ^~ /assets/ {
    gzip_static on;
    expires max;
    add_header Cache-Control public;
  }

  try_files $uri/index.html $uri @<myapp>;
  location @<myapp> {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_pass http://<myapp>;
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 20M;
  keepalive_timeout 10;
}

Enjoy!
