How To Install Rails Nginx with Passenger on
Ubuntu

• Ruby on Rails is an open source web application
  framework which runs on the Ruby programming
  language.
• It allows the developers creating pages and
  applications that gather information from the web
  server, talk to or query the database, and render
  templates out of the box directly to the internet
  browsers.
• As a result, Rails features a routing system that
  is independent of the web server.
• The web server is used to render the content
  only.
• The choice for that would be Nginx.
• Nginx is fast webserver with a strong focus on
  high concurrency, high performance and low memory
  usage.

• Before we proceed with installation, we should
  make sure that our system repositories are up to
  date
• sudo apt-get update
• Once we are up to date with the latest available
  packages, the next step is to install Ruby
  Version Manager.
• It is application that allows to manage several
  different ruby versions easily, we can install
  RVM and then load it with
• curl -L get.rvm.io bash -s stable source
  /usr/local/rvm/scripts/rvm

• We must make sure that we have all dependencies
  from RVM.
• To make sure that we have all required
  dependencies, we execute the following command
• rvm requirements
• It will make sure that we are up to date and
  install the missing requirements (if any).
• Once we have RVM installed and configured, we can
  proceed to install and configure Ruby.
• rvm install 1.9.3 rvm use 1.9.3 --default

• These two commands will install Ruby and set the
  system to use version 1.9.3 by default.
• The next step is to make sure we have all
  components for Ruby on Rails.
• Ruby Gems is a package manager for the Ruby
  programming language that provides a standard
  format for distributing Ruby programs and
  libraries, a tool designed to easily manage the
  installation of gems, and a server for
  distributing them, we can install it with this
  command and then use it to install Rails
• rvm rubygems current gem install rails

• This process could take some time, but after it
  finish, Ruby on Rails is installed.
• Next, we need to make sure that we can easily
  deploy Ruby on rails to any web server.
• We will install and use Passenger for that. It
  will serve as interface or bridge for
  communication between Ruby and the web server,
  you can install it with the following command
• gem install passenger
• Once passenger is installed, the rest of the
  required setup is fully automated. We execute the
  command
• rvmsudo passenger-install-nginx-module

• Once we do this, it checks for all dependencies
  automatically and install those that are missing.
  
• If some manual user action is required, Passenger
  will tell us, as well as give us detailed
  instructions how to do it.
• Now we need to configure nginx to talk to
  Passenger.
• In order to do that, we need to open the nginx
  configuration file (/opt/nginx/conf/nginx.conf),
  using our favorite editor and add the following
• server listen 80 server_name
  example.com passenger_enabled on root
  /var/www/rails_app/public

• In order to create our rails app, we need to
  install Node.js first
• sudo apt-get install nodejs
• Once that is that, we should go to our directory
  (in this case it is /var/www/rails_app/public)
  and create the application. After all this is
  installed and configured, we simply need to start
  Nginx.
• rails new my_first_rails_app sudo service
  nginx start
• We can try and access our new Ruby on Rails
  application using our browser.
• It seems that it was much easier to setup the
  environment and create our first Ruby on Rails
  project than we thought, was it?
