To setup production environment with ruby, rails, nginx and passengeruse following steps one by one

• Install dev dependencies

  
        sudo apt-get install zlib1g zlib1g-dbg zlib1g-dev sqlite3 libsqlite3-dev build-essential openssl libreadline6 libreadline6-dev curl git-core libssl-dev libyaml-dev libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion g++ openjdk-6-jdk git nodejs
      

• Install rvm with latest stable ruby version

  
        curl -L https://get.rvm.io | bash -s stable --ruby
      

• Edit .bash_profile file and add following file then press Ctrl-D if you are using cat

  
        cat >>~/.bash_profile
        [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"
        Ctrl+D
      

• Latest rubygems

  
        rvm rubygems latest
      

• Install Rails you can provide versions

  
        sudo gem install rails
      

• Install postgres

  
        sudo apt-get -y install postgresql libpq-dev
      

• Installation of Git

  
        sudo apt-get install git
        sudo apt-get update
        which git
        sudo apt-get install git-core
        which git
        git --version
      

• Git Configuration

  
        git config --global user.name "vishalzambre"
        git config --global user.email v.zambre@gmail.com
        git config –list
      

• Installation of Nginx

  
        sudo apt-get -y update
        sudo apt-get -y install build-essential zlib1g-dev libssl-dev libreadline-dev libyaml-dev libcurl4-openssl-dev curl git-core python-software-properties
      

• Installation of passenger

  
        gem install passenger
        rvmsudo passenger-install-nginx-module
  
        NOTE: Choose "download, compile, and install Nginx for me"
        Accept defaults for any other questions it asks you
      

• Next we want to setup a script to allow us to control Nginx

  
        wget -O init-deb.sh http://library.linode.com/assets/660-init-deb.sh
        sudo mv init-deb.sh /etc/init.d/nginx
        sudo chmod +x /etc/init.d/nginx
        sudo /usr/sbin/update-rc.d -f nginx defaults
      

• You can now control Nginx with this script. To start and stop the server manually, you run:

  
        sudo /etc/init.d/nginx stop
        sudo /etc/init.d/nginx start
        We can verify nginx is running by opening up Firefox and going to http://localhost
      

• Node.js for the Rails asset pipeline

  
        sudo apt-add-repository ppa:chris-lea/node.js
        sudo apt-get -y update
        sudo apt-get -y install nodejs
      

• Configure Your Rails App

  
        You can modify your /opt/nginx/conf/nginx.conf
        server {
            listen 80;
            server_name example.com;
            root /home/deploy/myapplication/public;   # <--- be sure to point to 'public'!
            passenger_enabled on;
        }
        Just change the application folder name and the server name and then restart the nginx service.
