<div>
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><b>Ruby on Rails</b> 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.</span></span></div>
<div>
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><br /></span></span></div>
<div>
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">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 <a href="http://www.hackthesec.co.in/search/label/NGINX">Nginx</a>. Nginx is fast <a href="http://www.hackthesec.co.in/search/label/web_server">webserver</a> with a strong focus on high concurrency, high performance and low memory usage.</span></span></div>

<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Before we proceed with installation, we should make sure that our system repositories are up to date:</span></span><span style="background-color: white; color: #222222; font-family: Verdana, Geneva, sans-serif; font-size: 15px; line-height: 26px;">.</span></div>

<div>
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">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:</span></span></div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: large;"><span style="line-height: 15.6px;"><span style="color: white;"># curl -L get.rvm.io | bash -s stable

</div>
<div>
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">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:</span></span></div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: large;"><span style="line-height: 15.6px;"><span style="color: white;"># rvm </span><span style="color: lime;">requirements</span><span style="color: white;">

</div>
<div>
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif; font-size: 15px; line-height: 26px;">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.</span></div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: large;"><span style="line-height: 15.6px;"><span style="color: white;"># rvm </span><span style="color: orange;">install 1.9.3</span><span style="color: white;">
# rvm </span><span style="color: lime;">use 1.9.3 --default</span></span></span></pre>
</div>
<div>
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">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:</span></span></div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: large;"><span style="line-height: 15.6px;"><span style="color: white;"># rvm rubygems current
</span><span style="color: lime;"># gem install rails</span></span></span></pre>
</div>
<div>
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">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:</span></span></div>
<div>
<pre style="background-attachment: scroll; background-clip: initial; background-color: #3c3c3c; background-image: none; background-origin: initial; background-position: 0px 0px; background-repeat: repeat; background-size: initial; border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="line-height: 15.6px;"><span style="font-size: large;"><span style="color: white;"># gem install </span><span style="color: lime;">passenger</span></span><span style="color: white;">
</span></span></pre>
</div>
<div>
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif; font-size: 15px; line-height: 26px;">Once passenger is installed, the rest of the required setup is fully automated. We execute the command:</span></div>
