How To Install Rails and Nginx with Passenger on Ubuntu

<div dir="ltr" style="text-align: left;" trbidi="on">

<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>

<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>
<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
</span><span style="color: lime;"># source /usr/local/rvm/scripts/rvm</span></span></span></pre>
</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>
<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;"># </span><span style="color: lime;">rvmsudo passenger</span><span style="color: white;">-install-nginx-module</span></span></span></pre>
</div>
<div>
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">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.</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;">Now we need to configure <a href="http://www.hackthesec.co.in/search/label/NGINX">nginx</a> to “talk” to Passenger. In order to do that, we need to open the nginx configuration file (<b>/opt/nginx/conf/nginx.conf</b>), using our favorite editor and add the following:</span></span></div>

</div>
<div>
<span style="color: #222222; font-family: Verdana, Geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Once that is that, we should go to our directory (in this case it is <b>/var/www/rails_app/public</b>) and create the application. After all this is installed and configured, we simply need to start Nginx.</span></span></div>

In contrast to other web accelerators, such as Squid, which began life as a client-side cache, or Apache and nginx, which are primarily origin servers, Varnish was designed as an HTTP accelerator. Varnish is focused exclusively on HTTP, unlike other proxy servers that often support FTP, SMTP and other network protocols.</span></div>

<span style="font-family: "georgia" , "times new roman" , serif;">Before we install Varnish, we should have <a href="http://www.hackthesec.co.in/search/label/Apache" target="_blank">apache </a>already installed. To install Apache, we should simple execute:</span></div>

<span style="font-family: "georgia" , "times new roman" , serif;">Varnish should be available for install in the standard <a href="http://www.hackthesec.co.in/search/label/Ubuntu" target="_blank">Ubuntu </a>repositories. However, before we uninstall it we need to make sure that we are going to import the correct and latest varnish repository. We will start with importing their key:</span></div>

<span style="font-family: "georgia" , "times new roman" , serif;">We need make sure that our repositories are up-to-date. After then, we are ready to install Varnish.</span></div>

<span style="font-family: "georgia" , "times new roman" , serif;">Once we have Varnish installed, we should setup some basic configuration parameters. By default, Varnish will listen on port 80, so we need to edit Apache configuration and set apache to listen on different port. In order to change that port that Apache listens on another port, we should open the<code style="background-color: #f9f2f4; border-radius: 4px; box-sizing: border-box; font-size: 16.2px; padding: 2px 4px;"><span style="color: red;">/etc/apache2/ports.conf</span></code> file and edit as follows:</span></div>

<span style="font-family: "georgia" , "times new roman" , serif;">Then, we should also make changes in the default virtual host file (and in every other virtual host file that exists):</span></div>

<span style="font-family: "georgia" , "times new roman" , serif;">In order to set varnish parameters, we should open the default Varnish configuration file,<code style="background-color: #f9f2f4; border-radius: 4px; box-sizing: border-box; font-size: 16.2px; padding: 2px 4px;"><span style="color: red;">/etc/default/varnish</span></code>, using our favorite editor, and uncomment the following directive:</span></div>

<span style="font-family: "georgia" , "times new roman" , serif;">Please note that in 8080 is the port on which Apache listens. If we choose another port for Apache to listen on, that we should use that port number instead. We are done with the basic configuration. Next, we need to restart the services and all traffic will go through Varnish:</span></div>
