Sure, VirtualBox is a popular solution for quick and easy virtualization on Linux, but KVM can provide a more robust and efficient solution with minimal configuration. With the use of tools like Virt-Manager, it can be just as easy to use. Ubuntu 16.04 running in a virtual machine

Nginx is quickly overtaking Apache as the favorite web server. For web apps built in languages like Rails and Python it’s virtually ubiquitous, but it’s a bit slower to catch on in the PHP world. Part of the reason for that is how easily PHP and Apache go together. However, PHP and Nginx can cooperate nearly as easily, and with the release of PHP 7, combining the two can be a fairly speedy option.

The Packages

First thing’s first. Update Ubuntu and get the the Nginx and PHP packages.

# sudo apt-get update && sudo apt-get -y upgrade
# sudo apt-get -y install nginx php7.0 php7.0-fpm

When the installation is finished, the packages should all be in place, and actually running. To make sure that this is the case, you can check that both Nginx and the PHP-FPM services are running in Systemd.

# sudo systemctl status nginx
# sudo systemctl status php7.0-fpm

If Systemd confirms that both services are running, the server should actually be up, and you should be able to see the default Nginx welcome page by navigating to localhost in the browser.

Ruby on Rails is one of the most popular web development platforms today, with some of the hottest start-ups and tech giants employing it in their software stacks. One of the biggest selling points of Ruby on Rails is the ease of development. It is just as easy to get set up and start developing, especially on Linux.

Installing the Packages

There are a couple of packages needed before Ruby can be installed in set up, and no, Ruby isn’t one of them. Since this tutorial is going to be using the Ruby Version Manager, or RVM, to manage Ruby, there’s no need to install the package through Ubuntu. There are a couple of packages that RVM needs in order to work and one that never seems to get pulled in by gem installs(nodejs).

# sudo apt-get install build-essential curl nodejs
