In this tutorial, we will show you how to install and configuration of Ruby on Rails on your Ubuntu 16.04 server. For those of you who didn’t know, Ruby on Rails (RoR) is a framework written in the Ruby programming language that allows you to use Ruby in combination with HTML, CSS, and similar programming languages. It is used by many developers since it makes application development very simple.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘
sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of Ruby on Rails on a Ubuntu 16.04 (Xenial Xerus) server.
Install Ruby on Rails on Ubuntu 16.04
Step 1. First, make sure that all your system packages are up-to-date by running the following
apt-get commands in the terminal.
sudo apt-get update sudo apt-get upgrade
Step 2. Installing RVM.
One way of installing Ruby on Rails on a VPS is by using the Ruby enVironment Manager, or shortly RVM. We will use RVM to install Ruby on Rails in this tutorial. In order to install RVM on your server, you can use the following commands:
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 cd /tmp && \curl -sSL https://get.rvm.io -o rvm.sh cat /tmp/rvm.sh | bash -s stable
To start using RVM you need to run:
If, for some reason, you need or want a different version of Ruby, you can check which ones are available easily in RVM:
rvm list known
The list result should look like the following one:
# MRI Rubies [ruby-] 1.8.6 [-p420] [ruby-] 1.8.7 [-head] # security released on head [ruby-] 1.9.1 [-p431] [ruby-] 1.9.2 [-p330] [ruby-] 1.9.3 [-p551] [ruby-] 2.0.0 [-p648] [ruby-] 2.1 [.8] [ruby-] 2.2 [.4] [ruby-] 2.3 [.0] [ruby-] 2.2-head ruby-head ...
To install a different version of Ruby, just find the version number that you want and tell RVM to install it:
rvm install 2.3.0 rvm use 2.3.0
Step 3. Installing Rails.
Now that RVM is installed and configured and Ruby is on the system, you can install Rails. Rails is available as a Gem, which is a Ruby package. When Ruby is installed, its native Gem packaging system is also installed. Installing Ruby packages is very similar to any Linux package manager. To install Rails you can use the command below:
gem install rails
Or, run the following command to install a particular version of rails:
gem install rails -v 5.0.0
To verify the installation as well as to check what version of Rail you are currently using, you can use the command:
# rails -v Rails 220.127.116.11
Now you are ready to start with your first Ruby on Rails project. Create a new Ruby on Rails application in your home directory:
cd ~ rails new idrootApp
This should take no longer than a minute. Once your new Ruby on Rails application is created, you can start developing the application. There are new guides for Rails 5.0 which will help you understand how all of the pieces fit together.
Congratulations! You have successfully installed Ruby on Rails. Thanks for using this tutorial for installing Ruby on Rails in Ubuntu 16.04 (Xenial Xerus) systems. For additional help or useful information, we recommend you to check the official Ruby on Rails website.
