How To Install Ruby on Rails on Debian 10

Install Ruby on Rails on Debian 10

In this tutorial, we will show you how to install Ruby on Rails on Debian 10. For those of you who didn’t know, Ruby on Rails (RoR) is a web application framework based on the Ruby programming language. It is a server-side MVC (Model-View-Controller) framework that provides default structures for a database, an internet service, and sites. It allows you to use Ruby in combination with HTML, CSS, and similar programming languages.

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 Debian 10 (Buster).

Install Ruby on Rails on Debian 10 Buster

Step 1. Before running the tutorial below, it’s important to make sure your system is up to date by running the following apt commands in the terminal:

sudo apt update
sudo apt install gnupg2

Step 2. Installing Dependencies.

Now we install all dependencies using the following command below:

sudo apt install curl nodejs dirmngr gnupg2 build-essential libssl-dev git-core zlib1g-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev software-properties-common libxslt1-dev libcurl4-openssl-dev libffi-dev

Step 3. Installing Yarn.

Now add the Yarn repository to install the Yarn package manager:

curl -sS | apt-key add -
echo "deb stable main" | tee /etc/apt/sources.list.d/yarn.list

Once done, Install Yarn using the below command:

sudo apt update
sudo apt install yarn

Step 4. Installing Ruby Using rbenv.

The rbenv lets you install and manage the versions of Ruby easily, and it is simpler than RVM. First, download the rbenv from the Git repository using the following command:

git clone ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL

git clone ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL

Next, install the Ruby version 2.7.0 using the following command:

rbenv install 2.7.0

Then, set the Ruby version 2.7.0 for all user with the following command:

rbenv global 2.7.0

Check the Ruby version:

ruby -v

Next, install the bundler with the following command:

gem install bundler

Step 5. Installing Ruby on Rails on Debian 10.

At this point, Ruby is installed in your system. Now, run the command below to install the latest version of Rails:

gem install rails

Check the Rails version:

rails -v

Step 6. Create a Test Application.

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 idrootApps

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 that 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 the latest version of Ruby on Rails on the Debian system. For additional help or useful information, we recommend you check the official Ruby on Rails website.
