How To Install Ruby on Rails on Debian 11

Install Ruby on Rails on Debian 11

In this tutorial, we will show you how to install Ruby on Rails on Debian 11. For those of you who didn’t know, Ruby on Rails is a free, open-source, and one of the most popular application stacks used for creating sites and web apps. It is written in Ruby programming language and follows the MVC (Model-View-Controller) concept.

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 the GIMP open-source image editor on a Debian 11 (Bullseye).

Install Ruby on Rails on Debian 11 Bullseye

Step 1. Before we install any software, 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 upgrade
sudo apt install gnupg2 curl wget gcc g++ make

Step 2. Installing RVM.

By default, RVM is not available from the default Ubuntu base repository. Now run the following command below to add the RVM repository and import the GPG key:

gpg2 --keyserver hkp://pool.sks-keyservers.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
curl -sSL https://rvm.io/pkuczynski.asc | gpg2 --import -

After that, download and run the RVM installation script:

curl -sSL https://get.rvm.io | bash -s stable --ruby

Next, load the RVM system path using the following command:

source /usr/local/rvm/scripts/rvm

Verify the RVM installation version:

rvm version

Step 3. Installing Ruby using RVM.

Ruby package is available in the default Debian repositories. First, we update RVM to the latest version by issuing a command:

rvm get stable --autolibs=enable

Next, add the root user to the RVM group so that the root user can run the RVM command.:

usermod -a -G rvm root

Then, install the latest version of Ruby using the following command below:

rvm install ruby-3.0.2
rvm --default use ruby-3.0.2

You can confirm installation by issuing the below command:

ruby --version

Step 4. Installing Nodejs and Yarn.

By default, Nodejs is not available on the Debian 11 base repository. Now we add the Node source repository using the following command:

curl -sL https://deb.nodesource.com/setup_14.x | bash -

Next, run the following command to add the Yarn repository:

curl -sL https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list

After that, update the apt repository and install Nodejs and Yarn packages using the following command below:

sudo apt update
sudo apt install nodejs yarn

Verify the Nodejs version:

node --version

Verify the Yarn version:

yarn --version

Step 5. Installing Ruby on Rails on Debian 11.

First, run the following command to update the RubyGem to the latest version:

gem update --system

Next, we install the latest version of Ruby on Rails using the RubyGem command below:

gem install rails -v 6.1.4

Verify the installed version of Rails using the following command:

rails -v

Step 6. Create a Test Application.

Now we create a new project using Rails:

rails new project
cd project

After that, start the puma rails web server using the command below:

rails s -b 192.168.77.21 -p 8080

Output:

=> Booting Puma
=> Rails 6.1.4.1 application starting in development 
=> Run `bin/rails server --help` for more startup options
Puma starting in single mode...
* Puma version: 5.5.2 (ruby 3.0.2-p107) ("Zawgyi")
*  Min threads: 5
*  Max threads: 5
*  Environment: development
*          PID: 46462
* Listening on http://192.168.77.21:8080
Use Ctrl-C to stop

Once successfully create a new project, now access it using the URL http://your-server-ip-address:8080. You should see the Rails default page:
