How to install Ruby on Rails on Debian 10 Buster?

Ruby is one of those programming languages that may be a little underestimated. However, it is a robust, multipurpose, open-source language that stands out for its efficiency in coding applications. Part of its popularity lies in the Ruby on Rails framework with which professional web applications can be made with relative ease. So, in this post, you will learn how to install Ruby on Rails on Debian 10.

Ruby on Rails makes Ruby more popular

The truth is that Ruby is still widely used today, but when compared to Python, PHP or Java is far behind. So it is no wonder it is not so easy to learn.

However, thanks to the efficiency of Ruby on Rails, many people have turned their eyes back to this language. Ruby on Rails is a fairly robust framework for creating web applications.

Some of the highlights of Ruby on Rails are as follows:

  • It uses many configuration conventions. This makes the framework, once installed, ready to work.
  • In Rails, there are several ways to do a certain thing. That is, it makes collaboration easier and the code easier to understand.
  • With Ruby on Rails, you’ll have a framework that uses the DRY (Don’t Repeat Yourself) principle. With this, duplicity is eliminated and it makes it very agile.
  • Open Source, so licensing should not be a problem for you.

If we add a robust and stable operating system like Debian to Ruby on Rails, then we have a great combination. So, let us start.

In case you do not have sudo enabled, I recommend you read our post about it.

Now, you need to download the GPG key to install RVM (Ruby Version Manager) and then install Ruby.

:~$ curl -sSL https://rvm.io/mpapis.asc | sudo gpg --import -
:~$ curl -sSL https://rvm.io/pkuczynski.asc | sudo gpg --import -

Then, download the RVM script.

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

Note: you can run bundle install command to install all gem missed. After that, run rails s command again.

Also, you can specify an IP address and port.

:~# rails server --binding [Ip_address] --port [Port]

Finally, open your web browser and go to http://SERVER-IP:3000 and you will see this.
