Are you looking to develop web applications using Ruby on Rails on your CentOS 8 server? Ruby on Rails is a popular web framework that allows developers to create powerful and dynamic web applications with ease. In this guide, we will walk you through the steps to install Ruby on Rails on CentOS 8.

Step 1: Update and Upgrade Your System

Before we begin the installation process, it is always a good idea to update and upgrade your system to ensure that you have the latest packages and security patches installed. You can do this by running the following commands:

sudo yum update
sudo yum upgrade

Step 2: Install Ruby Version Manager (RVM)

RVM is a tool that allows you to easily install and manage multiple versions of Ruby on your system. To install RVM, you can use the following command:

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

After the installation is complete, you will need to source the RVM scripts to your shell to use it. You can do this by running the following command:

source /etc/profile.d/rvm.sh

Step 3: Install Ruby

Once RVM is installed, you can install the desired version of Ruby using the following command (replace ruby_version with the version of Ruby you want to install):

rvm install ruby_version

After the installation is complete, you can set the newly installed Ruby version as the default by running the following command:

rvm use ruby_version --default

Step 4: Install RubyGems and Bundler

RubyGems is a package manager for Ruby that allows you to easily install and manage Ruby libraries and applications. You can install RubyGems by running the following command:

gem install rubygems

Bundler is a dependency manager for Ruby that helps you manage your application’s dependencies. You can install Bundler by running the following command:

gem install bundler

Step 5: Install Rails

With Ruby and the necessary tools installed, you can now install Ruby on Rails using the following command:

gem install rails

After the installation is complete, you can verify the installation by running the following command:

rails -v

This should display the installed version of Rails on your system.

Congratulations! You have successfully installed Ruby on Rails on your CentOS 8 server. You are now ready to start developing web applications using this powerful web framework. If you encounter any issues during the installation process, feel free to reach out to our support team for assistance.
