How to Install Ruby on Rails on Ubuntu 24.04
Introduction
Install Ruby on Rails on Ubuntu 24.04 to develop scalable and maintainable web applications with ease. Ruby on Rails is a robust web application framework that utilizes the Model-View-Controller (MVC) architecture and adheres to the principle of convention over configuration, minimizing repetitive setup tasks by enforcing standard coding and file organization practices.
Ruby on Rails also integrates with custom tools for tasks such as database migrations and asset management with a wide range of community-developed libraries to run production-ready applications.
The article explains how to install Ruby on Rails on Ubuntu 24.04 and set up a development environment to run web applications.
Install Mise and Required Dependencies for Ruby
Mise is a Ruby version manager used to install and manage packages in Ruby environments. It offers a simplified setup process, enabling you to switch between Ruby versions without complex configurations. Ruby requires a set of dependencies that include essential libraries for encryption, file compression, and other critical functionalities to run applications. Follow the steps below to install Mise and all required dependency packages for Ruby.

config/routes.rbfile to enableHome#indexas the default route.RUBYSave and close the file.
Start the Rails server again to load the application.
CONSOLEAccess port
3000using your server's IP address in a new web browser window and verify that aGreetings from Vultrmessage displays.
Conclusion
You have installed Ruby on Rails on Ubuntu 24.04 and run a sample application on the server. You can run Rails as a system service and set up a reverse proxy such as Nginx to securely deliver web applications using a domain on your server.
