Guides - Deploy Ruby on Rails through the Linode Marketplace
Quickly deploy a Compute Instance with many various software applications pre-installed and ready to use.
Ruby on Rails is a server-side web application framework that allows web designers and developers to implement dynamic, fully featured web applications.
The Linode Marketplace allows you to easily deploy software on a Compute Instance using the Cloud Manager. See Get Started with Marketplace Apps for complete steps.
Log in to the Cloud Manager and select the Marketplace link from the left navigation menu. This displays the Linode Create page with the Marketplace tab pre-selected.
Under the Select App section, select the app you would like to deploy.
Complete the form by following the steps and advice within the Creating a Compute Instance guide. Depending on the Marketplace App you selected, there may be additional configuration options available. See the Configuration Options section below for compatible distributions, recommended plans, and any additional configuration options available for this Marketplace App.
Click the Create Linode button. Once the Compute Instance has been provisioned and has fully powered on, wait for the software installation to complete. If the instance is powered off or restarted before this time, the software installation will likely fail.
To verify that the app has been fully installed, see Get Started with Marketplace Apps > Verify Installation. Once installed, follow the instructions within the Getting Started After Deployment section to access the application and start using it.
- Supported distributions: Ubuntu 20.04 LTS
- Recommended minimum plan: All plan types and sizes can be used.
- Rails Application name (required): The name for your rails application.
After Ruby on Rails has finished installing, you will be able to access Ruby on Rails from the console via ssh with your Linode’s IPv4 address:
Log out and log back in as your limited user account.
Update your server:
sudo apt-get update && apt-get upgrade
Ruby comes with some pre-made scripts to get you started. One of these is a blog. To begin with the blog example, use the following command:
rails new blog
This creates a new Rails application called Blog in the

Start the built in server with the following command, replacing the IP address with your Linode’s IP address:
rails server --binding=198.51.100.0

You can visit your application by visiting the address in the browser.
Exit the server process with Ctrl+C.
A controller will receive requests which are then routed and served by various actions. A view displays information.
Create a controller called
Welcomeand an action called
rails generate controller Welcome index
With the text editor of your choice, edit the file
app/views/welcome/index.html.erband replace the contents with the following:
- File: app/views/welcome/index.html.erb
<h1>Hello, World! This is Ruby on Rails!</h1>
Tell Rails where to find the document root. Edit the file
config/routes.rb, find and uncomment the line root as shown:
- File: config/routes
1 2 3 4 5 6 7 8 9
Rails.application.routes.draw do get 'welcome/index' ... root 'welcome#index' ... end
Start the server again:
rails server --binding=198.51.100.0
You should see your new welcome page in the web browser.
