Overview

This interface allows you to create and deploy a Ruby on Rails® application.

Create a Ruby on Rails application in version 66 and later

To create a Ruby application in cPanel & WHM version 66 and later, perform the following steps:

  1. Ask your hosting provider to install Ruby on your system via the following EasyApache 4 RPMs:

    • The ea-apache24-mod_env module.

    • The ea-ruby24-ruby-devel module.

  2. Create a Ruby application on your server. For an example of how to do this, read our How to Create Ruby Web Applications documentation.

  3. Use cPanel’s Application Manager interface (cPanel >> Home >> Software >> Application Manager) to register the application.

Create a Ruby on Rails application in version 64 and earlier

After you confirm that your server uses a functional and accessible version of Ruby, you can create and deploy a Ruby on Rails environment.

Because Ruby on Rails runs on its own server, it requires the following steps to set up the environment:

  1. Enter your application’s name in the App Name text box.

  2. To load when the server boots, select the Load on Boot? checkbox.

  3. Enter the application path in the Application Path text box.

     4. In the Environment menu, select the type of Ruby on Rails environment that you prefer.

     5. Click Create.

You can perform the following actions on applications in the Ruby on Rails Applications table:

  • To redirect to an application’s Rails server, click URL.

  • To run an application, click Run.

  • To stop an application, click Stop.

  • To load an application when the server boots, select the Load on Boot? checkbox.

  • To toggle an application between a production or development environment, select or deselect the Production checkbox.

  • To delete an application, click Delete.

Create a Rewrite

Because Ruby on Rails uses its own server and does not respond on the standard HTTP port number 80, you must specify the port where site visitors can access your Ruby on Rails application (for example, example.com:12001).

To configure Ruby to respond without the need for visitors to specify a port number, create a rewrite.

To configure a rewrite, perform the following steps:

  1. In the Create A Rewrite table, click Create Rewrite for the appropriate application

  2. From the menu, select the domain, subdomain, or addon domain on which you wish to run your Ruby application.

    • To run the application from a new page within your domain, enter the page name that you wish to use in the available text box.
  3. Click Save.

You can perform the following actions in the Current Rewrites table:

  • To change an application path name, enter the path name in the text box.

  • To save an application rewrite, click Save.

  • To delete an application rewrite, click Delete.

Additional applications and rewrites

To run multiple Ruby applications, you must configure additional ports to respond with Ruby on Rails and, if necessary, additional rewrites to disguise the port change.

  • To add additional Rails applications, follow the steps in the Create a Ruby on Rails application section.

  • The new application will respond on the next available port number (for example, if your first application runs on port 12001, the second may run on port 12002 or higher).

  • To configure an additional rewrite, follow the steps in the Create a Rewrite section.

  • You will need to use a new domain, addon domain, subdomain, or page (for example, example.com/RubyApplication) for the rewrite.

Note for resellers and web hosts

You can limit the number of Rails applications that your customers can install in WHM’s Modify an Account interface (WHM >> Home >> Account Functions >> Modify An Account). Perform the following steps to set the maximum number of Rails applications:

  1. Click the domain name that you wish to limit.

  2. In the Max Mongrel instances (Ruby on Rails) text box, enter the maximum number of Rails applications that you wish to allow your customers to install.

  3. Click Save.
