Shared hosting has a lot of upsides for Ruby developers. Since you'll be sharing a physical machine, your expenses will be much less than if you were to rent out a dedicated server. It will also require less maintenance and setup time because the software stack required to host Ruby applications will already be installed by your shared hosting service. They also take the time to maintain — meaning you won't have to deal with security patches and operating system upgrades. With a virtual private server or dedicated hosting, you'll lose a significant amount of time dealing with patches and updates.
Dreamhost is one of the most popular shared hosting services. They offer extraordinary features like unlimited storage and bandwidth, which tends to attract developers.
Dreamhost supports Ruby applications via Apache and Passenger. This includes Ruby on Rails, Sinatra, Ramaze, and any other Rack-based framework. Rack is the interface between Ruby libraries and servers. It's widely used by web frameworks, so you'll have a lot of options if you go with Dreamhost.
Unlimited storage is extremely useful for your website, but also useful if you want to use Dreamhost to hold your private Git repositories. Git comes pre-installed on most of Dreamhost's services, which means you can have an unlimited number of private Git repositories on your account.
Ruby applications run on shared hosting accounts via Rack. Applications can
be configured using the
config.ru file in the application's root directory.
You'll have to consult your framework's documentation on how to configure using
config.ru. As an example, for Sinatra:
require File.expand_path '../myapp.rb', __FILE__ run Sinatra::Application
This will run any Sinatra application in classic mode.
First, go to the control panel. From Domains, go to Manage Domains, then edit. Be sure to enable Ruby on Rails Passenger (aka mod_rails). Add your project directory to the web directory box. Save your changes.
Now from your project directory, create two directories:
config.ru file. Consult your framework's documentation on how to run
the application via Rack.
Although Dreamhost is one of the most popular shared hosting services, there are several more available for hosting Rack based applications. For a full list, see Ruby on Rails Hosts.
