Create stand-alone system services in Ruby

Question

I want to build application which servers as a stand-alone system service, always run on the backend and servers a front-end with a web interface.

Like we do in Linux /etc/init.d/apache2 start , Same as I want to server my application /etc/init.d/myapp start .

My major target is to deliver on Linux specially Ubuntu, whole app would be in plain Ruby and front-end would be in Sinatra.

I want to make it install with simple, gem install my_app and command line features get available to start the service. The application would be doing heavily processing and database insertion. And I want that its configurations must be set as in pure linux fashion, like /etc/apache2/apache2.conf

Can any one guide me in it? Also if possible, i want to secure the code, is there any possibilities for it?

Answer 1

I am using the Daemon-Kit gem for the same requirements. Works very well in production. The only thing it does not include is the configuration with a .conf file, but it's easy to do it yourself with Ruby code. You can deploy with Capistrano, no need to install.
