Enterprise level web and mapping applications, we are your able technology partners.

I recently created a couple of Centos virtual machines, and took notes of all the steps. You can use these notes for both installing another VM, or for building a production server.

We used these VMs for running staging and production instances of a Ruby on Rails deployment.
