In this article I’ll try to explain how to run Ruby on Rails applications on a server managed by Plesk. Plesk itself does not support modern Rails apps natively. But this doesn’t mean that you cannot deploy Ruby On Rails apps to Plesk hosting.
We will use an Ubuntu 14.04 server and Plesk 12.0 for our experiments. I assume that you will get this configuration somehow. It’s possible to deploy Rails apps on different OS and using different Plesk version, but all further commands will rely on Ubuntu 14.04 and Plesk 12.0 capabilities.
