This file installs Jekyll on a ubuntu trusty box. After that a test site is generated at the Vagrantfile directory and the jekyll server is startet at this directory.
This jekyll installation is using Ruby 2.2.1. and RMV to install it.
The standard configuration forwards port 4000. Therefore http://localhost:4000 starts the test site. Vagrant starts Jekyll as a backround service.
To start jekyll manually start within the directory you edit your jekyll site:
jekyll serve -P 4000 -H 0.0.0.0
To change to the forwarded port one has to edit Vagrantfile.
