Very basic Redmine Installer
Utilizes vagrant although I'm still learning how to use it.
Just vagrant up a Ubuntu Precise box(although it may not matter really what version of ubuntu) Modify the redmine_installer.sh and change all the user/pass and stuff in there(should be able to just sed or use vim/emacs to do it) Then bash /vagrant/redmine_installer.sh
Should get you setup. Does not setup https yet and by default sets up sendgrid which you may not want so you will have to remove it from config/environments/production.rb if you don't want it
