It's been a while since I've updated this site, but it's not because I haven't been working on Rockets! In fact, I've been using and improving it at my job, and I'm doing work for not only the 1.0 release but some design work for what I want to see in Rockets 2.0!
In the mean time, I've made a new script that will do all the installation and configuring for Rockets on a bare-bones Ubuntu 14 LTS server. All you have to do is add the "LAMP" stack (and OpenSSH server) at installation time when you're creating your server, then log in via SSH, type
sudo chmod +x install_rockets.sh
