The installation of Ontohub is described at the github page.
An automated script for installation under Ubuntu 12.04 can be found here. Run the script with
bash install-on-ubuntu develop
for e.g. installing the develop branch.
A virtual machine image (based on a Ubuntu 12.04.3 server guest, for use with VirtualBoc or VMWare) can be found here. Username and password are ontohub. Start a rails server with
cd Workspace/Ontohub rails s
Then you can see your Ontohub instance at http://localhost:3000. If you use the VirtualBox config file, some port redirections will ensure that your port 3000 will be redirected to the VM, and you can ssh to the VM with "ssh -p 2222 ontohub@localhost". If you want to set up a productive environment, see the github page for Apache etc.
