$ sudo ./nova.sh branch
$ sudo ./nova.sh install
$ sudo ./nova.sh run

This starts up everything in a screen session.  When you detach the screen
with Ctrl-A, D all of the openstack components will shut down.

The nova.sh script generally sets up a clean environment every time it is
run.  This makes it mostly useful for demo and test environments.

Hopefully this helps.
