Packstack facilitates the deployment on multiple nodes for different components of OpenStack via SSH connections and Puppet modules:
yum install openstack-packstack
Generate an answer file to deploy a standalone installation of Openstack (single node):
packstack --gen-answer-file='date +"%d.%m.%y"'.conf
Edit the generated answer configuration file with a text editor:
