Preparing OpenStack Queens Installation

OpenStack will be deployed with the help of PackStack package provided by rdo repository (RPM Distribution of OpenStack):

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:

vi 03.09.18.conf

CONFIG_NTP_SERVERS=0.ro.pool.ntp.org
CONFIG_PROVISION_DEMO=n
CONFIG_KEYSTONE_ADMIN_PW=your_password          # For Admin user
