systemctl stop postfix firewalld NetworkManager
systemctl disable postfix firewalld NetworkManager
systemctl mask NetworkManager
yum remove postfix NetworkManager NetworkManager-libnm

Completely disable Selinux policy

setenforce 0
getenforce
vi /etc/selinux/config

Preparing OpenStack Queens Installation

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

yum install https://www.rdoproject.org/repos/rdo-release.rpm

On CentOS 7, the Extras repository includes the RPM that actives the OpenStack repository.
Extras is already enabled, so you can easily install the RPM to setup the OpenStack repository:

yum install -y centos-release-openstack-queens
yum update -y

Packstack represents a utility which facilitates the deployment on multiple nodes for different components of OpenStack via SSH connections and Puppet modulesL

yum install  openstack-packstack

Generate an answer file for Packstack with the default configurations which will be later edited with the required parameters in order to deploy a standalone installation of Openstack (single node):

packstack --gen-answer-file='date +"%d.%m.%y"'.conf
ls

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
CONFIG_HORIZON_SSL=y                            # Access OpenStack dashboard via HTTP with SSL enabled
CONFIG_MARIADB_PW=mypassword1234                # The root password for MySQL server
CONFIG_NAGIOS_INSTALL=n                         # Disable Nagios

Enable Root SSH login by uncomment below line:

vi /etc/ssh/sshd_config
PermitRootLogin yes

systemctl restart sshd

Start Installation using Packstack Answer File

packstack --answer-file 13.04.16.conf
