A. Initial System Configurations
Update the CentOS 7
Step1:- sudo yum update
list all running services
Step2:- ss -tulpn
Now identify, stop, disable and remove unneeded services, mainly postfix, NetworkManager and firewalld. At the end the only daemon that would be running on your machine should be sshd.
Step3:- systemctl stop postfix firewalld NetworkManager
Step4:- systemctl disable postfix firewalld NetworkManager
Step5:- systemctl mask NetworkManager
Step6:- yum remove postfix NetworkManager NetworkManager-libnm
Completely disable Selinux policy on the machine by issuing the below commands
Step7:- setenforce 0
Step8:- getenforce
Also edit /etc/selinux/config file set SELINUX line from enforcing to disabled
Step9:- vi /etc/selinux/config
SELINUX=disabled
set your Linux system hostname, Replace the FQDN variable
Step10:- hostnamectl set-hostname cloud.centos.lan
install ntpdate command to synchronize time with a NTP server
Step11:- yum install ntpdate
B. Install OpenStack in CentOS and RHEL
In order to enable rdo repositories on RHEL/CentOS 7
Step12:- yum install https://www.rdoproject.org/repos/rdo-release.rpm
Now it’s time to install PackStack package
Step13:- yum install openstack-packstack
The file will be named after the current day timestamp when generated (day, month and year).
Step14:- packstack --gen-answer-file='date +"%d.%m.%y"'.conf
Step15:- ls
Now edit the generated answer configuration file with a text editor
Step16:- vi 22.04.16.conf
In order to be safe replace the passwords fields
Step17:- CONFIG_NTP_SERVERS=0.ro.pool.ntp.org
Please consult http://www.pool.ntp.org/en/ server list in order to use a public NTP server near your physical location

Step23:- vi /etc/ssh/sshd_config
PermitRootLogin Yes
restart SSH service to reflect changes
Step24:- systemctl restart sshd
C. Start Openstack Installation Using Packstack Answer File
start Openstack installation process via the answer file edited
Step25:- packstack --answer-file 13.04.16.conf
If for some reasons the installation process ends with an error regarding httpd service, open /etc/httpd/conf.d/ssl.conf file and make sure you comment the following line as illustrated below
Step26:- #Listen 443 https
restart Apache daemon to apply changes
Step27:- systemctl restart httpd.service
Note: In case you still can’t browse Openstack web panel on port 443 restart the installation process from beginning with the same command issued for the initial deployment.
Step28:- packstack --answer-file /root/22.04.16.conf
E. Remotely Access OpenStack Dashboard
Step29:- https://192.168.1.197/dashboard
username :- admin
