Create your own private cloud by using Openstack

OpenStack is an open source platform that uses pooled virtual resources to build and manage private and public clouds.

Create your own private cloud. :)

Here I am using GCP to launch my base machine on top of that we are going to install open stack to launch our own private cloud.You can also used oracle virtual box to use the resources you have in your base machine.

Isn't it cool where you will be having your own private resources and on top of that you are going to deploy various applications .

Here we GO !!!!

I am copying the ISO files which are required for the setup to the remote host machine which I have launched on GCP using WINSCP.

IP of your instance should we Static else if we restart our vm it might get a new public IP again so we must make the public IP static .

The VM configuration that I did for testing purpose:

Prerequisites :

I have copied all ISO files in one folder /software and I have created my own yum repository.

systemctl stop NetworkManager

systemctl disable NetworkManager


systemctl start network

systemctl enable network

systemctl stop firewalld

systemctl disable firewalld

systemctl status firewalld

mkdir /software

Create Yum Repository

yum install -y createrepo

cd /software

Clear the cache

Install openstack-packstack

yum install -y openstack-packstack

rpm -qa | grep puppet

rpm -qa | grep openstack

Generate the file where we are going to define the services we require and clear the cache

packstack --gen-answer-file=a.txt

echo 3 > /proc/sys/vm/drop_caches

Now start installing Redhat Openstack

packstack --answer-file=a.txt

Installation successful !!!!!!!!!!!!!!!!

Now access the Dashboard of the openstack by giving the public IP address on your base machine.Login with the credentials from the file keystonerc_admin

Now start creating your own private instances using your own private resources .

Thats All !! Thanks
