Openstack Deployment to one Server

After struggling to deploy my first openstack installation, I thought I had to share to save time for someone else – here is a simple guide to deploy an openstack installation on one server machine.

Hardware Requirements

1. VM or Bare metal Server
2. At least 16GB RAM
3. At least 100GB Hard disk
4. At least 2 Core of Processor
5. Linux – Centos 7 preferred

Time

40 Minutes

Get started to your first Openstack Installation

Deploying Openstack – all in one using packstack

$ sudo yum install -y centos-release-openstack-queens

$ sudo yum update -y

$ sudo yum install -y openstack-packstack

$ sudo packstack –allinone

You will likely encounter the error

import pkg_resources

ImportError: No module named pkg_resources

ERROR : No module named pkg_resources

Just run this command

wget https://bootstrap.pypa.io/ez_setup.py -O – | python

This will install the missing python packages

Prepare the environment further more by running the following commands

Networking

$ sudo systemctl disable firewalld

$ sudo systemctl stop firewalld

$ sudo systemctl disable NetworkManager

$ sudo systemctl stop NetworkManager

$ sudo systemctl enable network

$ sudo systemctl start network

Install Openstack Queens

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

Enable the repository

yum-config-manager –enable openstack-queens

Update the repository

$ sudo yum update -y

Install the packstack installer

$ sudo yum install -y openstack-packstack

Finally run the packstack to install the openstack

$ sudo packstack –allinone

Access

Credentials

Obtain the credentials on file

Open the file /root/ keystonerc_admin

export OS_USERNAME=admin

export OS_PASSWORD=’510102e11a734891′

or

/root/ keystonerc_demo

export OS_USERNAME=demo

export OS_PASSWORD=’8db7145e0df64bd2′

As soon as I hack it on multiple machines in different regions – I will share that simple guide on how to deploy Openstack on Multiple machines (centos 7 / Redhat)

Am also working to deploy Openstack on Ubuntu 16 over MaaS and Juju – Check out for this simple guide later as well.
