openstack liberty deployment using devstack in ubuntu-14.04 lts

1. Select a Linux Distribution
   
   
   Only Ubuntu 14.04 (Trusty), Fedora 22 (or Fedora 23) and CentOS/RHEL 7 are documented here. OpenStack also runs and is packaged on other flavors of Linux such as OpenSUSE and Debian.
   
2. Install Selected OS
   
   
   In order to correctly install all the dependencies, we assume a specific minimal version of the supported distributions to make it as easy as possible. We recommend using a minimal install of Ubuntu or Fedora server in a VM if this is your first time.
   
3. Download DevStack
   
   

   git clone https://git.openstack.org/openstack-dev/devstack

   The devstack repo contains a script that installs OpenStack and templates for configuration files
   
4. Configure
   
   
   We recommend at least a Minimal Configuration be set up:
   
5. Add Stack User
   
   
   Devstack should be run as a non-root user with sudo enabled (standard logins to cloud images such as “ubuntu” or “cloud-user” are usually fine).
   You can quickly create a separate stack user to run DevStack with
   

   devstack/tools/create-stack-user.sh; su stack

6. Start the install
   
   

   cd devstack; ./stack.sh
