DevStack is an opinionated script to quickly create an OpenStack development environment. It can also be used to demonstrate starting/running OpenStack services and provide examples of using them from a command line. This post is going to present the steps how to install DevStack into a VMware workstation Ubuntu VM.
Youtube Video: 1. Prepare Ubuntu VM This Ubuntu Virtual machine will need at least 12G memory and 100G hard drive. I have given my OpenStack VM 16G memory and 120G hard drive for testing. 
2. Update System and change sources.list file You may want to remove or comment cdrom entry from your default installed Ubuntu sources.list. I found if I did not do this, my Ubuntu will get some error message to say:
To resolve this problem from terminal you must remove/comment this CD-ROM repository source directly from
/etc/apt/sources.list
and comment or remove lines that include cdrom. eg:
Now it is time to update / upgrade Ubuntu system:
sudo apt-get update sudo apt-get upgrade 3. Install git and clone Devstack to local sudo apt-get install git cd / sudo git clone https://git.openstack.org/openstack-dev/devstack master 4. Prepare to install Devstack 4.1 copy a sample configuration file to use for installation cd /master sudo cp samples/local.conf local.conf sudo nano local.conf
Search for the password variable section and ensure it reflects the following (YOURPASSWORD is the actual password you want to use):
ADMIN_PASSWORD=YOURPASSWORD MYSQL_PASSWORD=$ADMIN_PASSWORD RABBIT_PASSWORD=$ADMIN_PASSWORD SERVICE_PASSWORD=$ADMIN_PASSWORD 
4.2 Create a new user 'stack' and change master folder permission to this new user We can use a pre-installed script to create a new user for devstack. The command to run this script is: sudo /devstack/tools/create-stack-user.shOnce the script completes, you'll need to change the permissions of the master folder with the command: sudo chown -R stack:stack /master5. Start DevStack installation This must be run as the stack user. lets change current user to our new created user - stack. sudo su stackFinal command to start installation: ./stack.shThen it is a long time to wait, more than 45 minutes for me. At the end, once you see following output, your DevStack installation is successful.
