Install OpenStack - DevStack into Ubuntu 16.04.05 Virtual Machine

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:

The repository 'cdrom://Ubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1) xenial Release' does not have a Release file.
Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
See apt-secure(8) manpage for repository creation and user configuration details.
The repository 'ppa.launchpad.net/kirillshkrogalev/ffmpeg-next/ubuntu xenial Release' does not have a Release file.
Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
See apt-secure(8) manpage for repository creation and user configuration details.
Failed to fetch cdrom://Ubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1)/dists/xenial/main/binary-amd64/Packages  Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs
Some index files failed to download. They have been ignored, or old ones used instead.

To resolve this problem from terminal you must remove/comment this CD-ROM repository source directly from /etc/apt/sources.list
 sudo nano /etc/apt/sources.list
and comment or remove lines that include cdrom. eg:
deb cdrom:[Ubuntu-Server 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.3)]/ xenial main restricted
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.sh
Once the script completes, you'll need to change the permissions of the master folder with the command:
sudo chown -R stack:stack /master
5. Start DevStack installation

This must be run as the stack user. lets change current user to our new created user - stack.
sudo su stack
Final command to start installation:
./stack.sh
Then 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.

6. Launch Browser to log in DevStack



7. Uninstall DevStack.
If there is any change on local.conf file, you will have to uninstall and clean DevStack installation first.
