How to install OpenStack on your local machine using Devstack

On November 7, we did a mini-course on Top Sysadmin Tasks and How to Do Them with OpenStack, and we promised to give you instructions on how to install OpenStack on your own laptop. Here it is.

The purpose of this guide is to allow you to install and deploy OpenStack on your own laptops or cloud VMs and follow the webinar exercises at home. The guide is both hardware and OS agnostic and can be used with AMD or Intel and Windows, Mac, or Linux. Furthermore the installation below is completely isolated and self contained using Virtual Machines. The guide is provided as is and Mirantis inc. is not responsible for any issues that may occur as a result of following this guide.

Step 1.

Create a Linux VM locally on your computer (for example, using VirtualBox) or remotely in the cloud (for example on AWS).

The VM needs to satisfy the following conditions:

  • VM needs at least 4 GB of memory and access to the Internet, and it needs to be accessible (at least) on tcp ports 22 (or console) and 80 from your laptop.
  • Devstack attempts to support Ubuntu 16.04/17.04, Fedora 24/25, CentOS/RHEL 7, as well as Debian and OpenSUSE.
  • If you do not have a preference, Ubuntu 16.04 is the most tested, and will probably go the smoothest.

Warning:

DevStack will make substantial changes to your system during installation. Only run DevStack on servers or virtual machines that are dedicated to this purpose.

Step 2.

Log into the VM using ssh or the console.

Step 3.

You’ll need to run Devstack as a non-root user with sudo enabled.  You can quickly create a separate user called stack to run DevStack with:

sudo useradd -s /bin/bash -d /opt/stack -m stack

Step 4.

Because this user, stack, will be making many changes to your system, it should have sudo privileges:

echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack

You should see output of:

stack ALL=(ALL) NOPASSWD: ALL

Step 5.

Now you need to switch over to use the user stack:

sudo su - stack

Step 6.

Download DevStack:

git clone https://github.com/openstack-dev/devstack.git -b stable/pike devstack/

You should see:

Cloning into 'devstack'...

Notes

The above command downloads OpenStack release Pike.  You can also check the list of available releases.  To download releases in EOL status (End Of Life) replace -b stable/pike

with, for example, -b liberty-eol (for Liberty).

Step 7.

Change to the devstack directory:

cd devstack/

Step 8:

Determine your IP address:

sudo ifconfig

You will see a response something like this:

enp0s3 Link encap:Ethernet  HWaddr 08:00:27:ea:97:9f  
       inet addr:10.0.2.15  Bcast:10.0.2.255  Mask:255.255.255.0
       inet6 addr: fe80::d715:6025:f469:6f7c/64 Scope:Link
       UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
       RX packets:1364291 errors:0 dropped:0 overruns:0 frame:0
       TX packets:406550 errors:0 dropped:0 overruns:0 carrier:0
       collisions:0 txqueuelen:1000
       RX bytes:1415725472 (1.4 GB)  TX bytes:27942474 (27.9 MB)

lo     Link encap:Local Loopback  
       inet addr:127.0.0.1  Mask:255.0.0.0
       inet6 addr: ::1/128 Scope:Host
       UP LOOPBACK RUNNING  MTU:65536  Metric:1
       RX packets:229208 errors:0 dropped:0 overruns:0 frame:0
       TX packets:229208 errors:0 dropped:0 overruns:0 carrier:0
       collisions:0 txqueuelen:1000
       RX bytes:89805124 (89.8 MB)  TX bytes:89805124 (89.8 MB)

You’re looking for the addr: value in an interface other than lo.  For example, in this case, it’s 10.0.2.15.  Make note of that for the next step. If you run your VM on the cloud, make sure to use the public IP of your VM in the link.

Step 9.

Create the local.conf file with 4 passwords and your host IP, which you determined in the last step:

cat >  local.conf <<EOF
[[local|localrc]]
ADMIN_PASSWORD=secret
DATABASE_PASSWORD=\$ADMIN_PASSWORD
RABBIT_PASSWORD=\$ADMIN_PASSWORD
SERVICE_PASSWORD=\$ADMIN_PASSWORD
HOST_IP=10.0.2.15
RECLONE=yes
EOF

This is the minimum required config to get started with DevStack.

Step 10.

Now install and run OpenStack:

./stack.sh

At the end of the process you should see output something like this:

This is your host IP address: 10.0.2.15
This is your host IPv6 address: ::1
Horizon is now available at http://10.0.2.15/dashboard
Keystone is serving at http://10.0.2.15/identity/
The default users are: admin and demo
The password: secret
DevStack Version: pike
OS Version: Ubuntu 16.04 xenial
stack.sh completed in 1221 seconds.

This will take a 15 – 20 minutes, largely depending on the speed of your internet connection. Many git trees and packages will be installed during this process.

Step 11.

Access your OpenStack by copy-pasting the link from the above output into your web browser:

http://<HOST_IP>/dashboard

Use the default users demo or admin and configured password from step 8 (secret).

You should see the following log-in window in your browser:

openstack_devstack_login

From here, you can do whatever you need to, either from the Horizon interface, or by downloading credentials to use the command line.

You can find out how to do some of the more common tasks by viewing the original webinar, or check out our OpenStack Training resources.

  9. Try upgrading pip and setuptools. It helped for me.

    #pip install –upgrade pip

  10. Hello to you and thank you very much for your installation guide that I followed to the letter. However, I am struck by an error during the finalization of my installation.
    My error code is as follows:
    devstack @ Job for DCE. Service flawed because the control process exided with error code.
    See “Systemct1 Status Devstack @ DCE. service ” and “Journalct1-XE ” for details.
    Please help me find a solution for my problem. Thank you well, I stay tuned

  13. The problem seems to affect computers with PPC arch.
    There is no etcd 3.1.7 for PPC.

    You can try several solutions:

    1)
    switch to some newer releases of OpenStack

    or

    2)
    change etcd version to some newer version with PPC arch supported
    somewere in local.conf:
    ETCD_DOWNLOAD_URL=some_url
    to
    https://github.com/etcd-io/etcd/releases/download/v3.2.0-rc.1/etcd-v3.2.0-rc.1-linux-ppc64le.tar.gz
    (from https://github.com/etcd-io/etcd/releases/tag/v3.2.0-rc.1)

    or

    3)
    disable etcd in local.conf:
    disable_service etcd3

    but it might break other things 🙁

  14. Kindly include chown -R stack /opt/stack/.cache into installation list. As it’s giving permission error while installation

  17. What ubuntu version are you using?
    Devstack is not tested in Ubuntu 18.04 so, if you try to install it in this version, you will get this error.

  19. When I try this command “sudo ifconfig”, it asks me for “stack” user password, but I didn’t setup a password in the previous step?
