DevStack: Install OpenStack

Persiapan VM

Siapkan VM di VirtualBox

• Memory 4GB
• Akses ke Internet
• Terbuka port 22 dan 80 untuk di akses dari laptop.
• Ubuntu Server kosong dapat digunakan.

WARNING: DevStack akan mengubah sistem habis-habisan saat instalasi. Jalankan DevStack pada server / mesin virtual yang di dedikasikan untuk keperluan tersebut.

Siapkan User

SSH ke VM.

Buat user stack (sudoer) untuk menjalankan DevStack,

sudo useradd -s /bin/bash -d /opt/stack -m stack
echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack

Pindah user

sudo su - stack

Download

Download

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 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.
