INSTALLING OPENSTACK(using devstack)

WHAT IS OPENSTACK

• OpenStack is a free, open standard cloud computing platform. It is mostly deployed as infrastructure-as-a-service in both public and private clouds where virtual servers and other resources are made available to users

Step 1: Update and Upgrade the System

apt update -y && apt upgrade -y

Step 2: Create Stack user and assign sudo priviledge

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

sudo chmod +x /opt/stack

Next, run the command below to assign sudo privileges to the user

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

Step 3: Install git and download DevStack

su - stack

Once you have successfully created the user ‘stack’ and assigned sudo privileges, switch to the user using the command.

sudo apt install git -y

Using git, clone devstack’s git repository as shown.

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

Step 4: Create devstack configuration file

In this step, navigate to the devstack directory.

cd devstack

Then create a local.conf configuration file.

vim local.conf

Paste the following content

[[local|localrc]]
# Password for KeyStone, Database, RabbitMQ and Service
ADMIN_PASSWORD=StrongAdminSecret
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
# Host IP - get your Server/VM IP address from ip addr command
HOST_IP=10.208.0.10

Save and exit the text editor. NOTE:

The ADMIN_PASSWORD is the password that you will use to log in to the OpenStack login page. The default username is admin. The HOST_IP is your system’s IP address that is obtained by running ifconfig or ip addr commands.
