How to Install OpenStack in Ubuntu 20.04

OpenStack is an open-source cloud computing platform that allows you to create and manage a private or public cloud environment. It provides tools and services for building and managing cloud infrastructure. In this guide, we will walk you through the step-by-step process to install OpenStack in Ubuntu 20.04, one of the most popular Linux distributions.

Prerequisites

– A Linux VPS with Ubuntu 20.04 Operating System

– Minimum of 8 GB RAM

– 64-bit processor

– At least 128 GB of disk space

Step.1: Update your Ubuntu Server

Make sure your server is updated using the following commands:

sudo apt update

sudo apt upgrade -y

Step.2:Create Stack User

To install OpenStack on a non-root user with sudo enabled, generating a fresh user called “stack” is imperative. For this, follow the steps below.

First, run the following command:

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

Now you need to enable the stack user to have root privileges using the following command:

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

It is time to Log in to the stack user using the following command:

sudo su - stack

Step.3: Install OpenStack packages

OpenStack can be installed using the “devstack” project, which provides a script to simplify the installation process. Begin by cloning the “devstack” repository:

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

Step.4: Configuration

Once the repository is cloned, navigate to the “devstack” directory and create a “local.conf” file to customize your OpenStack installation:

cd devstack

Now, open the “local.conf” file using a text editor:

nano local.conf

and make the following modifications:

ADMIN_PASSWORD=StrongAdminSecret
DATABASE_PASSWORD=$ADMIN_PASSWOCinder
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD

Set the IP address of your server for the “HOST_IP” variable:

HOST_IP=YourServerIP

Enable the required OpenStack services by uncommenting the respective lines:

ENABLED_SERVICES=n-cpu,n-net,rabbit,g-api,g-reg,key,n-api-meta,neutron-api,neutron-dhcp-agent,neutron-l3-agent,neutron-metadata-agent

Save and close the file.

Step.5: Starting the installation

You are now ready to start the OpenStack installation. Run the following command:

./stack.sh

This command will begin the installation process and may take some time to complete. Make sure to grab a cup of coffee while it runs.

Step.6: Accessing the OpenStack Dashboard

Once the installation is complete, you can access the OpenStack Dashboard, also known as Horizon, through a web browser. Open your browser and enter the following URL:

http://YourServerIP/dashboard

Log in with the username “admin” and the password you set during the configuration step.

Congratulations! You have successfully installed OpenStack on Ubuntu 20.04.
