How to Install OpenStack: A Comprehensive Guide

Prerequisites

Before beginning the installation of OpenStack, ensure you have the following prerequisites in place:

A machine with a fresh installation of Ubuntu Server 20.04 LTS.
An active internet connection.
At least 8GB of RAM and a multi-core processor.
Sudo access on the server.

Step 1: Update Your System

First, update and upgrade your system packages to the latest versions to ensure smooth installation:

sudo apt update && sudo apt upgrade -y

Step 2: Install OpenStack Client

Install the OpenStack client which will be used to manage the OpenStack services:

sudo apt install python3-openstackclient -y

Step 3: Enable OpenStack Repository

Add the OpenStack repository to your system by executing the following commands:

sudo add-apt-repository cloud-archive:victoria

Update your package list after adding the repository:

sudo apt update

Step 4: Install the Database Server

OpenStack requires a database server. Install MariaDB with the following command:

sudo apt install mariadb-server python3-pymysql -y

Secure your database server:

sudo mysql_secure_installation

Step 5: Configure the Database

Edit the MariaDB configuration file at /etc/mysql/mariadb.conf.d/99-openstack.cnf and set the following:


[mysqld]
bind-address = 0.0.0.0
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

Step 6: Install RabbitMQ

RabbitMQ is used as a message broker for communication between OpenStack services. Install it using:

sudo apt install rabbitmq-server -y

Step 7: Install and Configure OpenStack Services

Install identity service, compute service, and other core components necessary for OpenStack. This varies depending on your specific setup. Refer to OpenStack official documentation for specific service installation.

Troubleshooting

If any issues occur during installation, check:

Logs located in /var/log. Specifically, look under service-specific directories like /var/log/nova for compute issues.
Restart the failed service using systemctl restart service-name.
Verify network configurations to ensure OpenStack services can communicate.
