Whether you're a beginner or an experienced developer, this comprehensive guide will provide the necessary knowledge to get started.

Minimum Requirements for Installing OpenStack

To install OpenStack on your local machine, you need to ensure that your system meets the minimum requirements. This guide specifically focuses on the Ubuntu environment, as it is known to work well and easily with OpenStack.

Step-by-Step Guide to Set Up OpenStack on Your Local Machine

Step 1: Update and Upgrade the System

Before starting with the installation, ensure that your system is updated and upgraded. Open a terminal and run the following commands:

sudo apt updatesudo apt upgrade

Step 2: Create Stack User and Assign Sudo Privileges

Next, create a stack user and assign it sudo privileges. This is necessary to run the DevStack installation process seamlessly.

sudo useradd -m -s /bin/bash stacksudo passwd stacksudo usermod -a -G sudo stack

Step 3: Install git and Download DevStack

DevStack is a script that automates the installation and configuration of OpenStack. To install DevStack, first, install git and then download DevStack using the following commands:

sudo apt install gitgit clone 

Step 4: Create DevStack Configuration File

DevStack is highly customizable. You can create a file to configure your installation according to your needs. Below is a sample configuration file:

[[local|localrc]]ADMIN_PASSWORDadminDATABASE_PASSWORDadminRABBIT_PASSWORDadminSERVICE_PASSWORDadminENABLED_SERVICESn-api,n-caas,n-obj,n-cpu,n-sched,n-axnova,n-sec,n-orch,n-cinder,n-db,n-heat,n-ceilometer,n-glance,n-asterix,n-pan

Customize the parameters according to your requirements, such as the ADMIN_PASSWORD, DATABASE_PASSWORD, and others.

Step 5: Install OpenStack with DevStack

Once the configuration file is set up, navigate to the devstack directory and run the following command to install OpenStack:

cd devstack

This process may take some time, depending on the speed of your machine.

Step 6: Accessing OpenStack on a Web Browser

Now that OpenStack is installed, you can access it via a web browser. Use the IP address of your machine (or its localhost if you are running it locally) and the default port number 8000 to access the Horizon dashboard. The default username and password are both admin with the password you specified in the file.

For example, you can access it using:

http://localhost:8000

Once you are logged in, you can start exploring the various OpenStack services available, as detailed in the subsequent section.
