Unleashing the Power of OpenStack on CentOS 9 Stream: A Step-by-Step Guide

Are you ready to take your cloud computing experience to the next level? Look no further! In this comprehensive guide, we’ll show you how to install and configure OpenStack on CentOS 9 Stream, the latest and greatest iteration of the popular Linux distribution. Buckle up, folks, as we dive into the world of open-source cloud computing.

What is OpenStack?

Before we get started, let’s quickly cover the basics. OpenStack is an open-source cloud computing platform that allows you to create and manage virtual machines, storage, and networking resources. It’s a powerful tool that enables you to build and deploy complex cloud infrastructure, all while maintaining complete control and flexibility.

Why Choose CentOS 9 Stream?

CentOS 9 Stream is the latest version of the CentOS Linux distribution, and it’s the perfect choice for running OpenStack. With its cutting-edge features and improved performance, CentOS 9 Stream provides a rock-solid foundation for your OpenStack deployment. Plus, it’s fully compatible with OpenStack, making it an ideal combination for building a robust cloud infrastructure.

Prerequisites

Before we begin, make sure you have the following prerequisites in place:

• A fresh installation of CentOS 9 Stream (Minimal Install)

Step 1: Install OpenStack Packages

Let’s get started by installing the necessary OpenStack packages. Run the following command to enable the OpenStack repository:

sudo dnf config-manager --set-enabled openstack-stein

Next, install the OpenStack packages using the following command:

sudo dnf install -y openstack-stein-all

This will take some time, so be patient and grab a cup of your favorite brew.

Step 2: Configure Network Settings

OpenStack requires specific network settings to function properly. Let’s configure our network settings to work with OpenStack:

Edit the /etc/sysconfig/network-scripts/ifcfg-ens160 file using your favorite text editor (e.g., vi, nano):

sudo vi /etc/sysconfig/network-scripts/ifcfg-ens160

Add the following lines to the end of the file:

ONBOOT=yes
IPV6INIT=yes
IPV6_AUTOCONF=yes

Save and exit the file.

Restart the network service to apply the changes:

sudo systemctl restart network

Step 3: Configure OpenStack Services

Now that we have the OpenStack packages installed, let’s configure the services:

Edit the /etc/openstack/tagger.conf file using your favorite text editor:

sudo vi /etc/openstack/tagger.conf

Update the following lines:

[DEFAULT]
# ...
debug = True

Save and exit the file.

Edit the /etc/openstack/nova.conf file using your favorite text editor:

sudo vi /etc/openstack/nova.conf

Update the following lines:

[DEFAULT]
# ...
compute_driver=libvirt.LibvirtDriver

Save and exit the file.

Step 4: Initialize OpenStack Services

Now that we have the configuration files updated, let’s initialize the OpenStack services:

sudo openstack-db --service glance --init
sudo openstack-db --service nova --init
sudo openstack-db --service neutron --init

This will initialize the Glance, Nova, and Neutron databases.

Step 5: Start OpenStack Services

Finally, let’s start the OpenStack services:

sudo systemctl start openstack-glance-api
sudo systemctl start openstack-nova-api
sudo systemctl start openstack-neutron-server

This will start the Glance, Nova, and Neutron services.

Step 6: Verify OpenStack Installation

Let’s verify that OpenStack is installed and running correctly:

sudo openstack token issue

This should display an authentication token. If you see an error, check your logs for any issues.

Conclusion

Congratulations! You have successfully installed and configured OpenStack on CentOS 9 Stream. You now have a fully functional open-source cloud computing platform at your disposal.

From here, you can explore the various OpenStack services, such as Nova, Glance, and Neutron, and start building your cloud infrastructure. Remember to keep your OpenStack installation up-to-date with the latest security patches and updates.
