OpenStack - Lab 1: Installing OpenStack (Single node) using Packstack
Installing OpenStack (Single node) using Packstack
In Lab 1: Installing OpenStack (Single Node) using Packstack, participants typically focus on the deployment and configuration of a basic OpenStack environment on a single node using the Packstack tool. Packstack is a utility that simplifies the installation process by automating the deployment of various OpenStack services. This lab involves setting up prerequisites, running the Packstack installer, and configuring essential parameters such as authentication credentials and networking options. Participants may also explore the OpenStack dashboard (Horizon) to verify the successful deployment of services like Nova, Glance, and Neutron. The lab aims to provide hands-on experience in quickly establishing a functional OpenStack environment on a single node, allowing participants to gain familiarity with the initial setup and configuration processes. Successful completion of Lab 1 equips participants with the foundational skills to deploy OpenStack using Packstack for testing and development purposes.
Lab:
Installing Openstack on CentOS with Packstack
Setup Linux environment
\# Create a user called 'stackuser' and allow super user privileges to it.
useradd stackuser
visudo
stackuser ALL=(ALL) NOPASSWD: ALL
# Login with 'stackuser' and manage services.
su - stackuser
sudo systemctl disable --now firewalld
sudo systemctl disable --now NetworkManager
sudo systemctl enable --now network
Setup static IP
\# Know your network card name.
