OpenStack-Setup-and-Testing

In this project ill be completing 3 tasks:

• Deploying a Basic OpenStack Setup (All-in-One Node)✅
• Setting up a Multi-node OpenStack Deployment (ENV)
• Deploying a highly available Openstack ENV and using Automation with Heat Orchestartion

Loading

== STEP BY STEP COMPLETION OF Deploying a Basic OpenStack Setup (All-in-One Node) ==

[] PREQ:

• CentOS Stream 9 OS
• At least 4 GB RAM, 20 GB Disk Space, 2 CPU cores

Preperation and Setup ===

Step 1: . Update system packages::

sudo yum update -y

Step 2: . Temporarily Disable SELinux and Firewalld (NOTE: DO NOT DO THIS IN PRODUCTION!!)

Step 3: . When configuring the network settings, make sure the IP is static

Installing Packstack and OpenStack ===

Step 1: . Install the OpenStack Repo zed::

Step 2: . Install Packstack::

Step 3: . Now run the Pack installer. This will iniate an automated deployment of all core OpenStack Components. (Command is below):

sudo packstack --allinone

This will take 15-30minutes to complete..

Still going, Ill waiting for it to finish building::

Build completed with some errors, but lets test to see if the UI is still accessible with out any issues:

CHECKING..:

UI Looks to be Inaccessible::

I'll TroubleShoot the Issue.

RESULT::

UI is now accessible..

Lets quickly walk through what I did in the Backend to fix this:

• I stopped and disabled the NetworkManger service
• I ran the less /var/tmp/packstack/20241002-194116-lj_a_ufq/manifests/10.0.0.151_controller.pp.log command to get more context and information on what exactly was causing the issue
• 2 things...that I read from the errors that could be potential fixes: First, Openstack-glance was failing to install. Second, python3-pyxattr was struggling to be installed during the automation sequence
• Action to fix: First, I ran the command dnf config-manager --set-enabled crb to enable the crb repo. Next, I ran the command dnf clean all && dnf makecache to rebuild DNF Cache and update repos. Next, I did a manual installation of pyxattr by using the command dnf install -y python3-pyxattr. And then I ran the command dnf install -y openstack-glance to install the openstack-glance package now that pyxattr was available and successfully installed. Finally I reiniated the build by running the packstack --answer-file /root/packstack-answers-20241002-194118.txt command...and tested for success after the build was finished

Now there's Issues Authenticating:

Could Stem from this error:

Will TroubleShoot

SUCCESS!:

Lets quickly walk through how I Fixed this:

• I stopped the Apache service with the systemctl stop httpd command
• I resetted the passwd with the command: keystone-manage bootstrap --bootstrap-password 'ENTER_NEW_PASSWD_HERE' \ --bootstrap-admin-url http://10.0.0.151:5000/v3/ \ --bootstrap-internal-url http://10.0.0.151:5000/v3/ \ --bootstrap-public-url http://10.0.0.151:5000/v3/ \ --bootstrap-region-id RegionOne
• I updated the ~/keystonerc_admin dir with the new passwd then sourced the dir
• I then started the apache service with systemctl start httpd
• Then I retested the login with the new passwd

I expect to encounter More issues as I go along but thats part of the work so I expect it and have full confidence ill always figure it out

======== NOW ON TO THE NEXT TASK IN THIS PROJECT =========

== STEP BY STEP COMPLETION OF Setting up a Multi-node OpenStack Deployment (ENV) ==

Since I already have the controller node built ill go ahead and configure the other two nodes within the packstack answers.txt file

now ill run the packstack --answer-file=packstack-answers-20241002-194118.txt command to deploy the multi-node env

NOTE: Make sure you have a passwordless SSH connection established to each node before deploying the env

DEPLOYING MULTI-NODE ENV:

WILL TAKE A WHILE (15 - 30 mins)
