Creating your private cloud using OpenStack – (2) – Preparing the nodes

This blog lists the steps to prepare two nodes, the controller and one compute node, for setting up your own private cloud using OpenStack. The process entails configuring network interfaces, enabling repositories and services on both the nodes and installing a SQL database engine, PostgreSQL in this case. The blog also explains how to change authentication methods of PostgreSQL and allow connections from the same subnet. Once the nodes are prepared, the process proceeds with the deployment of the first OpenStack service: the identity service (Keystone).
Preparing the nodes involves installing a minimal installation of Rocky Linux 9 on both machines. Configuring network interfaces requires setting up a static configuration for both network interfaces on each of the nodes. For time synchronization, the controller node synchronizes time from the internet, while the compute node synchronizes its time from the controller node.
The process of preparing the nodes requires allowing other nodes in the same subnet to synchronize from the controller node. It further requires installing a SQL database engine on the controller node which could handle the configurations of several OpenStack services. In this case, a single instance of PostgreSQL is installed on the controller node.
Additionally, configuring authentication to 'scram-sha-256' and allowing external connections on PostgreSQL, enabling Red Hat's repositories, and installing OpenStack client follows ensuring name resolution through a host file.
Once the nodes are prepared, the next step of deployment includes configuring the first OpenStack service, which is the identity service, using Keystone. This blog is part of a series of articles discussing the creation of a private cloud using OpenStack.

Two technology trade groups, NetChoice and TechNet, have filed a lawsuit against the U.S. CFPB to block a new rule granting supervisory power over payment apps and digital wallets.
The groups argue that the CFPB lacks the authority to regulate non-bank entities offering consumer financial services through products like Apple Wallet, Google Pay, and Venmo.
The CFPB failed to demonstrate any consumer risks or gaps in regulatory oversight justifying the rule, according to the complaint filed in federal court.
The trade groups believe the rule is an unlawful power grab that could hinder innovation, reduce competition, and increase prices.
