Overview of this book

Discover the power of Oracle Linux 8, the free and enterprise-grade Linux distribution designed for use in any environment, with this recipe-style book. Starting with instructions on how to obtain Oracle Linux for both X86 and ARM-based platforms, this book walks you through various installation methods, from running it as a Windows service to installing it on a Raspberry Pi. It unravels advanced topics such as system upgrades using Leapp for major version transitions and using a PXE server and kickstart files for more advanced installations. The book then delves into swapping kernels to take advantage of Oracle’s UEK, exploring boot options, managing software with DNF, and achieving high availability. Detailed recipes involving security topics will assist with tasks such as data encryption, both at rest and in motion. For developers, it offers guidance on building RPM files, using Docker and Podman in a containerized environment, working with AppStreams, and more. For large-scale deployments, the book introduces Oracle Linux Automation Manager for enterprise-level Ansible utilization, from setting up the Ansible server to basic playbook writing. Finally, you’ll discover strategies for cloud migration. By the end of this book, you’ll possess a comprehensive toolkit that will elevate your skills as a Linux administrator.

Technical requirements

For most of these recipes, you will need a pair of Oracle Linux 8 systems. As with most of these recipes, a VM on your desktop using a desktop virtualization product such as Oracle VirtualBox is recommended. A small VM is fine, with two cores, 2 GB RAM, and a few free gigabytes of disk space. You will also need some additional disks assigned to the VM, ideally at least five equally sized disks. Before you start, patch your system to the latest packages available. This only takes a few minutes and can save a ton of time when troubleshooting issues that are caused by a bug.
