Foreword
This book is for systems administrators who are either interested in, looking to switch to, or have chosen Oracle Linux for their IT infrastructure. Welcome!
Oracle Linux Cookbook brings together two great technologists (Erik Benner and Erik Thomsen) serving up a generous helping of Linux know-how that will have you hungry for more. The Eriks share their combined knowledge and experience through easy-to-follow steps, troubleshooting tips, and tested best practices that can help you master adopting and managing your Oracle Linux systems.
I’ve had the pleasure of knowing Erik Benner for many years, as we’ve both worked with (or in my case, at) Oracle since the mid-late 1990s. Erik is well versed in core Oracle technologies, including Oracle Linux, Oracle Cloud, and Oracle Database. His experience in creating, delivering, and managing Oracle-based solutions spans government and commercial customers of all sizes, which means he’s dealt with nearly everything imaginable when it comes to technology implementations—from those that deserved a Michelin star rating to those he’s had to save from being undercooked catastrophes.
A member of the Oracle Linux team, Erik B. Thomsen started his software career while on active duty in the US Air Force. There, he sought creative, out-of-the-box ways to solve problems, including using database technology. He sharpened his skills at a global aerospace company where his passion for Linux and open source software took hold. He has held positions including as a DBA, product manager, and DevOps engineer. Erik is passionate about delivering finely assembled technological solutions and writing thorough procedural documentation, akin to a masterful recipe. He has proved his mettle helping customers streamline processes and achieve outstanding results.
Jonathan Spindel is a seasoned technologist and an Oracle subject matter expert, with more than 23 years of experience providing end-to-end management and delivering turnkey cloud solutions. This, coupled with his expertise in automation leads to high quality processes and satisfied customers.
Oracle Linux Cookbook covers a wide range of topics: from installation and upgrades to software management and security to storage and containers. Several Oracle Linux ingredients are detailed, such as the Unbreakable Enterprise Kernel, Red Hat Compatible Kernel, Btrfs, Leapp, and Podman. A chapter is dedicated to the use of Oracle Ksplice to help you improve system security. Guides to building an operational Preboot Execution Environment (PXE) are provided and Application Streams are described in depth. You will also discover how to automate tasks with Ansible and Terraform and build RPM packages for custom applications.
After reading this book, you’ll have a solid understanding of Oracle Linux and how to use it to optimize server performance, availability, and security—in addition to getting a taste of what makes it unique among Enterprise Linux distributions. In my decades of working with our customers, they consistently say that performance, stability, and security are the key reasons they’ve become Oracle Linux connoisseurs. I hope you’ll join them.
Whether you’re new to Oracle Linux or an experienced systems administrator continuing to sharpen your skills, this is an excellent reference book and one that should become an indispensable addition to your bookshelf.
It’s time to get cooking with Oracle Linux.
