Book Description
“As an author, editor, and publisher, I never paid much attention to the competition—except in a few cases. This is one of those cases. The UNIX System Administration Handbook is one of the few books we ever measured ourselves against.” —Tim O’Reilly, founder of O’Reilly Media “This edition is for those whose systems live in the cloud or in virtualized data centers; those whose administrative work largely takes the form of automation and configuration source code; those who collaborate closely with developers, network engineers, compliance officers, and all the other worker bees who inhabit the modern hive.” —Paul Vixie, Internet Hall of Fame-recognized innovator and founder of ISC and Farsight Security “This book is fun and functional as a desktop reference. If you use UNIX and Linux systems, you need this book in your short-reach library. It covers a bit of the systems’ history but doesn’t bloviate. It’s just straight-forward information delivered in a colorful and memorable fashion.” —Jason A. Nunnelley UNIX® and Linux® System Administration Handbook, Fifth Edition, is today’s definitive guide to installing, configuring, and maintaining any UNIX or Linux system, including systems that supply core Internet and cloud infrastructure. Updated for new distributions and cloud environments, this comprehensive guide covers best practices for every facet of system administration, including storage management, network design and administration, security, web hosting, automation, configuration management, performance analysis, virtualization, DNS, security, and the management of IT service organizations. The authors—world-class, hands-on technologists—offer indispensable new coverage of cloud platforms, the DevOps philosophy, continuous deployment, containerization, monitoring, and many other essential topics. Whatever your role in running systems and networks built on UNIX or Linux, this conversational, well-written ¿guide will improve your efficiency and help solve your knottiest problems.

For students, aspiring IT specialists, and working professionals, "Linux Basics for SysAdmin" is a great starting point for learning the fundamentals of Linux, including the command line and all the tools and commands needed to manage enterprise systems. At first, you are introduced to the Linux environment, with a focus on browsing the filesystem, using basic commands, managing files and directories, and becoming acquainted with the shell. You'll also learn about package management and how to handle system startup and shutdown efficiently. After that, you'll learn all about system configuration files, 'systemd' for managing system services, crontab for job scheduling, and 'at' and 'batch' for automating processes. You will also learn about system performance monitoring, log files, backup and restore procedures, disk partitioning, and remote management via SSH. Afterwards, the book delves into topics such as dependency management, system hardware configuration, kernel upgrades, and device driver management, as well as package management with 'apt' and 'yum'. You'll also learn how to create and manage repositories, and install and setup virtual machines with VirtualBox. In the end, the book covers a wide range of topics, including creating and managing user accounts, editing user profiles, setting ownership and permissions for files, using ACLs, managing user sessions, configuring sudo for administrative tasks, implementing password policies, working with PAM, and managing group memberships. An understanding of the basics of Linux system administration will be yours by the time you finish this book. Key Learnings Master essential Linux commands to efficiently navigate and manage the system's file structure. Gain proficiency in user and group management to ensure secure access control and permissions. Learn to configure and manage system services with 'systemd' for streamlined service administration. Implement and enforce robust password policies for enhanced security and user account protection. Understand and utilize package management tools for seamless software installation. Set up and manage virtual machines with VirtualBox to create isolated, reproducible development environments. Use Access Control Lists (ACLs) to fine-tune file permissions beyond the standard Unix model. Schedule and automate tasks using 'cron', 'at', and 'batch' to improve system efficiency and reliability. Monitor system performance and logs to proactively identify and address potential issues. Securely configure and use SSH for remote management and administration of Linux systems.

Book Description
Reveals and illustrates the awesome power and flexibility of the command line, and the design and usage philosophies that support those traits. This understanding of how to extract the most from the Linux command line can help you become a better SysAdmin. Understand why many things in the Linux and Unix worlds are done as they are, and how to apply the Linux Philosophy to working as a SysAdmin. The original Unix/Linux Philosophy presented foundational and functional tenets - rules, guidelines, and procedural methods - that worked well. However, it was intended for the developers of those operating systems. Although System Administrators could apply many of the tenets to their daily work, many important tenets were missing. Over the years that David Both has been working with Linux and Unix, he has formulated his own philosophy – one which applies more directly to the everyday life of the System Administrator. This book defines a philosophy, and then illuminates the practical aspects of that philosophy with real-world experiments you can perform. Inspired by David’s real mentors, and dedicated to them, The Linux Philosophy for System Administrators is a mentor to SysAdmins everywhere; remember - "If you fail you learn." What You Will Learn Apply the Linux philosophy to working as a SysAdmin Unlock the power of the knowledge you already have Fully understand and access the vast power of the command line Review the power of Linux as a function of the philosophies that built it Who This Book Is For If you want to learn the secrets that make the best Linux SysAdmins powerful far beyond that of mere mortals; if you want to understand the concepts that unlock those secrets; if you want to be the SysAdmin that everyone else turns to when the bytes hit the fan – then this book is for you.
