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.

Manage complex systems with ease and equip yourself for a new career. This book builds upon the skills you learned in Volumes 1 and 2 of this course and it depends upon the virtual network and virtual machine you created there. However, more experienced Linux users can begin with this volume and download an assigned script that will set up the VM for the start of Volume 3. Instructions with the script will provide specifications for configuration of the virtual network and the virtual machine. Refer to the volume overviews in the book's introduction to select the volume of this course most appropriate for your current skill level. Start by reviewing the administration of Linux servers and install and configure various Linux server services such as DHCP, DNS, NTP, and SSH server that will be used to provide advanced network services. You’ll then learn to install and configure servers such as BIND for name services, DHCP for network host configuration, and SSH for secure logins to remote hosts. Other topics covered include public/private keypairs to further enhance security, SendMail and IMAP and antispam protection for email, using Apache and WordPress to create and manage web sites, NFS, SAMBA, and Chrony. This volume also covers SELinux, and building RPMs to distribute automation scripts. All of these services are installed on a single server host over the course of the book and by the time you are finished you will have a single server that provides these services for your network. What You Will Learn Install, configure, and manage several Linux server services such as email with spam management and single and multiple web sites Work with NTP time synchronization, DHCP, SSH, and file sharing with Unix/Linux and Windows clients Create RPMs for distribution of scripts and administrative programs. Understand and work with enhanced security. Who This Book Is For Those who are already Linux power users – SysAdmins who can administer Linux workstation hosts that are not servers – who want to learn to administer the services provided by Linux servers such as web, time, name, email, SSH, and more.

Explore the world of systemd—yes, all lower-case, even at the beginning of a sentence— which is the modern replacement for init and SystemV init scripts. It is also much more. It can evoke a wide range of reactions from SysAdmins and others responsible for keeping Linux systems up and running. The fact that systemd is taking over so many tasks in modern Linux systems has engendered push-back and discord among certain groups of developers and SysAdmins. You will learn systemd’s strengths and weaknesses, and why there’s no truth in the myth that systemd is a monolithic monstrosity.Learn how systemd is the mother of all processes, and is responsible for bringing the Linux host up to a state in which productive work can be done. You’ll learn about the functions assumed by systemd, which is far more extensive than the old init program, and how it manages many aspects of a running Linux host, including: Mounting filesystems Managing hardware Creating new systemd services and understanding existing ones Creating timers that trigger system maintenance events Starting and managing the system services that are required to have a productive Linux host Using the systemd journal to access critical performance and problem solving information. Why the systemd plan to take over the world is actually a good thing systemd for Linux SysAdmins is your one-stop shop, giving you everythiing you need to get started and utilize this software suite for Linux operatiing systems. You Will Learn: How to use systemd, what it is, and what it does To manage each of the major functional components of systemd and learn from real-world examples to illustrate their typical usage by SysAdmins Pragmatic work-arounds, hints and tricks to minimize issues to ensure you have greater systemd functionality This Book is for: Linux system administrators (SysAdmins) who need to or are already in the process of switching from SystemV to systemd. It’s also intended for SysAdmins with more systemd experience but who want to improve their knowledge and skills with systemd.

Fundamental principles that will keep you on the cutting edge! Most computer architecture books are just too technical and complex. Focusing on specific technology, they often bypass the basics and are outdated as quickly as technology advances. Now, Irv Englander's gentle-but-thorough introduction to computer architecture and systems software provides just the right amount of technical detail you'll need to make successful decisions in your future career. The text covers all the basics in an accessible, easy-to-understand way. Organized in a form that parallels an actual computer system, entire sections are devoted to principles of data, hardware, and software, with computer interconnection, clustering, and networking integrated into the material to emphasize the importance of computer and system structure. Assuming only basic knowledge, these sections build up to an in-depth understanding of each topic and how they interrelate to make up a computer system. With this Third Edition's outstanding features, you'll be able to build a solid foundation for success on the job. All chapters have been thoroughly updated to reflect current technology. Revised with even clearer discussions of virtual storage, the operation of memory, and modern CPU architectures. Programming examples are written in a C++/Java-like pseudocode. Emphasizes the computer aspects of clustering and networking, rather than the data communication aspects. Provide an understanding of underlying, non-changing basics of computers, so that you can make knowledgeable decisions about systems. Introduce new technological concepts without overwhelming you with too much detail. Examples cover a broad spectrum of hardware and software systems, from personal computers to mainframes. Integrates discussions of hardware and software throughout, and explores the symbiosis between them.
