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.

This book explains cloud computing and microservices from the perspective of technological evolution, showing the ins and outs as well as the causes and consequences of cloud computing and microservices. The essence of cloud computing is to deepen resource sharing to improve cost-effectiveness by economies of scale and intensification. From a historical perspective, this book summarizes the 2 leaps of the computing paradigm: from stand-alone computing to cluster computing, and then from cluster computing to cloud computing. On the basis of cluster computing, cloud computing has to further solve two key problems : 1) application programs can run everywhere on the cloud; 2) application programs running on the same computer do not interfere with each other. Cloud computing has promoted informationization, bringing about new challenges to servers. Servers are facing the double pressure of increasing data volume and client requests, with the issue of service quality becoming increasingly critical. In this situation, the strategies and methods for servers to achieve efficiency, resilience, scalability, availability, security and consistency, as well as rapid development, rapid revision and upgrade, and fast startup are collectively known as microservice technologies.

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.

This IBM® Redbooks® publication is Volume 2 of a five-volume series of books entitled The Virtualization Cookbook for IBM Z®. This volume includes the following chapters: Chapter 1, "Installing Red Hat Enterprise Linux on LNXADMIN" on page 3, describes how to install and configure Red Hat Enterprise Linux onto the Linux Administration server, which performs the cloning and other tasks. Chapter 2, "Automated Red Hat Enterprise Linux installations by using Kickstart" on page 37, describes how to use Red Hat's kickstart tool to create Linux systems. This tool is fundamentally different from cloning in that an automated installation is implemented. You can try kickstart and cloning. Understand that these applications attempt to accomplish the same goal of quickly getting Linux systems up and running, and that you do not need to use both. Chapter 3, "Working with subscription-manager, yum, and DaNdiFied" on page 47, describes how the Red Hat Network works. It provides centralized management and provisioning for multiple Red Hat Enterprise Linux systems. Kickstart is an easy and fast way to provision your Linux guests in any supported Linux platform. It re-creates the operating system from the beginning by using the kickstart profile configuration file that installs the new operating system unattended. It also sets up the new guest according to the definition that was set up in the kickstart file. Usually, Linux is administered by the same team that manages Linux on all platforms. By using kickstart, you can create a basic profile that can be used in all supported platforms and customize Linux profiles, as needed. Cloning requires a better understanding of the z/VM environment and z/VM skills. It is a fast process if you enable the IBM FlashCopy® feature in advance. It clones the disks from a golden image to new disks that are used by the new Linux guest. The process can be automated by using the cloning scripts that are supplied with this book. It is recommended that you start with The Virtualization Cookbook for IBM Z Volume 1: IBM z/VM 7.2, SG24-8147 of this series because the IBM® z/VM hypervisor is the foundation (or base "layer") for installing Linux on IBM Z.
