Automating Linux and Unix System Administration, 2/e (Paperback)

Whether you need a network of ten Linux PCs and a server or a datacenter with a few thousand Unix nodes, you need to know how to automate much of the installation, configuration, and standard system administration.

Build your network once using cfengine, and the network build will work, without user intervention, on any hardware you prefer. Automating Linux and Unix System Administration, Second Edition is unique in its focus on how to make the system administrator’s job easier and more efficient: instead of just managing the system administrator’s time, the book explains the technology to automate repetitive tasks and the methodology to automate successfully.

• Both new and seasoned professionals will profit from industry–leading insights into the automation process.
• System administrators will attain a thorough grasp of cfengine, kickstart, and shell scripting for automation.
• After reading all chapters and following all exercises in this book, the reader will be able to set up anything from a Linux datacenter to a small office network.

What you’ll learn

See how to make changes on many UNIX and Linux hosts at once in a reliable and repeatable manner.

• Learn how to automate things correctly so you only have to do it once, by leveraging the authors’ experience in setting up small, medium, and large networks.
• Set up a Linux datacenter or a network correctly.
• Explore handling real–world environments where not all hosts are configured alike via a case study of a fictional new datacenter buildout.
• Examine real–world examples for core infrastructure services (DNS, mail, monitoring, log analysis, security, cfengine, imaging) to build on in your environment.
• Understand core system administration best practices, which are a key part of how cfengine and automations deployments are outlined in the book.
• Learn how to make changes reversible, repeatable, and correct the first time through interaction with product/application stakeholders (programmers, product managers, customers, etc.).

Who is this book for?

This book is for Linux system administrators who want to learn about the software and methodology to automate repetitive tasks—regardless of network or datacenter size—in one place. System managers will also find it much easier to think about network technology and automation projects if they read this book. This book is also for anyone who is interested in repeatable and secure infrastructure.

無論您需要一個由十台Linux個人電腦和一台伺服器組成的網路，還是一個擁有數千個Unix節點的資料中心，您都需要知道如何自動化大部分的安裝、配置和標準系統管理工作。

使用cfengine建立您的網路一次，並且該網路建置將在任何您喜歡的硬體上自動運作，無需使用者介入。《自動化Linux和Unix系統管理，第二版》在專注於如何使系統管理員的工作更輕鬆和高效方面獨樹一幟：該書不僅僅解釋了如何管理系統管理員的時間，還解釋了自動化重複性任務的技術和成功自動化的方法論。

無論是新手還是經驗豐富的專業人士都將從行業領先的自動化過程見解中受益。

系統管理員將全面掌握cfengine、kickstart和shell腳本編寫以實現自動化。

閱讀本書的所有章節並完成所有練習後，讀者將能夠建立從Linux資料中心到小型辦公網路的任何系統。

您將學到什麼：

- 看到如何以可靠且可重複的方式在多個UNIX和Linux主機上進行更改。
- 通過利用作者在建立小型、中型和大型網路方面的經驗，學習如何正確自動化事物，以便只需執行一次。
- 正確地建立Linux資料中心或網路。
- 通過虛構的新資料中心構建案例研究，探索處理不同配置的真實環境。
- 通過核心基礎設施服務（DNS、郵件、監控、日誌分析、安全、cfengine、映像）的真實案例，為您的環境搭建基礎。
- 理解核心系統管理最佳實踐，這是cfengine和自動化部署在本書中概述的重要部分。
- 通過與產品/應用利益相關者（程序員、產品經理、客戶等）的互動，學習如何使更改可逆、可重複且第一次就正確。

這本書適合誰閱讀？

這本書適合想要在一個地方學習有關軟體和方法論以自動化重複性任務的Linux系統管理員，無論網路或資料中心的大小如何。如果系統管理員閱讀了這本書，他們也會發現思考網路技術和自動化項目變得更容易。這本書也適合對可重複和安全基礎設施感興趣的任何人。
