Description

Red Hat Enterprise Linux is an operating system that allows you to modernize your infrastructure, boost efficiency through virtualization, and finally prepare your data center for an open, hybrid cloud IT architecture. It provides the stability to take on today's challenges and the flexibility to adapt to tomorrow's demands. In this book, you begin with simple troubleshooting best practices and get an overview of the Linux commands used for troubleshooting. The book will cover the troubleshooting methods for web applications and services such as Apache and MySQL. Then, you will learn to identify system performance bottlenecks and troubleshoot network issues; all while learning about vital troubleshooting steps such as understanding the problem statement, establishing a hypothesis, and understanding trial, error, and documentation. Next, the book will show you how to capture and analyze network traffic, use advanced system troubleshooting tools such as strace, tcpdump & dmesg, and discover common issues with system defaults. Finally, the book will take you through a detailed root cause analysis of an unexpected reboot where you will learn to recover a downed system.

Who is this book for?

If you have a basic knowledge of Linux from administration or consultant experience and wish to add to your Red Hat Enterprise Linux troubleshooting skills, then this book is ideal for you. The ability to navigate and use basic Linux commands is expected.

This guide is awesome, it is precise when needed and also gives perspective with general explanation when needed . Obviously author draws from his own experience but principles and solutions are applicable to any red hat linux setting.Absolutely recommended for those working with linux on daily basis as well as for the aspiring admin. I'm also using this book as a resource to prepare for Red Hat's CoE Diagnosing and Troubleshooting RHEL 7.

The author guides us step by step (and precisely) to explore most of the possible ways to analyze a given problem. And this is why it's not a book as the others...This book is a part of few books that we buy blindness, to say to himself then that we have for his money, and very widely...Then, we would like that the author writes a book every day! I really greet this author...I'm looking for a similar book on Linux/Network security...

Red Hat Enterprise Linux Troubleshooting Guide may just be all you need in your quest to wear the red hat. May I remind you that this is not a "getting started guide", but a troubleshooting guide. This assumes you are somewhat familiar with Red Hat Linux and you may be having difficulty with a particular scenario. If that's your situation, then this book IS your book.The information is organized well with respect to topics and real world scenarios and the appropriate solutions. I found that most of the principles described behind the scenarios could be generally used to troubleshoot other Linux environments as well; which makes this book even more valuable.I think a book like this should be written for every OS that exists.

Working with Red Hat daily so this book was a no brainier of a purchase, since Packt has a global $5.00 sale right now on all of their books. The book has a nice flow, and all of the information was well received. I enjoyed the section on tcpdump, and the coverage on /dev was on point. I highly recommend this book not only for Red Hat, but it's pertinent to Centos and you can even tweak it enough to get away with doing some diagnostic work on Debian based Linux distributions.
