0.1 Introduction to the author of this book


May 23, 2021 That's what Linux should learn



The author of the book, Liu Chuán, who worked in Linux operations Liu Chuán came into early exposure to Linux systems in high school, driven by interest, and began to learn RHCE 6 and 2012 received the Red Hat Engineer RHCE 6 version 2015 the Red Hat Engineer RHCE 7 version certificate and the Red Hat RHCA Certificate.

Nevertheless, I still know that the level is limited and the technology is generally, if not thanks to the selfless help of mentors and friends, certainly can not achieve the above results so smoothly. A nd, as an ordinary tech guy, I've experienced first-hand the heartache of being in a training course in the middle of the 6 congestion, and the fact that I've Linux technology books on the market, which has strengthened my belief in writing this book. At this moment, I am carrying a heart, do my best to share useful knowledge to the reader, I hope you can take fewer detours, faster Linux system.

Stealing thought that a skilled tutor should not only be a skilled porter, but should be a high-quality knowledge of the refiner, so in the process of writing this book, I do not want and will not know all the technical knowledge they know in the book, so as to dazzle skills, but from a really close to the new learning characteristics of the point of view, take the initiative to abandon the unworkable part, and the focus, difficulties repeated practice, in order to deepen the reader's understanding of the theoretical basis, and thoroughly grasp the technical content used in the production environment.

This book is based Linux RHEL 7 and the supporting software and materials are completely free, with courses Linux nods. T his book takes the reader to the Linux system Linux basis, and then gradually makes the content more difficult to match the requirements of the production environment for operations personnel. M oreover, each chapter of this book is equipped with a large number of diagrams, tables, command examples, and after-school exercises to enhance the reader's interest in learning and deepen memory. Finally, this book and supporting resources are at least 40% RHCE training, as long as you can keep learning every day, I believe this is definitely the best and fastest progress you can experience.

Finally, I would like to say that my writing intention is not elegant, just in debt repayment, but also more than a decade china has so many training institutions made so much money, but no training institutions really provide students with a good teaching material debt, and this should be our students should have enjoyed the service, can no longer selective blindness. A nd in 2017 my original intention of writing is also a little private, in addition to running the "Linux should learn" book online learning site https://www.linuxprobe.com, to serve more students and readers, but also to our free open source books far more than other training institutions charge materials The level, and adhere to do China's open source site moral model, do not deceive, do not do evil, maintain the purest technical communication environment, and we want to get is very simple - if you recognize the pay of Mr. Liu Wei and satisfied with our service, but also please tell the book to friends around, so that more people know that we are doing this cool thing.
