What books do Linux O M engineers recommend?

You can read these five books: "Learn Linux O&M Web Cluster Practice with Old Boys", "Learn Linux O&M Shell Programming with Old Boys", "Learn Linux O&M Core System Command Practices with Old Boys", "Learn Linux Core Basics with Old Boys (Part I)", and Learn Linux O&M MySQL Introduction and Improvement Practice with Old Boys

If you get started with linux, you should learn this way when you watch "linux", and Brother Bird's private dish is a sleeping artifact.

1.Operating system status monitoring.

Log in to the system every day to check the load of the system and check whether there are error logs or alarm logs.

2.Operating system troubleshooting.

Analyze the cause of the alarm or error based on the operating system fault log to solve the problem and ensure the high availability of the operating system.

3.Server status confirmation.

In addition to running the operating system, some applications or databases will inevitably be installed on the server, and the operation and maintenance engineer needs to check whether the application or database running on the Linux system is normal every day.

4.Backup. Generally speaking, as long as the database is backed up by itself, as long as the backup policy is formulated for the database, it will back up by itself, and you only need to monitor whether the backup task is executed.

5.Server tuning.

This requirement is relatively high, as the state of Linux will decrease with the growth of use time, and the operation and maintenance engineer has the ability to optimize the performance of the operating system and database to ensure that the system is in an optimal state.

Generally speaking, the work of O&M engineers is mainly monitoring, and they will only deal with problems when they occur, which is usually very easy. I'm in charge of the operation and maintenance of six servers for three information systems, which is quite easy.

What do you say about this cave attack question? Very ambiguous. Whether it's good or not, first of all, you need to understand, learn, and then work, only in the work, will you really understand whether Linux operation and maintenance is good or not, everyone's work level is different, and the view on this issue is different, in fact, it depends on your understanding of work, if you work well, then you must say that Linux operation and maintenance is easy to do, if you don't work well, don't make money, you may abandon this industry!

In fact, from the perspective of the industry, Linux operation and maintenance is a good job!

Choosing Linux is the trend of the times.

Linux technical support is extensive, open-source, stable, and efficient, providing platform support for big data, cloud computing, and the Internet of Things, which will never go out of style.

Linux O&M salary is relatively high!

Linux O&M is an increasingly popular industry, and your salary may only be seven or eight thousand at the beginning, but don't worry, it's good later, and the longer the working life of Linux O&M, the more popular it is. Don't worry, it's a youth meal!

Okay, I'm sharing a learning roadmap for the overall knowledge of Linux O&M!

Linux Learning Roadmap.

Practice the basics.

1.Familiar with Windows and Linux operating systems; Operating system principles are the essence.

2.Familiar with the use of SED, AWK, GREP and other scripts; Regular expressions are familiar.

3.Common systems should be familiar with the deployment of Windows and Linux. For example, DNS, FTP, Web, MySQL, MSSQL, etc.

4.The basic configuration of switches and firewalls should be known.

Recommended: abs guide cn Script basics.

Brother Bird's private dishes, components of high-performance web site; And then all sorts of other books that focus on programming, on databases, ......

The above is only for the operation and maintenance, if you want to enter the financial state-owned enterprises and other industries, please ignore the ......

1.Linux System Administration Technical Manual (2nd Edition) — Learn the basics, practical knowledge of Linux.

2.Linux Shell Programming & Server Management - A very simple introductory shell textbook, a must-see.

Intermediate and advanced shell textbooks, a must-see.

4.Component high-performance web site - a must-see for operation and maintenance.

O&M here is based on desktop O&M, followed by server-related and network-related aspects, of course, it also depends on whether you want to go to the technical side, or basic O&M, and the technical aspect is still development-oriented, various languages.

In terms of operation and maintenance, there are no classic books yet. However, it is recommended to learn Linux well: "Brother Bird's Private Dishes" and other main things depend on your work and work experience accumulation, after all, operation and maintenance is something that has come out in recent years.

Building a Web High-Performance Architecture" and "Building a High-availability Linux Server", but it is better to have a little knowledge of Linux and shell in the future.

Brother Bird's private dish, learn Linux from Ah Ming, Linux should be learned like this.

Look at Brother Bird's Linux private dishes, which is a must-see for all O&M.

1. Solid basic skills and Linux cognition.

Brother Bird's Linux Private Dishes This book is suitable for Linux learners with 0 foundation, and you can use this book as a starting point for systematic and comprehensive learning, of course, this learning cycle will be relatively long.

2. Apply ability knowledge reserve and hands-on practice.

Linux should be learned like this" is a good book, he abandoned some of the basic learning of Brother Bird's book, and paid more attention to the skill learning and practice of operation and maintenance applications, and there are rich learning resources and a complete ecosystem. For hands-on practice, it is recommended to install a virtual machine on the machine for learning, or to study in chapters in the laboratory building.

3. Deep learning and actual combat.

There is a little bit of foundation, what is the foundation, please be specific.

<> found a more detailed course chart, I hope it will be helpful to you.
