Shulou(Shulou.com)06/02 Report--

My university major is computer technology and application, that is, the so-called everything, nothing can be learned. When I was in school, I didn't have a sense of crisis. I was confused for three years. I didn't know the feeling of regret until I was looking for a job after graduation. unfortunately, there is no medicine for regret in the world, so I can only swallow the bitter water into my stomach.

Until one time when I was looking for a job, I saw a company recruiting operation and maintenance staff to try and get to know the interviewer. Luckily, they were willing to try it for three months, and then they formally took the first step in their career. They only came into contact with linux during the internship, and then followed Master to learn more about linux step by step. I also share some of my views with you with my six years of operation and maintenance experience and learning linux experience. Of course, in the IT industry, sharing is a spirit and a virtue.

First: master the Linux command line

The essence of Linux lies in the skilled use of commands, no matter what level of graphical interface development this will not change the truth, Linux commands have many powerful features: from simple disk operations, file access, to complex multimedia images and streaming media file production, can complete very complex operations, if the same operation with graphical interface tools to complete, I am afraid it will take a lot of time. .

Beginners only need to master some of the more important and frequently used commands, later you will encounter more difficulties, but also one by one to break down, step by step. According to their role in the system is divided into several parts, through the study of these basic commands, we can further understand the Linux system:

Installation and login commands: login, shutdown, halt, reboot, mount, chsh

File processing commands: file, mkdir, grep, dd, find, mv, ls, diff, cat, ln

System management related commands: df, top, free, quota, groupadd kill, crontab, tar, last

Network operation commands: ifconfig, ip, ping, netstat, telnet, ftp, route, rlogin rcp, finger, mail, nslookup

System security related commands: passwd, su, umask, chgrp, chmod, chown, chattr, sudo, pswho

Second: choose a learning reference book that is always around.

Reference books are very important for learning, just choose what suits you, but I must stick to it. I recommend the book "Linux should learn this way". It is written in a popular way, and the most important thing is free, so the online reputation for this book is also very good, but choose what is suitable for you is the best, do not follow others.

Third: which Linux version platform to learn from?

At present, there are more than a hundred Linux distributions worldwide, written by individuals, loosely organized teams, as well as commercial and volunteer organizations. How to choose according to your needs and capabilities, domestic enterprises use RHEL, Centos system is the most, for beginners, the author still recommends the use of Centos.

Fourth: make yourself like the command line.

Whether in terms of efficiency or ease of use, native Shell (CLI) is easier to use. Of course, the progress of learning under the command line is slow at first, but after you are familiar with it, the future learning path will grow exponentially. As far as the network administrator is concerned, the command line is actually a rule, and if you follow it, it will pay you back in time. Give up your winows thinking for a while and devote yourself to linux thinking. At the same time, this is one of the conditions that a qualified Linux network administrator must have.

Fifth: be diligent in doing experiments by yourself

One's own Linux operation skills can only be improved through hard work and hard work. Experience is important because it can solve problems more accurately and efficiently, and where experience comes from repeated experiments that enable you to grow quickly or give full play to your talents in the workplace.

Sixth: be good at consulting experts when you have no choice.

In the process of learning linux, it is too normal to encounter a lot of problems that you can't solve by yourself, so don't be discouraged when you can't solve them by yourself. There are always more ways to solve problems than problems:

In fact, Linux has its own detailed documents (including man pages and FAQ), but they are all in English, from system installation to system security, detailed documentation for people at different levels, read the documents carefully, combined with your thinking and analysis ability, I think most of the problems can be solved. Of course, consult the reference books and relevant forums in linux can also find solutions to the problem, but also have a certain reference value.

Ask for help in the Linux forum, as long as you think carefully and describe your problems. The more you show your efforts to solve the problem before you ask for help, the more substantial help you will get. It is best to search the forum to see if there are any articles you need, so that you can get twice the result with half the effort.

The above are some of my own learning ideas, I believe everyone has their own set of learning ideas, this article is for reference only.

Finally, I hope all linux operation and maintenance personnel can stay on the road of Linux for a longer time!
