Editor to share with you what are the basic knowledge points of the Linux system, I hope you will gain something after reading this article, let's discuss it together!

The network is a very magical thing, modern people's life is inseparable from the network, the network has gone deep into people's work, life, entertainment and other aspects. The reason why the network is everywhere is that it provides many network services, so the network service is the soul of the network. All kinds of network services on the Internet are built on a variety of servers. Server (Server) is the physical carrier to provide network services, is a kind of computer, but it is a more powerful computer, especially in network application services. There is an operating system installed on the server, just like Windows 7 and Windows 8 or Windows 10 are installed in a regular PC.

The operating system running in the server is often called the server operating system, or the network operating system. The network operating system manages a variety of services in the Internet: DHCP,FTP,Web,E-mail,DNS, streaming media, online games and so on. Without the network operating system, people will not be able to enjoy all kinds of network services. At present, there are two mainstream network operating systems: Windows and Linux.

Linux operating system has developed rapidly in just a few years, which is inseparable from the good characteristics of linux. Linux contains all the functions and features of UNIX. To put it simply, linux has the following main characteristics: following GNU GPL, openness, multi-tasking, multi-user, device independence, rich network functions, reliable system security and good portability.

As a computer major and also a higher vocational student, my first contact with linux was based on redhat 6.2. at that time, I only knew that Windows did not know what Linux was. Because there was no foundation, it was very difficult to learn, so when the teacher talked about a new knowledge point, I always couldn't keep up with the rhythm. In the face of black screen white words and the teacher's fast pace, I had to spend more time after class to learn linux. In the process of self-study, we will inevitably encounter large and small problems. According to the degree of my knowledge reserve at that time, we could not solve these problems. Only Baidu solved the problems (but du Niang was not omnipotent). Until I met my mentor "Linux should learn this way" by chance, the book, written by teacher Liu Han, was full of content, humorous, graphic and textual, and the technology was more practical. Learning is relatively easy, the most important thing is to have the online learning resource http://www.linuxprobe.com/tools, but also to have Mr. Liu to help you solve your problems. As a novice to learn linux, this book is humane to tell you how to learn linux correctly from the first chapter, and then teach you to lay a solid foundation for learning linux-- deploy a virtual environment to install linux system, from shallow to deep, just like building a tall building, first lay the foundation and then climb step by step. Day by day you are linux Daniel (ha ha). I think I need to share my basic experience of learning linux:

1. Master the basics of Linux

As the saying goes, "if you think, be prepared." before you learn, you should set up a learning environment (Red Hat RHEL7) and then install it and start using it. To learn Linux, the use of commands is a prerequisite for learning, just like when you talk to foreigners, you have to speak English or others will not know what you are talking about. For example:

The command name, options, and parameters are all independent entries as input to the command, and they must be separated by a space. The format of the command in Linux is as follows:

Command name [option] [Parameter 1] [Parameter 2].

To learn Linux, to skillfully master the use of commands, although there are many commands, but practice makes perfect, in the future study and use can greatly save your time. And learning linux must not be careless, often a small space will report errors, of course, in linux, case is very sensitive, remember!

2. Start with the basics, do not aim high and do not have low skills

Once you have studied linux for a period of time, you will find that it is not as difficult as you think, and it is even easier to operate than windows. It is generally believed that GLI is not as user-operated as GUL. Because the software of the command line interface usually needs the user to remember the operation to complete the command, but because of its own characteristics, the command line interface saves the resources of the computer system than the graphical user interface. Therefore, under the premise of memorizing commands, using the command line interface is often faster than using the graphical user interface, which is one of the basic conditions for you to play Linux in the future.

3. Summarize more, think hard, and take more notes

If you want to learn the knowledge of Linux system well, you can not learn it in one or two days, but also accumulate it overnight. In this process, you should learn to sum up, think more, practice more, practice more, memorize on the basis of understanding, understand the principle, and accumulate important knowledge points, so that you can easily find them in future work as query manuals. At the same time, you can also exercise our ability to write documents. It will be of great help in the future.

4. charge in time to improve the ability of self-study.

To have a good self-study ability, in addition to what the teacher said, you also have to consider how the teacher's knowledge can be expanded. At this time, a good material book is very necessary. I suggest you take a look at "Linux should learn like this". Beginners must read books with fresh content and little nonsense. In addition, I have learned these basics. I suggest you go in depth to learn Linux advanced technology and constantly improve yourself.
