Summarize four helpful methods for learning Linux system, the specific contents are as follows

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.

So, how should we learn the Linux system correctly?

1. Master the basics of Linux

You have to pick a distribution system that suits you, install it in the virtual machine, and start using it. If you want to learn Linux quickly, my advice is to forget about the graphical interface, not whether it can provide answers to your questions, but to find, ask, and use the command line to solve your problems all over the world.

In this process, you'd better master the Linux commands well, at least know the most commonly used commands, and set up your own knowledge base, which contains all the knowledge you have accumulated.

2. Start with the basics and put an end to the use of graphical interfaces

Once you learn Linux for a period of time, you will find that it is not as difficult as you think, or even easier than windows. Friends who have studied linux all know that linux has an init running level, 0 is to shut down the system, 1 is single user mode, and broken password is in this mode. 2 is a character interface without network, similar to the security mode without network on windows, and 3 is a full-featured CLL mode. Similar to windows's security mode, 4 has no specific definition, 5 is a graphical interface, and 6 is a restart mode. Beginners because the command is not very good so that most of them use the graphical interface, in fact, this is a bad habit, when you are familiar with the operation, you will feel that the command mode is more convenient.

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 should also consider how the teacher's knowledge can be expanded and constantly improve yourself.

The above is just my personal learning experience. I hope my learning experience can help a novice like me. To learn linux well, we should have a solid foundation. We must not aim too high and practice thinking in a down-to-earth manner.

Fingertips and the beating of the mind can jump out of the linux waltz!
