A learning approach and roadmap that Linux systems deserve to see

Network is a very magical thing, modern life can not be separated from the network, the network has been deep into people's work, life, entertainment and other aspects. The network is everywhere because it provides a lot of network services, so network service is the soul of the network.

Various network services on the Internet are architected on a variety of servers. A server is a physical vehicle that provides network services and is a computer, but it is a more powerful computer, especially in the area of Web application services. The operating system is installed on the server, as is the case with Windows 7,windows 8 or Windows 101 installed in a normal PC. The operating system running in the server is commonly referred to as the server operating system or the network operating system. Network operating System management of the Internet in a variety of services: dhcp,ftp,web,e-mail,dns, streaming media, network games, no network operating system, people will not be able to enjoy a variety of network services. Currently the main network operating system has Windows and Linux two kinds.

The Linux operating system has developed very rapidly within a few years, which is inseparable from the good features of Linux. Linux contains all the functions and features of UNIX. In short, Linux has the following main features: Following the GNU GPL, openness, multitasking, multiuser, device independence, providing rich network functionality, reliable system security, and good portability.

As a computer major is also a high vocational students when I first contact with Linux is based on Redhat 6.2, (at that time only know that Windows does not know what Linux is) because there is no foundation, it is difficult to learn, So when the teacher told a new knowledge point always keep up with the rhythm, face the black screen white and the teacher's fast rhythm I have to use more time to learn Linux in class. In the process of self-study will inevitably encounter large and small problems, in accordance with my knowledge of the level is not solve these problems, only Baidu to solve the problem (but the degree Niang is not omnipotent), until the opportunity to meet the coincidence of my study on the road of the Mentor "Linux should learn" this book, Liu Yan teacher wrote, Content enrichment, literary humor, illustrations, technology more practical, learning more relaxed, the most critical is the online learning resources, but also Liu Yan teachers help you to dispel your questions. As a beginner to learn Linux this book is very user-friendly from the first chapter tells how to learn Linux correctly, then teach you to learn Linux to lay a solid foundation-to deploy a virtual environment to install the Linux system, easy-to-go, like building a high-rise as the first to lay the foundation and then step-by-step climb. Day by day you are the Linux Daniel (hahaha). I think I need to share my experience with the basics of Linux:

1 , mastering Linux Basic

As the saying goes, "think is ready, be prepared," before you learn to build a good learning environment (Red Hat RHEL7) and then install it on the virtual machine, to start using it. Learning Linux, command use is a prerequisite for learning, just as you speak to a foreigner, you have to speak English or else how people know what you are talking about. For example:

command names, options, and parameters are all input items of the command, and they must be separated by a space. The command format for Linux is as follows:

Command name "Options" "Parameter 1" "Parameter 2" ...

Learn Linux, to master the use of commands, although many commands, but practice practice, in the future of the use of learning can greatly save your time. and learning Linux must not be careless, often a small space will be error, of course, in Linux, the case is very sensitive, remember!

2 , starting from the foundation, do not above his business

Linux if after a period of study you will find that it is not so difficult to imagine, or even simpler than Windows has been manipulated, usually think that Gli does not Gul that aspect of user action. Because the command line interface software usually requires user memory operation to complete the command, however, because of its own characteristics, the command line interface to save the computer system resources than the graphical user interface. So, with the premise of memorizing commands, using a command line interface is often faster than using a graphical user interface, which is one of the basic conditions for you to play Linux later.

3 , more summary, diligent thinking, take notes

If you want to learn Linux system knowledge, not a day or two days can learn, but also through overnight, slowly accumulate, the process should learn to summarize, think more, more hands to practice, to practise, on the basis of understanding of memory, the principle to understand, the important knowledge points accumulated, so that in the future work to facilitate the search , as a query manual, but also can exercise our ability to write documents, it will be a great help in the future.

4 , recharge in time, improve self-study ability

To have a good self-study ability, in addition to the teacher said, you have to consider the teacher's knowledge points can also how to expand, at this time a good information book is very necessary, suggest you see "Linux should Be so learned", beginners must read books, fresh content, nonsense little, in addition to these basic all learned, It is recommended that you further study the advanced technology of Linux, and constantly improve yourself.

The above is just my personal learning experience, I hope that my learning experience can help to like my original such a novice. Learn Linux Foundation to be solid, must not be ambitious, down to practice thinking. The rhythm of your fingertips and thoughts can jump out of the Linux waltz!
