Linux system is a set of operating system composed of Linux kernel and open source free software. It is a kind of UNIX-like system. Its kernel was first released by Linus Torvalds on October 5, 1991.
Its main features: Linux files are all files, completely open source and free, support multi-user and multi-task, and also support multiple architecture platforms, reliable security, good stability, powerful network functions, diverse graphical interfaces;
In recent years, the Linux system has gradually attracted many people. It is precisely because of its power that it supports huge projects and continues to affect the lives of most people. In fact, everyone is not unfamiliar with Linux systems, and they have been in touch with it more or less, because you are everywhere around you.
For example, the Android phones and tablets you use now, ATMs, set-top boxes, on-board computers, flight control systems, Internet giant cloud services, and even the government are using Linux systems. The above is my understanding of Linux systems. Compared with other operating systems, its advantages make it worth learning. Besides, not to mention the wide range of application scenarios. The current Internet giants (BAT, Sina, Netease, JD, etc.) all use Linux systems, all of which reflect its advantages. Where.
When it comes to learning Linux, I believe everyone has their own methods, but the basic introductory stage is not enough, and it is not competent for more complex tasks. How to learn Linux system better? Everyone should have a different point of view, without exception, the ultimate goal is to learn how to use, learn the essence of Linux, the method is very important:
1. Choose a release system
It is not recommended to use other distributions. If you can use one distribution proficiently, other distributions are not too problematic, but the commands are different. Please don’t entangle on this issue, as if you say "PHP is the world "The best language" is the same. Don't waste time choosing the release version.
2. Choose a book or tutor that is more suitable for getting started
A good book can make learning more effective, and a good tutor can make Linux learning easier. I personally feel that the children's shoes for learning Linux at the beginning should be easier to get started, the content is concise, the explanation is thorough, and the choice is suitable for you Books, you can go to the Internet to search for basic entry-level Linux books of related types, usually in electronic versions.
3. Practice more, learn to summarize and think
Because learning every technique is constantly imitating and then imitating on the wheels made by others, only by practicing more can you understand the principles and memorize it through understanding, so that you can learn quickly.
If you don’t understand, you must check the information, be good at using search engines (Baidu/Google), learn systematically, practice more, thoroughly do the experiments in the book, master the principles, and then summarize, check for omissions, and fill vacancies. It’s also important to think about it. Don’t just study, but also think about the application scenarios of this technology, the principles used, etc., and think more about why.
4. Starting from the basics, facing difficulties
Linux skill points: Linux system basics—Linux system management—Linux service management—Linux security management and prevention—Linux advanced operation and maintenance—Linux operation and maintenance automation...
Here is just a brief introduction, far more than that. I hope we can cheer together. When you really get started, you will have more exposure and a deeper understanding of the industry. There is more to learn, and you can set more for yourself. Many goals, when you finish learning these, you will have a better help in your future career.
5. Career development direction
In fact, after learning Linux technology, there are many development directions. For now, it is relatively easy to find a job: Linux operation and maintenance, Linux operation and maintenance architect, Linux operation and maintenance automation, Linux development, DevOps and other positions, according to your own grasp The Linux technology has positioned itself for a development direction and has been working hard. If you want to better improve yourself and get a higher salary, you can take the Red Hat certification, which is still very useful for future work.
6. Technological innovation
For the continuous innovation of IT technology, the development speed is very fast. How to become a strong and not be eliminated by society requires us to improve our own capabilities. In recent years, it has been very popular: OpenStack, Doctor, Kubernetes, cloud computing, and also need Mastering a development language: Python, shell, golang (one of them), etc., are skills that we need to learn by ourselves and constantly adapt to the needs of the company/enterprise in order to be more competitive.
The content is personal opinion. Welcome everyone to leave a message to share your knowledge of Linux and learn together. As long as you have your own plans and goals, and stick to it, I believe we will definitely go further and further on the road of Linux and become the strong. Come on!
