Summary of five experiences that will help you learn the Linux System

At the beginning of Linux learning, I am a little hard to learn because I have no foundation. When I have a certain understanding of Linux, you will constantly adjust your learning methods. When learning Linux, remember to put down your previous thinking and contact Linux with an "ignorant" learning attitude. It may be a good choice. In addition, there is no shortcut to learning Linux. At that time, I chose the entry-level book "Linux should be the case". As long as you study and digest your own things in a down-to-earth manner, there will be no problem.
1. the Linux learning environment that Beginners should have
We need to build a Linux system environment for future exercises. You do not need to purchase a new computer to practice experiments, simulate a simulation system through a virtual machine. Virtual machines allow users to simulate multiple operating systems on a real machine. Generally, the current mainstream hardware configuration is correct. Based on my nearly ten years of experience in O & M Technology and online training, we recommend that you do not install the Linux system on the hardware, regardless of whether the financial conditions permit, because we will inevitably "Toss" your Linux operating system during the learning process. The system created through the Virtual mechanism can not only simulate hardware resources, but also separate the experiment environment from the real machine file to ensure data security, more importantly, when a system exception is caused by incorrect operation or configuration, the system can be quickly restored to the environment status before the error, reducing the waiting time for reinstalling the system.
2. Start with the basics to prevent the use of graphical interfaces
As the saying goes: I don't know how much potential I have without forcing myself. Most Beginners use graphical interfaces because of poor commands. In fact, this is a bad habit, because the real Linux experts or O & M engineers access the command line interface every day. So from the very beginning, I was forced to start with a command-line Linux. I believe that one day you will not regret your previous choice.

3. Learn from the old and learn from the old. Constantly Improve the self-learning ability and expand the depth and breadth of your own.
To have a good self-learning ability, you need to consider how the knowledge points of the teacher can be expanded. At this time, a good Data Book is necessary. We strongly recommend the books you read when getting started, this book is called "Linux should learn this". It has a total of 20 technical chapters. The books are written based on the latest Linux system, and the supporting software and materials are completely free of charge, the course is intended for beginners, starting from the basics and gradually improving the difficulty of the course. Compared with the traditional RHCE training, at least 50% more knowledge is required, as long as you spend 2 hours learning every day, you can see a huge change in a month. The details here are very detailed and highly targeted. They fully cover the latest Red Hat certification content. They can not only learn the actual operating capabilities of Linux, but also easily win the redhat certification, why not:Http://www.Linuxprobe.comLearning is your own business. You must constantly improve yourself and enrich yourself!
4. Beginners do not have to pay attention to depth, but to the breadth.
Do not rush to master all the parameters of a Linux Command. I think it is necessary to clearly understand the basic functions and classification of the command, for example, run the command to view help, common system work commands, system status detection commands, working directory switch commands, text file editing commands, file directory management commands, packaging compression and search commands, etc, sort the command and then classify it. When it is used, first know the type of command it belongs to, and then carefully study the detailed parameters of the command. In general, first understand the overall structure or framework of Linux, and then break through the specific aspects of Linux. In this case, I believe that you will become a Linux master in a sense of accomplishment.
5. Diligent operation and multi-practice, standing at the height of the thinker is the key
Learning is the most difficult to understand. We must practice more and learn to think independently. We used to follow the configuration document given by the teacher when we were studying, I feel that I have mastered it, but after a while, I found a lot of problems only when I re-operate it. Sometimes it is strange why the teacher has no problems when talking about it, so when you are free, move out of the Virtual Machine and run multiple commands and practice diligently. The highest level of learning is that you need to start from different needs and put several services together for comprehensive consideration, for example, in an enterprise architecture, the most important thing is the comprehensive use of LVM, RAID, and disk quotas. We also need to think more about it, and finally conduct experiments and verification in person to accumulate experience.
