Graduated in 2010, has been engaged in the IT industry for nearly 7 years, along the way there are many shortcomings, whether in technology or in the work of dealing with people, etc., but it is these deficiencies that make me have the present progress, technology from the initial crystal head, integrated cabling to server shelving, network equipment debugging, service installation, etc., from managing one network device to managing hundreds of devices In the position, from network management to system engineer, and then to technical support, I have experienced all kinds of projects. Immodestly, I can be counted as a senior operation and maintenance engineer, and there are many friends around me who often discuss technology and work with me. Problems in life. The purpose of writing this article is to extract some lessons from my own experience from an IT rookie to a senior engineer to help some IT novices in need. So welcome everyone to communicate and discuss with me!

One of the advanced secret books: gathering sand into a tower

Because the university chose the computer major and needed to learn the basic C language, although I felt that learning computer was the feeling of being a hacker when I signed up for my major at that time, C language really hit me in the head. I still don't know anything after learning with my teacher for a long time, and every time I want to learn, I feel that I can't understand the meaning of the book because I have no foundation. So I gave up over time, and of course the school final exam failed. When I got the first make-up exam in college, I thought about learning C language well. After all, it was the basic knowledge of programming, so I took advantage of the holiday. I calmed down to see the C language for a month, and I got 90 points in the make-up exam later, and when I saw the knowledge points that I didn't understand at the beginning. It is found that the meaning of the knowledge point has been clearly understood. I believe you must have had a similar experience, for example, when you read a textbook in junior high school, you will feel that you may not be able to learn it. Although the college exam doesn't mean anything, it tells me a truth: when you learn a new technology, you may not have a particularly smooth learning experience, and there is a lot of knowledge that is step by step. at this time, we need to calm down. slowly eat through these knowledge that you can't understand for the time being, only when you slowly "gather sand" will you feel Mauseton open one day. At this time, it is the time to "build a tower" and shows that you have made some achievements in your study. I hope that the newcomers who are engaged in IT work or those who are ready to join the profession will not have too many technical concerns and think that they are not graduated from the IT industry. In fact, no matter in that industry, not everyone graduated from the technical class. I know a lot of people who do not graduate from the technical class, and some even have nothing to do with the IT major. Enter IT this line, need you to calm down, precipitate yourself, "gather sand into a tower"!

The second secret book of advanced level: the combination of learning and thinking.

In the first secret book, it is said that the curve of learning will be steep, so some knowledge points will not be understood and need to be solved by accumulating knowledge on their own, but it does not mean that they read books foolishly over and over again, and sometimes they need to think about themselves. what is the basic concept of this knowledge point? The purpose of this knowledge point is to solve what problems and so on. Always pay attention to the combination of learning and thinking. If you look at the knowledge you do not understand many times, if you do not think about it yourself, you will never understand. As the ancients said, "learning without thinking is labor lost, and thinking without learning is perilous." With a good foundation in the subject of operation and maintenance, your road of learning will only get faster and smoother. Ten thousand tall buildings rise from the ground, and no matter how tall the building is, you need to lay a good foundation in order to be stable, and the operation and maintenance staff are also the same. only with a good foundation and learning more advanced knowledge, will you understand faster, more thoroughly, and master more firmly! For example, if you can't even remember the basic linux commands, how can you quickly build server clusters, high availability environments, etc., let alone understand the mysteries?

Advanced secret book number three: learn to ask questions.

Even if you have done all the above two points, sometimes you still encounter all kinds of strange problems, and the process of solving the problem is painful, because very often you can only solve the problem on your own without the help of others. At this time, all the books, materials, or search engines on hand have become your problem-solving tools, in today's society where communications are so developed. I believe you must have added a variety of technical exchange QQ groups, but when you ask questions in the group, you must pay attention to the posture of your questions. First, what problems you encounter, it is best to be able to repeat the failure, and keep the error tips in the form of pictures. Second, what methods you have tried to solve and the process of solving. Third, give a clear account of your environment. In this way, the experts in the group can understand what your problem is and how to do it, which not only saves everyone's time, but also increases the possibility that your problem will be solved. It is really beneficial to others and self-interest!

The fourth secret book of advanced class: persevere

IT is an industry where knowledge is updated rapidly. Various new technologies, frameworks and languages are developing rapidly. Maybe PHP is popular today and Ruby,python will be popular tomorrow, but the technology remains the same and requires us to master the most basic knowledge. With the foundation, even if the technology is updated quickly, we can quickly master emerging technologies. No matter which industry persists, it is a necessary condition for success. If fishing for three days and drying the net for two days, You are sure to accomplish nothing, but if you use the right method and persevere, I believe you will be able to make achievements in your own field!

Finally, I would like to emphasize that beginners do not be too greedy, for example, the linux command has many parameters, options can be matched, but there is no need to remember all the parameters, only the most commonly used basic options can be, but novices often do not have the ability to distinguish these, which requires teachers to work hard to sum up those command parameters are often used. It can be seen how important a reliable textbook is for beginners, not to mention reading the contents of some books, just looking at the thickness of your books scares the beginners. I also read a lot of books during my study. Recently, there is a textbook called "Linux should be learned this way". I think it is more suitable for beginners to learn. The first book is explained by the current Red Hat RHEL7 system, which ensures the advanced nature of knowledge, so as not to say that the technology learned has been eliminated. Second, the book removes some useless complex knowledge, which is too complex for beginners to learn, which will not only hit beginners but also delay the progress of learning. Third, the knowledge is systematic. After reading it, you can have a more systematic understanding of the technology in your operation and maintenance. All right, some of my suggestions for beginners above, I hope there are "secret books" that are suitable for you, which will be helpful to your study!
