In June 2015, an accidental opportunity made me, a non-scientific-born person, engaged in the operation and maintenance industry. In the past two years, from a broad perspective, the operation and maintenance community and technical salons have continued to rise, and various media seem to suddenly pay attention to the operation and maintenance industry. The former scapegoat suddenly received attention from all quarters. Since I was a child, I didn't even know IP from the very beginning. I learned a little bit and made a little progress. When I look back at the year, I know so much. Writing this article, I just want to share the ups and downs of the past two years, and give some hope to the little whites who also have no foundation, and take less of the wrong road of their predecessors.
At this time two years ago, it was the recruiting season for fresh graduates, and my parents wanted me to work in a stable industry, such as teaching, civil servants, banking, etc. However, when I was young, for the first time, I turned the idea of being the master of my life into practical actions, and resolutely voted for many positions in the IT industry. Even at that time, I didn't even know what IP and gateway were. Maybe it's a matter of luck. A company is short of people, and it just needs to recruit some careful support engineers. I am very lucky to enter the industry of linux system operation and maintenance. On the first day of employment, take part in the induction training with a curious and excited heart. However, the content, business process and zhuan of the first day. Professional knowledge makes me feel frustrated. I don't know what ssh is, I don't know what putty is, I don't know what mount is, and I don't know what virtualip is. For the first time in my life, I have doubts about my IQ. After I went back, I cried a lot, and told myself that I would definitely learn linux well and not hold back the team. At that time, I didn't know the book "Linux should be learned like this". I thought that if I knew it, I might be able to spend a lot less time and take a lot of detours. Of course, this is another story. Let me tell you about my work first. .
The company has a lot of technical documents. As a support engineer, my responsibility is to be able to operate the incident and service request work orders according to the document operation standards. This may be quite boring for a technical expert, but to me it is like reading a book from heaven. I don't know what each command means when I type it, and I don't know what the correct result is. During those three or four months, I read these documents over and over on wan every day, trying to understand the meaning of each step of his operation, and went online to check the functions of these commands, and I also took the initiative to propose this chore that others think of managing the company's documents. With a little accumulation, you will gradually be able to handle the problems proficiently. However, I always feel that I have not learned the essence of linux, and I have not learned enough. If I switch to another company and change the operation and maintenance framework, I ask myself, can I do it?
With such a tangled mind, I went to the Internet to search for relevant linux training courses, check the basic books of zhaolinux, hope to have a comprehensive and systematic understanding of linux, and hope that the road to learning linux can get a little light. However, the training courses are diverse, and the books are dazzling, which makes me dazzled, and the software inside does not know where to go, which is really difficult for a novice like me. Later, by chance, I saw someone in the operation and maintenance group recommend the book "Linux should be learned like this", so I searched it with the mentality of trying it out, and found that it was really interesting. There is also a website called linuxprobe It can be read online, and the supporting software in the book can be downloaded directly above! This is simply Xiaobai's savior! Most importantly, learn and listen to music! This is what I never thought, boring Linux can still learn like this. And every chapter is very clear. Check out the catalogue below!
This website was immediately pulled into my favorites and regarded as a treasure. According to the experiment in the book, I typed the command step by step, and did the experiment little by little. The previously ambiguous knowledge suddenly became clear, and I gradually gained a general understanding of the functions and configurations of various services. Later, I went to participate in the training of the author of this book. After the training, I finally gained confidence in being competent for Linux operation and maintenance work.
Since then, with a solid foundation, the work has been smoother. Later, just as the DevOps department on the Chinese side of the company was just established, the boss asked me to change the department. Of course, as DevOps, you have to learn a lot of other new knowledge, such as programming and so on. Now, I haven't found an excellent book that can give me a quick and systematic understanding of DevOps, and I can only move forward slowly again like a blind man. However, I believe that operation and maintenance development is the development trend of traditional operation and maintenance. The amount of data is increasing, and the pressure on traditional operation and maintenance is also increasing. We urgently need an operation and maintenance solution to systematically manage operation and maintenance. dimension. Public cloud and private cloud are springing up like mushrooms, heralding a boom in the industry. No matter how many black pots the previous operation and maintenance operators have for development, they must always believe in their own value. After all, I have always believed that operations and development are one.
