In this era of rapid development of the Internet, how can we maintain an iron job? Undoubtedly, the safest thing is to choose a skill that will not be outdated in any era, and choose to study and study in depth. You may think that the topic that Linux should learn in this issue is more mundane. But it has to be said that in the current era, only a certain economic ability can firmly establish a foothold in this society.
What I want to introduce to you next is a skill that has been developed for many years and is becoming more and more popular, which is our pig's feet today - Linux operation and maintenance. And want to get an iron job and even a high salary. The only way is to cultivate the practice of Linux operation and maintenance to the highest level. There is a chance to get a high salary. This issue discusses how to practice Linux operation and maintenance. I recommend a Linux study book " Linux should be learned like this" . It took three years to complete a Linux study book, which is very good.
First, let's take a look at the necessary skills of Linux operation and maintenance engineers:
1. Linux system basics
2. Network Services
3. Shell scripting language
4. Database
5. Firewall
6. Monitoring tools
7. Cluster in hot standby
8. Data backup
9. Text Processing
10. Regular Expressions
Then I will list a few Linux operation and maintenance training heart sutras for you here :
1. Get rid of the traditional Windows system thinking mode in thinking.
It is believed that the first operating system that most people come into contact with when using a computer is still the Windows series of operating systems, and it may have been the Windows operating system that has been used for a long time before the Linux operating system. In this way, it is easy to form the operating habits and thinking habits of the Windows operating system in our minds. Although both Linux and Windows are operating systems, there is not much difference in function. However, the operating habits and way of thinking of Linux are quite different from those of Windows. For example, after I installed "Blue Dot" for the first time, I was puzzled because I couldn't find the D drive. At the same time, most of the newcomers to Linux have a habit: learning Linux is accustomed to operating on a graphical interface, which is probably due to the influence of Windows.
2. Be more hands-on and diligent in practice.
I also often encounter beginners asking me what is a good way to learn Linux well. I basically answer them like this every time: there is no good way, only more hands-on and diligent practice. A very good advantage of learning computers is that you do not need to worry too much about breaking the machine when you test in the test environment or on a virtual machine. Even if the system is broken, it is a big deal to reinstall the system.
A lot of computer knowledge is very abstract. In many cases, if we just read books, we are often confused. Only through continuous practice, testing, and verification can we truly understand a concept.
3. There must be no fear of difficulties and a strong research spirit.
I often see that many newbies will post on the forum when they encounter problems, asking for advice from experts. And many times these people seem to be asking the so-called masters to have a panacea, giving detailed solutions to their problems and even perfect steps. In fact, this is the most important attitude towards the problem. Although the suggestions provided by experts to solve problems may be of great reference value to us, they can only be used as a reference, and we cannot copy their methods without thinking.
4. Good at sorting and summarizing
Knowledge can only be upgraded and serialized through continuous sorting and summarization. Every time we encounter a problem, we can record the scene and solution at that time. As we continue to learn, the knowledge we accumulate will become more and more abundant.
5. Have a strong sense of responsibility and mission.
Basically, operation and maintenance is the last gatekeeper for the system to provide external services. Therefore, whether a system is stable to users has a lot to do with operation and maintenance. In particular, when there is no problem with the system, many operations and maintenance do not pay attention to disaster recovery backup and data security, so once the system fails, it will take a long time to restore the system.
6. Have a continuous learning spirit
The development of computers is really fast, and new knowledge and new technologies emerge one after another. If you don't keep learning continuously, your knowledge will soon age and cannot keep up with the needs of the times.
7. Have the spirit of excellence
It should be said that the flexibility of operation and maintenance work is still very large. That is, you can operate and maintain a system very roughly, and you can continuously improve and optimize the system to make the system run more and more efficiently. And how to make a system run more and more efficiently requires us to have the spirit of excellence and make continuous improvements.
Among these articles, the most important ones are Articles 2 and 4. Be sure to develop the habit of hands-on and summary!
In addition, learn about the necessary skills of the position, and strengthen them in a targeted manner when learning. Go to some recruitment websites, collect job requirements for operation and maintenance engineers, and summarize these job requirements to get a learning route. Studying is the most avoidable anxiety, adjust your mentality, communicate more with your peers, and strive to become a Linux operation and maintenance engineer as soon as possible!
