The advantages of Linux system and what suggestions, many novices are not very clear about this, in order to help you solve this problem, the following small series will explain in detail for everyone, there are people who need this to learn, I hope you can gain something.

Linux system makes us understand that sharing, openness and freedom can make human life better. The spirit of open source is a feeling that makes every technician engaged in Linux industry proud from the bones. The prosperity of open source products benefits from the strong foundation of open source community. Linux has really given me a lot, not only the beauty of technology, but also the beauty of life. Next I want to talk more about Linux, let me lift the veil of the Linux system for you, and I hope to resonate with you!

The Linux operating system was originally released in October 1991 by Linus Torvalds, a student at the University of Helsinki in Finland. It's him, it's him, it's him, Linus Torvalds, the father of Linux! I have read a lot of Linux books, in the part of thanks, must first thank linus Torvalds, after all, married a daughter also have to thank the father-in-law, right? Linux 0.02 was originally released because of its high quality and open source code, quickly attracted a large number of hackers "onlookers", although there are hundreds of Linux distributions, but still uniformly use Linus Torvalds development/maintenance system kernel, although the times have changed, but left a really precious thing--Linux kernel.

Let's look at the good things about Linux, and I'm sure you'll feel it when you learn or use it, and you'll all say,"Linux is so easy to use."

Linux has the following advantages over Windows:

Stable and efficient

Free or at a small cost

Fewer vulnerabilities and quick fixes

Multitasking, multi-user

More secure user and file permission policies

Embedded Systems for Small Kernels

Relatively inexpensive.

See, these are the excellent features of Linux, can be said to be "beautiful and lively" beautiful girl,"noble and cool" beautiful lady! Know the advantages, then let's see what Linux beginners should pay attention to, the following content only hope to give Linux beginners a little help. These are Linux beginners need to pay attention to the place, we learn the process is often a chore, so in the process of learning to find and you will be the same people or things is a very happy thing, not only because of the content of this book, but also because of the exchange environment provided by this book, there are too many Linux enthusiasts here to learn, grow here, find like-minded friends here.

Tap commands and use tab keys to complete, copy as much as possible when writing scripts

When using Linux for a period of time, I believe that you will become more and more proficient in various commands, this time people are easy to believe themselves, it is easy to lead to errors, if we are almost finished, subconsciously use the tab key, then we can easily avoid errors. In shell scripts, however, our commands should be copied from the test command line as much as possible, so as to avoid the risk of typing errors due to lengthy commands.

Complete the operation with normal users, and use root as little as possible.

The root super account has the same power as the emperor.

The greater the power, the more dangerous and need to pay attention to the place, which requires not only the user has good Linux skills, but also a certain amount of experience, so for beginners, or as little as possible to use root user it. When some of our operations require root privileges, we can modify the sudoers file to allow ordinary users to perform operations with root privileges, so that we can complete the operation and ensure the safety of the operation.

Remember to backup when modifying configuration files

Linux configuration files often correspond to service or system configurations, so we must ensure that the configuration files are correct. So before we do anything, we must consider whether it is reversible (after the operation, whether it can be restored to the way it was before the operation). So backup before modification, so that the operation has reversible properties, even if the configuration file deleted, there are backup files for us to do protection.

Notice the principle of least.

Minimize the installation package: only install the basic package of the system, do not blindly seek to be large and install a lot of useless packages, this time our system burden will also become larger, consuming more hardware resources. If there is a need for other packages or services later, we can install them through tools such as yum.

Minimization of permissions: any user should try to give ordinary user permissions, ensure that the user's permission requirements, when necessary, and then expand, system files and directory permissions also need to be controlled, pay attention to different files for different permissions of users, so that files can be more secure.
