Why can't a master leave a Linux system? That's my reason.

Why the master can't leave Linux system? That's my reason .

through this article to record I in Linux system learning experience, talk about why I can't leave the Linux system, but also for those who want to try Linux and have some scruples about the user to answer questions, the following will introduce you to my favorite Linux system, here are some you should know and proud of the facts.

you should leave it here first . Windows system, small series also did not say Windows system is bad, just here to talk about some of the advantages of Linux, let you thoroughly understand the characteristics of the Linux system, hope that these can become you love Linux perfect reason.

1. in my eyes. Linux system?

Talk up Linux systems, both unfamiliar and familiar. A few years ago, I have never heard of the word "system", not to mention Linux, it is a face, until the teacher talked about the Linux system, the heart has a little concept, only know that it is able to run the high-level "software" on the computer, real to deep learning, Just understand is a better than Windows operating system, and is open source, perhaps beginners mistakenly think open source is free, wrong! This can be said in turn (free is open source). He is a free and open-source Unix-like operating system that anyone can freely use, completely free of any restrictions, so that 60% of the world's people are using it. Today, no matter where you are, it is impossible to use Linux, according to statistics, more than 2 billion people carry an Android phone every day to go out, his bottom is the Linux system, today's Linux system has been everywhere, contact more, slowly also familiar.

currently Linux is also widely used in embedded systems, such as mobile phones, tablets, routers (Router), TV (TVs), and video games, which are built on the Linux kernel for Android operating systems that are widely available on mobile devices. , as well as a number of Linux distributions for desktop users and server users to choose from.

1. "Investing in the Brain"-learning Linux can be a long process

when we know Linux a series of advantages, there is no reason not to understand him, it is worth our deep learning, need to further explore the Linux world. Do not mind recommending a Linux tutorial reading "Linux should learn this", this is also a good book I recently read, this book can further improve the understanding of Linux systems, expand your horizons.

And It's because of these reasons that I like to Linux system, after reading, I hope you can also like Linux, like Open source.

2. "Hot" multi-user, multi-tasking, multi-threaded

Linux system can support multiple users at the same time, each user to their own file device has a special right to ensure that the user does not interfere with each other, like a mobile phone to open the same as the assistant, while landing multiple QQ account, when the hardware configuration is very high, each user can also perform multiple tasks simultaneously, multiple threads simultaneously work, Improving efficiency is simply a complete mess, but with many users, the rest of the operating system explodes.

3. "Rock solid"-stability and efficiency

you may hear Windows Server has been running for a long time, but you will never hear Linux system servers get stuck for a long time, and this is almost not the case on Linux. Linux servers can run indefinitely without downtime, as he inherits Unix's superior stability and efficiency. It is because of his stability to get the favor of many users, because he is efficient, it is more widely used, but Linux can also provide some high-reliability services, such as: LNMP, virtualization, database services and so on.

4. "Impregnable"-Security and SELinux

its security is much more secure than other systems because Linux has a large number of users and open source community support, so can quickly discover system vulnerabilities, and quickly release security patches timely updates, but also has a strong "immunity" characteristics, very few viruses attack, for an open system, in the user-friendly, there is likely to be a security risk. However, the use of Linux with its own firewall (IPTABLES,FIREWALLD), intrusion detection and security certification tools, timely repair system vulnerabilities, can greatly improve the security of the Linux system, so that hackers can be inorganic, but also the security enhancement mechanism SELinux, The ability to provide mandatory access control in the Linux kernel is comprehensive enough to protect systems and services, but many people like to turn it off, which is not as good as the relative security. There are also tcp_wrappers can provide a good network service access control, Linux system for user and file management Rights Management is also very good, can control permissions, ensure the confidentiality of files, but also other systems can not be compared, So the Linux system is, to some extent, indestructible.

5. "Just so willful"-performance advantages

because Linux to ensure its stability, so there is no other operating system like the kernel is so bloated and bulky, flawed, as the Linux kernel constantly updated, and constantly improve the advantages of the Linux operating system to the server's hardware advantages reflect the incisively and vividly, Because the Linux system absorbs the experience of UNIX system development for nearly 1/4 century, the most important is the Linux open source code, ensure system stability, better call the hardware function, and also provide rich system resource tool TOP,FREEE,DF,VMSTAT,DMESG, Iostat,sar,uptime and so on, convenient to view the utilization of resources, Linux command Daquan, can own Baidu "Linux should Learn" the second chapter.

6. "Nobody is perfect"-I admit he has flaws.

despite It's undeniable that there will be a shortage of good Linux. People think that the graphical interface is not friendly, I do not think so, because the graphical interface is seldom used. However, at present, the major Linux distributions have improved a lot on the desktop, such as RHEL7 after the desktop has been a great improvement.

Why can't a master leave a Linux system? That's my reason.
