Linux System Introduction

Linux overview of

  • Linux is an operating system, free, open source, secure, efficient, stable, and powerful enough to handle high concurrency. Many enterprise projects are deployed to Linux/ Unix servers

    Linux is free and open source, while Unix is not

    Linux can run on a variety of hardware platforms (more compatible), while Unix systems need to be compatible with the corresponding hardware (less compatible)

  • Linux founder: Linux Linus

The advantage of Linux

  1. The shortcomings of Windows

    • Windows costs money

    1. Over time, with more software installed, the system becomes slower and more unstable.

    2. There are many viruses and malware

  2. Advantages of the Linux system

    • Linux is free, and many are open source.

    1. Long running, very stable, almost become the best system environment for program code to run.

    2. Almost no virus and rogue software

To compare Windows Linux
Free and Charged It’s expensive and it’s expensive Linux is free or at a small cost
Software and Support Quantity and quality advantages, however, most of them are paid soft open source free software, users can modify customization and re-release, mail; Officially supported and serviced by Microsoft. Open source free software, users can modify customization and re-release, because the basic free without financial support, some software quality and experience lack; Supported by all Linux developers and the free software community around the world.
security Every three days to patch the installation of system security updates, or in the Trojan virus. Very vexed. It’s impossible to say that Linux doesn’t have a security problem and it’s a matter of opinion, but it’s certainly more secure than Windows.
Use habits Ordinary users are basically pure graphical interface operation, relying on the mouse and keyboard to complete all operations, users get started easily simple. Both graphical interface operation and complete command line operation, can only use the keyboard to complete all operations, beginners are difficult to get started, need some learning and guidance, once skilled efficiency is extremely high.
customizability Closed, poorly customizable system open source, poorly customizable. Open source, very customizable.
Application scenarios The predominant desktop operating system is still Windows. Supporting baidu, Taobao and other applications and services, is the background of thousands of Linux server host. Most of the world’s software and services run on Linux.

The classification of the Linux

  • According to the different needs of the market, it is divided into graphical interface and character interface operating system

    1. The graphical interface

       

      For mobile phones, Android is Linux

    2. Character interface (recommended). Features: Optimal performance

     

  • According to the degree of primitive

    The kernel version, developed by the Father of Linux (Torvaz) team, is completely free

    Features: The kernel version is a system platform designed to operate hardware

    A distribution is a version of a kernel that is wrapped around a kernel version by a third party

    Features: there are a lot of very useful applications, more efficient use of the system

Common distributions of Linux systems

  • Note the following common releases:
system introduce
ubuntu It is an open source Linux system mainly based on graphical interface desktop applications. In 2014, it married with domestic Meizu to become a smartphone operating system
redhat There are community open source edition and Enterprise Server edition. Enterprise Server edition is available for a fee
centos It is decompiled from redhat enterprise edition, which has the same performance as redhat enterprise edition and is completely free. But if there is a problem, you can go to the official feedback, the official may be in the next version to solve the problem.

  • Relationship between Linux and Uinx

The Linux installation

We can refer directly to the Linux installation I sent earlier.

conclusion

I believe you have a certain understanding of some of the concepts of Linux system introduction, looking forward to waiting for the next chapter of Linux commands!

Of course, there are more commands waiting for you next time! Welcome to the next chapter!
