This article is to share with you about the version of Red Hat, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

Linux is already familiar with, Linux is a mature and stable network operating system, for those who learn Linux users, you must know Red Hat, this article introduces several versions of Red Hat for you, hope that beginners can learn to choose Linux system.

1.Red Hat Linux

Red Hat Linux is the earliest personal version of Linux released by redhat, its 1. Version 0 was released on November 3, 1994. Although it is not as old as other Linux distributions, Red Hat has a much longer history than many Linux distributions. Since Red Hat 9. After the release of version 0, RedHat no longer developed the desktop version of the Linux distribution, and RedHat Linux stopped development and focused all its efforts on the development of the server version, that is, the RedHat Enterprise Linux version. On April 30, 2004, Red Hat officially stopped its response to Red Hat 9. The support of version 0 marks the official end of Red Hat Linux. The original desktop Red Hat Linux distribution is merged with the Fedora project from the open source community to form the Fedora Core distribution.

Red Hat is currently divided into two series: Red Hat Enterprise Linux, which is supported and updated by Red Hat for a fee, and Fedora Core, which is free of charge developed by the community.

2.Fedora Core

Fedora Core (abbreviated as FC) is positioned by Red Hat as an experimental site for new technologies, many new technologies will be tested in FC, and Red Hat will consider joining Red Hat Enterprise Linux if it is stable. Fedora Core 1 was released in late 2003, and FC is targeted at desktop users. FC provides * software packages, and its version update cycle is very short, only 6 months. Due to frequent version updates, performance and stability are not guaranteed, so Fedora Core is generally not recommended on the server. In fact, you can think of Fedora as an experimental version of Red Hat Enterprise Edition Linux released by Red Hat, testing users as the basis for the release of Red Hat Enterprise Edition.

3.Red Hat Enterprise Linux

Red Hat Enterprise Linux (Enterprise Edition abbreviated RHEL,Red Hat). Red Hat is now mainly doing Linux development for the server version, focusing on performance and stability as well as hardware support in the version. Due to the long development cycle of the enterprise operating system, focusing on performance, stability and server-side software support, the version update is relatively slow.

RedHat Enterprise Linux is divided into four versions: Advanced Server (AS), ES Workstation (WS) and Desktop. There is not much difference between them, only in terms of function.

4.Centos

CentOS's full name is Community Enterprise operating system (Community Enterprise Operating System)

The background of CentOS:

Redhat releases Redhat 9. After 0. 0, no longer develop redhat 10J 11. The new redhat Enterprise Edition requires users to buy lisence,redhat first and make a commitment to ensure the stability and security of the product. The rhel binaries are no longer available for download but as part of the redhat service, but the source code is still open. In this case, there are a number of enterprise versions of open source, such as centos, whitebox, dao, and so on, of which centos is the most active.

Here's how centos is made:

The CentOS community downloads all the source code on Red hat's website and recompiles it. Because AS/ES/WS is a commercial product, you must change the Logo and logo of all Red hat to your own CentOS logo. For example, AS4. The original SRPM source code of 0. 0 is compiled and replaced with logo of the Centos community, which becomes CentOS 4. 0 . When the source code of Redhat Enterprise Linux AS4 Update1 is compiled, it becomes CentOS4. one. When the source code of AS4 Update2 is compiled, it becomes CentOS4. 2, wait. This is how CentOS comes into being.

Therefore, it can be said that CentOS is the free version of Redhat's AS/ES/WS, and you can get the same functionality and performance as red hat enterprise Linux using centos. At the same time, centos also provides free long-term upgrade and update services. Therefore, among the many cloned versions of RHEL, CentOS is very outstanding.

Although centos is a clone of RHEL, it is not exactly the same, and the clone is 100% interchangeable. It's not the same for centos. RHEL's software doesn't work 100% on CentOS.

These are the versions of Red Hat, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
