This article mainly explains the "detailed use of CentOS", the content of the explanation is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in depth, together to study and learn "the detailed use of CentOS" bar!

CentOS is already familiar to everyone. What is CentOS? CentOS (Community ENTerprise Operating System) is one of the Linux distributions, which is compiled from the source code released by Red Hat Enterprise Linux in accordance with open source regulations. Because it comes from the same source code, some servers that require high stability replace the commercial version of Red Hat Enterprise Linux with CentOS. The following describes the use of CentOS.

Since the official release of redhat 9 by redhat (abbreviated as rh9), we will no longer continue to develop redhat 10Magi 11. A comprehensive shift to the development of RedHat Enterprise Linux (RHEL), unlike in the past, the new RHEL 3 requires users to buy lisence,redhat.com first and promises to ensure the stability and security of the product. The rhel 3 binaries are no longer available for download but are part of the redhat service, but the source code is still open source. That's why 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 distribution.

The full name of the ── launched by the CentOS program is the Community Enterprise operating system (Community Enterprise Operating System), which is one of some of the "Red Hat rebuilders" (Red Hat rebuilders) after Red Hat decided not to provide free technical support and product certification in 2003.

CentOS and Linueox, Assembly Linux (White box Linux), Tao Linux, X/OS Linux, and Scientific Linux (Scientific Linux) all reconstruct the Red Hat Enterprise Linux copy with the original source code released by Red Hat.

CentOS is an offshoot of the "Caos Linux" independent program, said Kurtzer, an administrator and programmer at Lawrence Berkeley National Lab. But then the Caos Foundation's plan became the reconstruction of RHEL.

"for the new version that is widely adopted, it is necessary to show the community a stable and reliable solution for its plans and products." Kurtzer said. "but because CentOS is based on a well-known source code platform, it can take shortcuts and succeed overnight."

Kurtzer doesn't have exact figures, but he estimates that there are thousands of CentOS users.

The CentOS community downloads all the source code on Redhat's website and recompiles it. After recompilation, since AS/ES/WS is a commercial product, you must change the Logo and logo of all Redhat to your own CentOS logo. For example, after compiling the original SRPM source code of AS4, it becomes CentOS 4.0. When the source code of AS4Update1 is compiled, it becomes CentOS4.1. When the source code of AS4Update2 is compiled, it becomes CentOS4.2. Similarly, the 3.x/4.x of CentOS corresponds to the corresponding version.

So we say that CentOS is the free version of Redhat's AS/ES/WS. With CentOS, you can get the same performance and feel as AS/ES. In addition to several standard ISO numbered 1-4 or 1-5, CentOS also provides Server discs that minimize 1CD. A system installed with a Server CD is a minimized Linux kernel plus a commonly used httpd/mysql package, excluding software such as Xwindows desktops that are useless to the server.

Thank you for your reading, the above is the content of "detailed use of CentOS", after the study of this article, I believe you have a deeper understanding of the detailed use of CentOS, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
