Linux was first written by Linus Benedict Torvalds in 1991. Before that, Richard Stallman founded the Free Software Foundation (FSF) organization and the GNU project, and continued to write and create GNU programs (the licenses for such programs are GPL: General Public License). The Linux we see today, or GNU/Linux, was created after the continuous addition of outstanding programmers and developers to the GNU organization.
Linux distributions can be roughly divided into two categories, one is the distribution maintained by commercial companies, the other is the distribution maintained by community organizations, the former is represented by the famous Redhat (RHEL), and the latter is represented by Debian
Redhat, which should be called the Redhat series, includes RHEL (Redhat Enterprise Linux, also known as Redhat Advance Server, paid version), Fedora Core (developed from the original Redhat desktop version, free version), CentOS (community clone of RHEL) version, free)
Red Hat Linux is the earliest personal version of Linux released by redhat, and its 1.0 version was released on November 3, 1994. Although it is not as old as other Linux distributions, Red Hat is much older than many Linux distributions. Since the release of Red Hat 9.0, Red Hat has stopped developing desktop Linux distributions, and Red Hat Linux has stopped developing, and concentrated on the development of the server version, which is Red Hat Enterprise Linux. On April 30, 2004, Red Hat officially stopped supporting the Red Hat 9.0 version, marking the official end of Red Hat Linux. The original desktop Red Hat Linux distribution was merged with the Fedora project from the open source community to become the Fedora Core distribution
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. If it is stable, Red Hat will consider joining Red Hat Enterprise Linux.
Red Hat Enterprise Linux
Red Hat Enterprise Linux (abbreviated as RHEL, the enterprise version of Red Hat). Red Hat is now mainly engaged in the development of the server version of Linux, focusing on performance and stability as well as hardware support in the version. Due to the long development cycle of the enterprise version of the operating system, focusing on performance, stability and server-side software support, version updates are relatively slow.
CentOS is a free, open source, redistributed open source operating system. CentOS (Community Enterprise Operating System, which means community enterprise operating system in Chinese) is one of the Linux distributions.
Ubuntu is a derivative of Debian and the most popular free operating system today. It is a Linux operating system based on desktop applications. An operating system built from free software. Ubuntu has a huge community strength, and users can easily get help from the community. On January 3, 2013, Ubuntu officially released a mobile operating system for smartphones.
The most popular LINUX in continental Europe originated in Germany and was acquired by Novell in late 2003. The main versions are: SUSE Linux, which can be downloaded for free for individual users; Another is that SUSE Linux Enterprise Server (SLES) is based on the enterprise server side. If you need to use advanced database services and e-mail network applications, you can choose SUSE
It is the youngest distribution in the Linux world. Because of its youth, it can absorb the advantages of all distributions before her. Gentoo was originally created by Daniel Robbins (one of the developers of FreeBSD), and the first stable version was released in 2002. Due to the developer's familiarity with FreeBSD, Gentoo has a widely-reputed ports system comparable to FreeBSD, the Portage package management system. Unlike package management systems such as APT and YUM that distribute binary files, Portage is distributed based on source code and must be compiled to run, which is slow for large-scale software, but because all software is compiled on the local machine, in After various customized compilation parameters are optimized, the hardware performance of the machine can be maximized. Gentoo is the most complicated to install among all Linux distributions, but it is also the most manageable version after installation, and it is also the fastest version under the same hardware environment.
