The connections and differences between Linux distributions

There are three main branches of Linux distributions: Debian, Slackware, RedHat.
(1) Debian: (works in a community way)
1,. Ubuntu: Open source Linux operating system based on Debian, mainly for desktop and server;
2. Linux Mint: Linux distributions based on Debian and Ubuntu are dedicated to making desktop systems easier and more efficient for individual users on a daily basis, with the goal of providing a more complete, instantly available experience.

(2) Slackware:
1, SuSE: Based on the development of a Slackware two Linux, mainly for commercial desktops, servers.
2. SLEs (SUSE Linux Enterprise Server (SLES): Corporate servers operating system, is the only Linux operating system that can be compatible with the Microsoft operating system.
3. OpenSUSE: Developed by SUSE, designed to promote the widespread use of Linux, mainly used in desktop environments, the user interface is very gorgeous, and performance is good.

(3) Redhat
1. Rhel (Red Hat Enterprise Linux): Red Hat releases the Linux operating system for enterprise users. Early version is mainly used for desktop environment, free; since April 30, 2004, Red Hat officially stopped supporting Red Hat 9.0, marking the end of the free time for Red Hat Linux. Since then, Red Hat is no longer developing a desktop version of the Linux distribution package, and will concentrate all its power on the development of the server edition, Red Hat Enterprise Linux. Release a new version every 18 months, the kernel is relatively low, strive to be stable, do not seek the latest.

2. Fedora: Based on Red Hat Linux, Red Hat Linux is planning to replace Red Hat Linux in the personal domain with Fedora, and the other Red Hat Enterprise Linux replaces red when it terminates its release. Hat Linux in the field of commercial applications. Fedora's functionality is a full-featured, fast-updating, free operating system for the user, and for the patron Red Hat It is a testing platform for many new technologies, and the technologies that are thought to be available will eventually be added to Red Hat Enterprise Linux. Fedora releases new releases approximately every six months.

3. CentOS: An enterprise-class Linux distribution based on Red Hat Linux that provides free access to source code. Each version of CentOS receives a ten-year support (via security update). The new version of CentOS is released about once every two years, and each version of CentOS is updated periodically (approximately every six months) to support new hardware. This creates a secure, low-maintenance, stable, highly predictive, high-repeatability Linux environment. CentOS is the product of the source code recompilation of Rhel (Red Hat Enterprise Linux), and it fixes a number of known bugs on the basis of Rhel, and is reliable with respect to other Linux distributions. CentOS was announced to join Red Hat at the beginning of 2014. CentOS added to Red Hat unchanged is 1. CentOS continues to be free of charge; 2. Keep the sponsored content-driven network center intact; 3. The Bug, Issue, and emergency handling strategies are unchanged; 4. Red Hat Enterprise Linux and the CentOS firewall are still there; the change is: 1. We are working for Red Hat, not for rhel;2. Red Hat provides sponsorship of the build system and initial content distribution resources; 3. Some development resources including source access will be easier; 4. avoided the original and red Hat some of the legal issues.

(4) Other releases:
Gentoo: Linux-based free operating system that automatically optimizes and customizes almost any application or requirement. The quest for extreme configuration, performance, and top-notch user and developer communities are hallmarks of the Gentoo experience, and Gentoo's philosophy is freedom and choice. Thanks to a technology called Portage, Gentoo can be an ideal secure server, development workstation, professional desktop, gaming system, embedded solution, or something else-what you want it to be. Because of its near-limitless adaptability, Gentoo is known as the meta-distribution.

Arch Linux (or arch): a Linux distribution with lightweight simplicity as its design concept. Its development team is designed with simplicity, elegance, correctness and minimal code.

Contact: All distributions use the Linux kernel; all distributions have their own version number, and the version format Convention is basically the same (major version number. minor version number. Issue number or revision number).

Difference: The essential difference between distributions is the combination of different versions of the kernel, libraries, and programs. Different distributions have almost adopted different package managers (SLES, Fedora, OpenSUSE, CentOS, Rhel use RMP package management system, package files with rpm extension, Ubuntu series, Debian series using DPKG package management system, The package file is extended with the Deb extension. ）
