This article mainly shows you "which versions of Linux", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "which versions of Linux" this article.

I. Redhat series

At present, many experts use it, general appearance but very strong, generally Linux master * * system, by contrast, the desktop system is a little different, with a powerful rpm software package management system, the interface is more concise, if you do not like too many fancy desktop systems can consider using it! Redhat series, including RHEL (Redhat Enterprise Linux, also known as RedhatAdvance Server, paid version), FedoraCore (developed from the original Redhat desktop version, free version), CentOS (community clone of RHEL, free).

Redhat should be said to be the most popular version of Linux in China. Some people even equate Redhat with Linux, and some old birds only use this version of Linux. So this version is characterized by a large number of users, a lot of information, the implication is that if you do not understand anything, it is easy to find people to ask, and the general online Linux tutorials take Redhat as an example to explain. The package management mode of Redhat series adopts the YUM package management mode based on RPM package, and the package distribution mode is compiled binary files. In terms of stability, RHEL and CentOS are very stable and suitable for server use, but the stability of Fedora Core is poor, and it is only used for desktop applications.

II. Debian series

Debian series, including Debian and Ubuntu, etc. Debian is a model of community-based Linux, and it is by far the most GNU-compliant Linux system. Debian was first founded by Ian Murdock in 1993 and is divided into three version branches (branch): stable, testing and unstable. Unstable is a test version of * *, which includes * software packages, but there are also relatively many bug, which are suitable for desktop users. Testing versions have been tested in unstable, are relatively stable, and support a number of new technologies (such as SMP, etc.). While stable is generally only used for servers, most of the above software packages are outdated, but the stability and security are very high. Debian*** is characterized by apt-get / dpkg package management. In fact, Redhat's YUM is also imitating Debian's APT mode, but in binary file distribution, APT should be * *. Debian is also rich in information, there are many supportive communities, and there are places to go if you have questions to ask for advice.

III. Gentoo

Gentoo, the great Gentoo is the youngest distribution in the world of Linux, and because she is young, she can draw on the advantages of all her previous distributions, which is one of the reasons why Gentoo is called the most * Linux distribution. Gentoo was originally created by Daniel Robbins, one of the developers of FreeBSD, and the stable version was released in 2002. Because developers are familiar with FreeBSD, Gentoo has a widely acclaimed ports system comparable to FreeBSD-Portage package management system. Unlike the package management system for binary file distribution such as APT and YUM, Portage is distributed based on source code and must be compiled before it can be run, which is slow for large software, but it is precisely because all software is compiled on the local machine, after various customized compilation parameters optimization, the hardware performance of the machine can be brought into full play. Gentoo is the most complex installation of all Linux distributions, but it is the most manageable version after installation, and it is also the fastest version running in the same hardware environment.

IV. FreeBSD

It needs to be emphasized that FreeBSD is not a Linux system! However, a considerable part of the user base of FreeBSD and Linux coincides, the hardware environment they support is the same, and the software used is similar, so FreeBSD can be compared as a Linux version. FreeBSD has two branches: stable and current. As the name implies, stable is a stable version, while current is a beta version with new technologies added. FreeBSD uses a Ports package management system, similar to Gentoo, which is based on source code distribution and must be compiled on the local machine before it can be run, but the Ports system is not as easy to use as the Portage system and is slightly more complicated to use. FreeBSD is characterized by stability and efficiency, which is the choice of server operating system, but its hardware support is not as complete as Linux, so it is not suitable for desktop system.

5. OpenSUSE

OpenSUSE: a very popular Linux in Europe, issued by Novell, which claims to be the most gorgeous operating system in the world. The exclusively developed software management program zypper | | yast has been praised by many users. Like ubuntu, it supports desktops such as kde and gnome,xface. Desktop effects are rich, but the disadvantage is that KDE is gorgeous and colorful, but it is relatively unstable. This is also easy for beginners to use.
