What types of linux are there?

Common Linux systems include Ubuntu, Fedora, Debian, Redhat Enterprise, Linux SUSE OpenSUSE, Mindriva, Gentoo, Arch, Slackware, etc.                                                                                                                                                                                                                   (Recommended learning: linux tutorial )

These mainstream distributions account for almost all of them, and basically all of them are free to use and install, except for a few exceptions Paid version

Such as linspire, almost all distributions including RHEL can obtain the installation CD image for free on the official website.

Debian is generally used by private servers in non-commercial and non-governmental sectors. Outside companies generally use redhat enterprise version, namely RHEL (Redhat Enterprise Linux) and CentOS.

CentOS comes from Red Hat Enterprise

Linux is compiled from source code released in accordance with open source regulations. Since it comes from the same source code, some servers that require high stability use CentOS instead of the commercial version of Red

Hat Enterprise

Linux. The difference between the two is that CentOS does not contain closed source software.

1. redhat

is, after all, a mainstream server-level Linux version. The most important thing is to provide various professional technical support and provide large technical and product solutions. It has the only global Linux professional and technical certification body. Red Hat is the first choice for large servers in many state-owned enterprises and large and medium-sized enterprises.

2. Centos

is actually just a brand change of redhat. There is basically no difference compared to redhat. The advantage is that it is completely free. The disadvantage is that it does not provide any technical support. . Some standard server systems are often used by small and medium-sized enterprises.

3, ubuntu

Personal system is very good, especially the design of rich resource library and leading graphical interface. However, it is still not used too much as a server.

The major Internet companies still use Centos, fedora, and redhat. If large enterprises use them as data centers, it is estimated that ubuntuserver’s share is not yet available. Ubuntu server needs to prove itself to these enterprises and wait for these enterprises. Evaluate.

Currently, redhat and suse account for 90% of enterprise data center servers. Suse has been declining, and redhat is the leader.

centOS does not have the unique advantages of redhat, and even its latecomer potential is not as good as SL. Redhat's services are relatively good, its products are relatively stable, and those big companies are willing to spend money to get services. Radhat basically takes most of the money earned by servers under Linux.

Ubuntu server has a strong upward momentum. I hope to take 12.04lts as an opportunity to achieve great development.
