RHEL is the abbreviation of Red Hat Enterprise Linux and is the Linux system of Red Hat
2Centos
CentOS (Community Enterprise Operating System Chinese means: Community Enterprise Operating System) is Linux
One of the distributions, it is compiled from the source code released by Red Hat Enterprise Linux in accordance with the 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 include closed source software.
3ubuntu
Ubuntu (Youbangtuo, Youbantu, Ubantu)
It is an open source GNU/Linux operating system based on desktop applications. Ubuntu is based on Debian GNU/Linux, supports x86, amd64 (ie x64) and ppc architecture, and is created by a global professional development team (Canonical Ltd)
4Debian
In a broad sense, Debian refers to a cooperative organization dedicated to the creation of a free operating system and its works. Because the many kernel branches of the Debian project are mainly based on the Linux macro kernel, and most of the basic tools in the operating system created by Debian developers come from The GNU Project, so "Debian" often refers to Debian GNU/Linux.
