How to choose a Linux distribution

In fact, most enterprises use RHEL or CentOS as the server operating system, and both RHEL and CentOS are RED

A product of the HAT company, where CentOS can also be considered a clone version of Rhel, for Linux beginners, the only difference between Rhel and CentOS is:

CentOS is recompiled using the free RHEL source**, which is freely available to users, and its essence is not much different from RHEL.

1. Most domestic enterprises use RHEL to build servers, and more and more enterprises are using CentOS;

2. CentOS and RHEL are almost the same, and CentOS has free yum tools to use;

3. CentOS is now a member of Red Hat, and it is still completely free;

4. The essence of learning Linux is to learn its core mechanisms, and CentOS has not changed these mechanisms;

All in all, if you are really interested in Linux and want to learn it all the time, CentOS is a very good choice, and you can experience the server system environment of a large Internet company while using it for free, which is also very beneficial for future interviews and job searches.

Is it possible to swap kernels for different Linux distributions? Why can the same docker image run indiscriminately across distributions? Why is there no docker image for Windows under Linux?

I'm going to try to explain it to you in a layman's way....

Linux distributions use the same Linux kernel, so there are no compatibility issues at the kernel level, and each version has a different feel, only in the outermost layer of the distribution (the application that the distributor integrates and develops).

Linux distributions can be broadly divided into two categories:

distributions maintained by commercial companies, represented by the famous Red Hat;

Distros maintained by community organizations, represented by Debian.

It's hard to say which one is better out of a large number of Linux versions, each with its own characteristics. Here are a few popular Linux distributions.

1) red hat linux

2) ubuntu linux

Linux distros with Windows or Mac

OS, Linux is made up of several types called distributions, and each distro seems to be similar, but not quite the same. In general, a Linux distribution is a collection of applications that are adapted to the purpose of use, and in addition to being installed on a server, they need to be set up in advance so that they can be used immediately.

Linux distribution recommended

To put it simply, a Linux distribution is a package of the Linux kernel and application software and distributed to users. In the popularization of Linux, the distributions play a big role.
