What are the linux systems?
Linux operating system was born on October 5, 1991
but there are many versions. It is currently used by people all over the world. Because it is open source, engineers around the world are constantly contributing code to the Linux operating system to make it more perfect.
Linux operating system is widely used in tablets, switches, routers, video game consoles, desktop computers, handheld games, mainframes and supercomputers. (Recommended learning: linux operation and maintenance)
It should be emphasized that Linux itself is just a kernel, without a graphical interface and various gadgets that can dazzle you.
Therefore, we call those systems developed on the basis of the Linux kernel as Linux distributions.
Debian
Debian is extremely stable, which makes it ideal for use on servers. Debian usually maintains three sets of formal software libraries and one set of non-free software libraries, which has inspired several other distributions (such as Ubuntu and Kali, etc.).
The Debian operating system has derived multiple Linux distributions. It has over 37,500 packages, and the only other distribution that outdoes Debian in this regard is Gentoo. Debian uses apt or aptitude to install and update software.
Gentoo
Like Debian, the Gentoo operating system also contains a large number of software packages. Gentoo does not come in a precompiled form, but needs to be compiled for each system each time. Even the Gentoo community finds Gentoo difficult to install and use; however, it is considered the best place to learn about the inner workings of the Linux operating system.
When it comes to Gentoo, someone always says: "If you want to learn to use a Linux distribution, then learn to use that distribution; if you learn Gentoo, you also learn Linux." Gentoo uses portage to install and updated software.
Ubuntu
Ubuntu is a derivative of Debian and the most popular free operating system today. Ubuntu focuses on its applications in this market and is common on servers, cloud computing, and even some mobile devices running Ubuntu Linux.
Red Hat Enterprise Linux
This is the first Linux distribution for the commercial market. It is available in server versions and supports numerous processor architectures, including x86 and x86_64. Red Hat trains and certifies system administrators through the course Red Hat Certified System Administrator/Red Hat Certified Engineer (RHCSA/RHCE). As far as the global market is concerned, 80% of the total profit comes from support and the other 20% comes from training and certification, but this is not the case in India.
CentOS
CentOS is an enterprise Linux distribution built from the ground up using free source code from Red Hat Enterprise Linux. This refactored version completely removes the registered trademark and a very subtle change in the Binary package.

Difference between centos and ubuntu
Apr 14, 2025 pm 09:09 PM
The key differences between CentOS and Ubuntu are: origin (CentOS originates from Red Hat, for enterprises; Ubuntu originates from Debian, for individuals), package management (CentOS uses yum, focusing on stability; Ubuntu uses apt, for high update frequency), support cycle (CentOS provides 10 years of support, Ubuntu provides 5 years of LTS support), community support (CentOS focuses on stability, Ubuntu provides a wide range of tutorials and documents), uses (CentOS is biased towards servers, Ubuntu is suitable for servers and desktops), other differences include installation simplicity (CentOS is thin)
What to do if the docker image fails
Apr 15, 2025 am 11:21 AM
Troubleshooting steps for failed Docker image build: Check Dockerfile syntax and dependency version. Check if the build context contains the required source code and dependencies. View the build log for error details. Use the --target option to build a hierarchical phase to identify failure points. Make sure to use the latest version of Docker engine. Build the image with --t [image-name]:debug mode to debug the problem. Check disk space and make sure it is sufficient. Disable SELinux to prevent interference with the build process. Ask community platforms for help, provide Dockerfiles and build log descriptions for more specific suggestions.
How to view the docker process

Detailed explanation of docker principle
Apr 14, 2025 pm 11:57 PM
Docker uses Linux kernel features to provide an efficient and isolated application running environment. Its working principle is as follows: 1. The mirror is used as a read-only template, which contains everything you need to run the application; 2. The Union File System (UnionFS) stacks multiple file systems, only storing the differences, saving space and speeding up; 3. The daemon manages the mirrors and containers, and the client uses them for interaction; 4. Namespaces and cgroups implement container isolation and resource limitations; 5. Multiple network modes support container interconnection. Only by understanding these core concepts can you better utilize Docker.
