What are the components and functions of a linux system
Linux system consists of nine main components: kernel, distribution, package manager, shell, desktop environment, file system, applications, services and drivers. Together, these components are responsible for managing computer resources, providing the user interface, managing software packages, and communicating with hardware. In addition, Linux systems also have the advantages of stability, customizability, open source, free and security.
Components of a Linux system
Linux is an open source operating system that consists of multiple components Composed, jointly responsible for operating the computer. These components include:
1. Kernel
- The core of the Linux system
- Manages computer resources (such as memory, CPU, and peripherals)
- Provides process scheduling, file system management and other basic functions
2. Release version
- Specific version of Linux system , composed of various software packages and tools
- Different distributions provide different functions and interfaces
3. Package manager
- Tools for managing software packages
- Allows installation, update and removal of software packages
4. Shells
- Users The command line interface for interacting with Linux systems
- Bash and Zsh are common shells
5. The desktop environment
- is User-provided graphical user interface (GUI)
- GNOME, KDE and XFCE are popular desktop environments
6. File system
- Organize and store the hierarchical structure of files and directories
- Ext4, Btrfs and ZFS are commonly used file systems in Linux
7. Applications
- Software programs used to perform specific tasks
- Text editors, web browsers, and media players are common applications
8. Service
- A program that runs in the background to provide specific functions
- Web servers, database servers and file sharing servers are common services
9. Drivers
- Allow the Linux system to communicate with hardware devices
- Sound card, graphics card and printer drivers are common drivers
Features
Linux systems provide the following features:
- Stability: Known for its reliability and fewer crashes
- Customizability: Can be customized to specific needs
- Open source: Allows users to access and modify the source code
- Free: The open source license allows free use and distribution
- Security Security: With powerful security features such as user permissions and firewall

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.
