Using CentOS: A Guide for System Administrators

CentOS is an open source operating system based on RedHatEnterpriseLinux, suitable for server environments. 1. Select the appropriate media and options during installation and configure network, firewall and user permissions. 2. Use useradd, usermod and systemctl commands to manage users and services, and update software packages regularly. 3. Basic operations include using yum installation software and systemctl management services, and advanced features such as SELinux to enhance security. 4. Check the system log to solve common errors. Optimizing performance requires monitoring resources and cleaning of unnecessary files.

Docker on Linux: Containerization for Linux Systems

Docker on Linux: Containerization for Linux Systems

Docker is important on Linux because Linux is its native platform that provides rich tools and community support. 1. Install Docker: Use sudoapt-getupdate and sudoapt-getinstalldocker-cedocker-ce-clicotainerd.io. 2. Create and manage containers: Use dockerrun commands, such as dockerrun-d--namemynginx-p80:80nginx. 3. Write Dockerfile: Optimize the image size and use multi-stage construction. 4. Optimization and debugging: Use dockerlogs and dockerex

Linux: A Deep Dive into Its Fundamental Parts

Linux: A Deep Dive into Its Fundamental Parts

The core components of Linux include kernel, file system, shell, user and kernel space, device drivers, and performance optimization and best practices. 1) The kernel is the core of the system, managing hardware, memory and processes. 2) The file system organizes data and supports multiple types such as ext4, Btrfs and XFS. 3) Shell is the command center for users to interact with the system and supports scripting. 4) Separate user space from kernel space to ensure system stability. 5) The device driver connects the hardware to the operating system. 6) Performance optimization includes tuning system configuration and following best practices.

Docker's Purpose: Simplifying Application Deployment

Docker's Purpose: Simplifying Application Deployment

The purpose of Docker is to simplify application deployment and ensure that applications run consistently in different environments through containerization technology. 1) Docker solves the environmental differences problem by packaging applications and dependencies into containers. 2) Create images using Dockerfile to ensure that the application runs consistently anywhere. 3) Docker's working principle is based on images and containers, and uses the namespace and control groups of the Linux kernel to achieve isolation and resource management. 4) The basic usage includes pulling and running images from DockerHub, and the advanced usage involves managing multi-container applications using DockerCompose. 5) Common errors such as image building failure and container failure to start, you can debug through logs and network configuration. 6) Performance optimization construction
