Linux Server Infrastructure: From Installation to Service Deployment

This article introduces Linux server installation and basic service deployment, suitable for zero-basic learners. Linux is the preferred choice for servers due to its stability and security. Unlike the desktop version, the server version focuses on performance optimization. Installation preparation: Minimum hardware requirements are 1-core CPU, 2GB memory, and 20GB hard disk (SSD is better). Recommended distributions include CentOS (enterprise-grade stability) or Ubuntu Server (user-friendly for beginners). Taking CentOS 7 as an example, download the minimal ISO, perform automatic partitioning, set the root password, and restart. Basic configuration: Configure a static IP (to avoid changes), create a regular user, and disable direct root login. The firewall should only open necessary ports (e.g., 80 for web services). Core service deployment: Practical deployment of Nginx (web server), vsftpd (FTP server), and MariaDB (database), with installation, startup, and verification methods introduced respectively. Summary: The process is minimal installation → network security configuration → core service deployment. Security and stability are key, and subsequent exploration can be done on complex architectures (e.g., LAMP/LNMP).
