Zero to Hero: A Guide to Installing Linux on a Server

This article introduces a Linux server installation guide suitable for beginners. Linux servers are secure, efficient, and ideal for high-concurrency tasks, making them fundamental for operations and maintenance. Before installation, the appropriate scenario should be chosen: either a local virtual machine (requiring software like VirtualBox and an Ubuntu Server ISO) or a cloud server (e.g., Alibaba Cloud ECS). Ubuntu Server 22.04 LTS is recommended. For local virtual machine installation: Create a virtual machine (with at least 2GB RAM and a 20GB dynamically allocated hard disk), mount the ISO for booting, select English for installation, use automatic partitioning, set a username and password, check the OpenSSH server option, and verify login after reboot. For cloud server installation: Create an instance on Alibaba Cloud (1 core, 2GB RAM, Ubuntu image) and connect via SSH (using keys for enhanced security). Post-installation verification includes executing `lsb_release -a` to check the version, using `ping` to test network connectivity, and running `sudo apt update` to verify permissions. Beginners should note password security, bridged networking for virtual machines, and installing tools like `vim`. Mastering minimal installation, remote connection, and permission management will enable smooth entry-level operations following the step-by-step instructions.
