Linux Tutorial
This is a practical, step-by-step guide to Linux system administration, command-line usage, and development environment setup, written from the perspective of a Java developer. The tutorial is structured as a sequence of terminal commands with explanations, teaching system administration through direct modification of plain-text configuration files. It provides separate workflows for CentOS, Ubuntu, and Kali Linux, covering both yum and apt package managers with equivalent commands for each operation.
The guide emphasizes a security-first workflow, walking through firewall configuration, SSH key authentication, and user permission management. It assumes all system installations happen inside virtual machines, with dedicated instructions for provisioning in VMware and VirtualBox. The content covers the full lifecycle of a Linux system, from installation and network configuration through package management, file handling, and service control.
The tutorial includes procedures for configuring CentOS systems, setting up Java development environments, and managing network interfaces after cloning virtual machines. It also covers file and archive manipulation, including working with JAR files, and provides a safe deletion mechanism that redirects file removal to a trash folder with automatic expiration. The documentation is organized as a Linux command-line reference with practical examples for common administrative tasks.
