📖 Getting Started & Common Fixes
Each distribution family has its own "personality." Here is a quick reference for managing them effectively.
1. Package Management (The Big Three)
| Family | Distribution | Primary Command |
| Debian/Ubuntu | Ubuntu, Debian, Mint | sudo apt update && sudo apt upgrade |
| RHEL/Fedora | RHEL, Rocky, Alma, CentOS | sudo dnf check-update && sudo dnf upgrade |
| Arch | Arch Linux, Manjaro | sudo pacman -Syu |
2. Fixing Common "Broken" States
-
Permission Denied: Use
ls -lto check ownership. Fix withsudo chown user:group /pathorsudo chmod 755 /path. -
Service Won't Start: Check the status immediately:
systemctl status service_name. Usejournalctl -xeto see the exact error log. -
Disk Space Full: Find the culprit with
du -sh /* | sort -h. Clear logs withjournalctl --vacuum-time=7d.
💡 Tips for a Successful Server Setup
For a production-ready environment, I recommend following these best practices:
-
🔑 Disable Root SSH: Always use a standard user with
sudoprivileges and disable password-based root login in/etc/ssh/sshd_config. -
🛡️ Use a Firewall from Day 1: Even if the server is internal, enable
ufworfirewalldto limit traffic to strictly necessary ports (22, 80, 443). -
⏱️ Synchronize Time: Ensure
chronyorntpis running. Inconsistent system clocks cause major issues with logs, databases, and authentication tokens. -
📜 Documentation is King: Keep a "Runbook." If you change a configuration file, comment on why you changed it and when.
