Independent/Advanced: 🏹 Arch Linux, Gentoo, ⚓ Slackware.
Starting with a new distribution can be daunting. I’ve compiled this quick-reference guide to help you navigate the different package managers and system basics.
| Task | Ubuntu/Debian (APT) | RHEL/CentOS/Alma (DNF) | Arch Linux (Pacman) | openSUSE (Zypper) |
| Update Lists | sudo apt update | sudo dnf check-update | sudo pacman -Sy | sudo zypper ref |
| Install App | sudo apt install | sudo dnf install | sudo pacman -S | sudo zypper in |
| Full Upgrade | sudo apt upgrade | sudo dnf upgrade | sudo pacman -Syu | sudo zypper up |
| Remove App | sudo apt remove | sudo dnf remove | sudo pacman -R | sudo zypper rm |
Check Disk Space:df -h (Human-readable format).
Monitor Resources:htop or top (See what's eating your RAM/CPU).
Check Logs:journalctl -xe (The first place to look when a service fails).
Network Status:ip a (To find your IP address) or ss -tulpn (To see open ports).
In my experience, 90% of Linux "disasters" stem from a few recurring issues. Here is how I approach them:
🔒 SSH Login Failures: Usually caused by incorrect permissions on the .ssh folder (should be 700) or the authorized_keys file (should be 600).
💾 Disk Full: Use du -sh /* | sort -h to find which directory is consuming space. Often, it's /var/log getting bloated.
⚙️ Service Won't Start: Use systemctl status followed by journalctl -u to see the specific error line.
🌐 DNS Issues: If you can ping IPs but not names, check /etc/resolv.conf. Switching to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare) often fixes it.
A successful installation isn't just about clicking "Next." Follow these expert principles:
Hardening from Minute One: Disable Root SSH login and change the default port. Always use SSH keys instead of passwords. 🛡️
LVM is Your Friend: Always use Logical Volume Management (LVM). It allows you to resize partitions later without reformatting.
Automate Updates: For Debian/Ubuntu, use unattended-upgrades. For RHEL-based, use dnf-automatic. Safety first!
Monitoring & Backups: Never go live without a 3-2-1 backup strategy (3 copies, 2 media types, 1 offsite).
Documentation: Document every custom configuration change in a /root/README file. Future-you will thank me.
