🚀 Getting Started Across Distributions

Starting with a new distro can be daunting. I've compiled the essential "First Steps" commands for the three major families.

1. Package Management (The Vital First Step)

Before doing anything, ensure your system is current:

• Ubuntu/Debian:sudo apt update && sudo apt upgrade -y

• RHEL/CentOS/Rocky:sudo dnf update

• Arch Linux:sudo pacman -Syu

2. Fixing Common Connectivity Issues

If you can't reach the web, check your status:

• Check IP:ip a

• Test Route:ping -c 4 google.com

• Check DNS:cat /etc/resolv.conf

• Restart Network:sudo systemctl restart NetworkManager

3. Essential Troubleshooting Commands

• Check Disk Space:df -h (Look for 100% usage in /).

• Monitor Processes:top or htop (To find memory-hungry apps).

• View Logs:journalctl -xe (The "Golden Command" for finding why a service failed).

💡 Tips for a Successful Server Setup

1. Use LVM (Logical Volume Management): Always partition with LVM. It allows you to resize partitions later without reformatting.

2. Disable Root SSH: Never allow direct root login. Use SSH keys and sudo for better auditing.

3. Time Sync is Crucial: Ensure chrony or ntp is running. Inconsistent system clocks break databases and security certificates.

4. Document Everything: Create a "Runbook" for every manual change made to the server.
