🚀 Getting Started & Fixing Issues

⌨️ Essential Commands Across Distributions

While most commands are universal, package management differs by "family."

Task	Debian/Ubuntu (apt)	RHEL/Rocky (dnf)	Arch Linux (pacman)
Update Lists	`sudo apt update`	`sudo dnf check-update`	`sudo pacman -Sy`
Install Package	`sudo apt install X`	`sudo dnf install X`	`sudo pacman -S X`
Check Services	`systemctl status X`	`systemctl status X`	`systemctl status X`
Network Info	`ip addr show`	`ip addr show`	`ip addr show`

🛠️ Common Fixes for Typical Issues

Permission Denied: Ensure your user is in the sudo or wheel group. Use ls -l to check ownership.
Full Disk Space: Use du -sh /* to find large directories. Clean logs with journalctl --vacuum-time=2d.
SSH Connection Refused: Check if the service is running (systemctl status sshd) and ensure Port 22 is open in the firewall.

💡 Tips for Successful Server Installation

Use LVM (Logical Volume Management): Always partition with LVM to allow for easy disk resizing in the future.
Minimal Install: Only install the packages you need. This reduces the attack surface and improves performance.
SSH Key Authentication: Disable password-based logins immediately in favor of SSH keys for better security.
Documentation: Maintain an "Operational Runbook" detailing every custom change made to the baseline OS.
