🧠 Expert Guide: Getting Started & Fixing Issues

1. Core Commands Across Distributions

While package managers differ, the logic remains the same. Use this quick reference:

2. Fixing Common Issues

• Permission Denied: Instead of chmod 777 (which is dangerous), use stat to check ownership and apply chown user:group followed by chmod 644 (files) or 755 (folders).

• Disk Full: Use du -sh /* 2>/dev/null | sort -h to find which directory is eating space. Often, it's unrotated logs in /var/log.

• Service Won't Start: Always check the specific unit status: systemctl status service_name -l.

3. Tips for a Successful Server Setup

• Minimal Install: Always start with the "Minimal" or "NetInstall" version of a distro to reduce the attack surface.

• Separate Partitions: Keep /home, /var, and / on separate partitions to prevent log overflows from crashing the entire system.

• SSH Key-Only Auth: Disable password authentication in /etc/ssh/sshd_config immediately after setup.
