📖  Essential Commands & Troubleshooting

1. Package Management by Distribution Family

2. Fixing Common Linux Issues

• "Permission Denied" Errors: Use ls -l to check ownership. Fix with sudo chown user:group [file] or sudo chmod 755 [directory].

• SSH Connection Timed Out: Ensure the service is running with sudo systemctl status ssh. Check your firewall: sudo ufw allow 22.

• Disk is Full: Identify large files using du -sh /* | sort -h. Clean temporary files with sudo apt clean or sudo dnf clean all.

• High CPU Usage: Run htop or top to identify the rogue process. Use kill -9 [PID] only as a last resort.

💡 Tips for a Successful Server Setup

1. Documentation is King: Always maintain a README.md or a private Wiki documenting every configuration change made to the server.

2. Separate Partitions: During installation, keep /home, /var, and / on separate partitions to prevent log files from crashing the entire system if they fill up the disk.

3. Harden SSH Immediately: Change the default port 22, disable RootLogin, and enforce SSH Key Authentication only.

4. Automate Backups: Never rely on manual backups. Use rsync or tools like BorgBackup and schedule them via cron.
