📘 Distribution Commands & Quick Fixes

Navigating different distributions requires knowing the right "flavor" of command.

🔧 Common Issue: "Permission Denied" on SSH

Fix: Ensure your private key has the correct permissions. Run chmod 600 ~/.ssh/id_rsa. Also, check /etc/ssh/sshd_config to ensure PubkeyAuthentication is set to yes.

🔧 Common Issue: Disk Space Full (/var/log)

Fix: Use du -sh /var/log/* to find the culprit. Clear old journal logs with journalctl --vacuum-time=7d.

💡 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 Login: Never allow direct root SSH access. Use a standard user with sudo privileges and SSH keys.

3. Document Everything: Maintain a "Change Log" for every configuration tweak. This is vital for troubleshooting months down the line.

4. Automate Early: Even for a single server, use a basic Ansible playbook for the initial hardening so your "Gold Image" is repeatable.
