What should I do if Nginx won't start after a config change?
Restore the backup config (cp backup file back), run nginx -t to verify the old config, then systemctl restart nginx. If the backup also fails, check nginx -t output for syntax errors. As a last resort, use the default config (sudo cp /etc/nginx/sites-available/default /etc/nginx/sites-enabled/).

Yes. Keep Nginx config files in your project repo or a separate config repo. This gives you version history, easy rollback (git checkout), team collaboration, and documentation of all changes. Copy to /etc/nginx during deployment.
