🚀 Tips for a Successful Server Setup

Always Use Key-Based Auth: Disable password authentication in
/etc/ssh/sshd_configimmediately. -
Automate Updates: Use
unattended-upgrades(Ubuntu) ordnf-automatic(RHEL) for security patches. -
Monitor Early: Don't wait for a crash. Set up Prometheus or Zabbix during the initial build.
-
Document Everything: Maintain an operational runbook for every custom configuration change.
