π Tips for a Successful Server Installation
Β
-
Partition Wisely: Always separate
/var,/home, and/to prevent a log explosion from crashing the entire system. -
SSH Hardening: Immediately disable root login and switch to SSH key-based authentication. Change the default port 22 to a non-standard port to reduce bot attacks.
-
Documentation: Maintain an operational runbook. If a configuration change is made, it should be reflected in your Ansible playbooks or a simple markdown file.
