π‘ Tips for a Successful Server Setup
Β
Β
-
Always Use Key-Based Auth: Disable password-based SSH login immediately to prevent 99% of brute-force attacks.
-
Document Everything: Maintain a "Runbook." If you change a config file in
/etc/, comment why you changed it. -
Partition Wisely: Keep
/var/logand/homeon separate partitions to prevent a full log file from crashing the entire OS. -
Automate Early: Even for a single server, using a tool like Ansible ensures your setup is reproducible if hardware fails.
