-
Permission Denied: Use
ls -lto check ownership. Fix withsudo chown user:group filenameorchmod 755 filename. -
Service Won't Start: Check status with
systemctl status service_name. Look for "Failed" lines. -

π‘ Tips for a Successful Server Setup
Β
I recommend following these four pillars for any new installation:
Β
-
Minimal Install: Always start with the "Minimal" ISO. Only install the packages you absolutely need to reduce the attack surface.
-
SSH Hardening: Disable
Root Loginand switch to SSH Key-based authentication immediately. Change the default port 22 to a custom high port. -
LVM Partitioning: Use Logical Volume Management (LVM). It allows you to resize partitions dynamically as your data grows.
-
Automated Time Sync: Ensure
chronyorntpis active. Accurate logs depend on perfectly synced system clocks.
