π Fixing Common Linux Issues
Β
Β
In my experience, 90% of Linux "disasters" stem from a few recurring issues. Here is how I approach them:
Β
-
π SSH Login Failures: Usually caused by incorrect permissions on the
.sshfolder (should be700) or theauthorized_keysfile (should be600). -
πΎ Disk Full: Use
du -sh /* | sort -hto find which directory is consuming space. Often, it's/var/loggetting bloated. -
βοΈ Service Won't Start: Use
systemctl statusfollowed byjournalctl -uto see the specific error line. -
π DNS Issues: If you can ping IPs but not names, check
/etc/resolv.conf. Switching to8.8.8.8(Google) or1.1.1.1(Cloudflare) often fixes it.

π Tips for a Successful Server Setup
Β
Β
A successful installation isn't just about clicking "Next." Follow these expert principles:
Β
Β
-
Hardening from Minute One: Disable Root SSH login and change the default port. Always use SSH keys instead of passwords. π‘οΈ
-
LVM is Your Friend: Always use Logical Volume Management (LVM). It allows you to resize partitions later without reformatting.
-
Automate Updates: For Debian/Ubuntu, use
unattended-upgrades. For RHEL-based, usednf-automatic. Safety first! -
Monitoring & Backups: Never go live without a 3-2-1 backup strategy (3 copies, 2 media types, 1 offsite).
-
Documentation: Document every custom configuration change in a
/root/READMEfile. Future-you will thank me.
