Rebooting is sometimes required — after a kernel update, to apply certain configuration changes, or to recover from a stuck process. Done correctly, it takes seconds and causes minimal disruption.

Before You Reboot

• Check if a reboot is actually required: test -f /var/run/reboot-required && echo "Reboot needed"
• Warn any logged-in users, if applicable: who
• Make sure any critical services (databases, web apps) will restart automatically on boot

Step 1 — Check Enabled Services Will Auto-Start

sudo systemctl is-enabled nginx mysql

If a service shows disabled, enable it so it comes back after reboot:

sudo systemctl enable nginx

Step 2 — Reboot Immediately

sudo reboot

Step 3 — Schedule a Delayed Reboot (Optional)

To reboot after a delay, giving time to warn users or finish tasks:

sudo shutdown -r +5

This reboots in 5 minutes. Cancel a scheduled reboot with:

sudo shutdown -c

Step 4 — Reconnect and Verify

Wait 30–60 seconds, then reconnect:

ssh deploy@YOUR_SERVER_IP

Check system uptime to confirm the reboot happened:

uptime

Step 5 — Verify Services Came Back Up

sudo systemctl --failed

This lists any service that failed to start. Investigate and restart individually if needed:

sudo systemctl restart SERVICE_NAME

What If the VPS Doesn't Come Back Online?

1. Wait a few minutes — some reboots take longer if filesystem checks run
2. Use your hosting provider's web-based console/VNC to see boot output directly
3. Check for filesystem errors reported during boot
4. If the issue persists, contact your provider's support with console output

Common Errors

SSH connection refused after reboot — the server may still be booting; wait another minute before assuming a problem.

A service didn't restart — it likely wasn't enabled to start on boot; fix with systemctl enable SERVICE_NAME.

Best Practices

• Schedule reboots during low-traffic maintenance windows
• Always verify systemctl --failed after every reboot
• Keep a recent backup before rebooting after major system changes

FAQ

How long does a typical VPS reboot take?
Usually 15–60 seconds, though it can take longer if disk checks or a kernel update are involved.
