How to Perform a Reboot in WHM
Rebooting your server can be necessary from time to time, if you’ve applied certain system updates or your server is under high load.
In WHM there are two types of reboot:
Forceful Reboot: This immediately restarts the server without letting any processes finish executing. This should be avoided unless absolutely necessary.
Graceful Reboot: This lets running operating finish executing before restarting the server. This is the option you should use most often.
First, login to the WHM control panel.
Next, navigate to either Forceful Reboot, or Graceful Reboot.
Just click Proceed to start the reboot of your server.
