How to restart cPanel/WHM

Ever wanted to restart the cPanel/WHM system? There is no need to restart your operating system. You can restart only the cPanel/WHM system via a simple command.
You need to be logged in as root via SSH. Execute the following command:

# /scripts/restartsrv_cpsrvd
root@web [~]# /scripts/restartsrv_cpsrvd
