cPanel and WHM is essentially a large number of different programs all running under a single graphical interface. The interface will invoke scripts when specific functions are done inside the software. If you click the restart ssh link inside WHM for example that will call the restart function for your ssh server which is the command /usr/local/cpanel/scripts/restartsrv sshd . This guide provides a list of all available services that can be restarted manually inside a cPanel VPS Servers from the command line. You should always attempt to first restart services using the /usr/local/cpanel/scripts/restartsrv. If this does not work you can attempt to force services to restart using /etc/rc.d/init.d/ for CentOS 6 or systemctl restart service-name.service for CentOS 7 cPanel servers.
Restart services in the WHM interface
Unless problems prevent this, you can restart most services in WHM’s Restart Services interface (Home >> Restart Services).
Restart cPanel services SSH
If a service will not restart from WHM, then you can use the /usr/local/cpanel/scripts/restartsrv service command to attempt to restart cPanel services using SSH. When you run this command, replace service with the correct value for that service, we have included all of the possible services you can restart with this script below with an example

/usr/local/cpanel/scripts/restartsrv xinetdRestart cPanel Services – Direct Service Restart
If the /usr/local/cpanel/scripts/restartsrv script does not restart the service, you can attempt to restart the service directly. For cPanel servers that run Rocky Linux, AlamLinux, CentOS, CloudLinux™, or Red Hat® Enterprise Linux (RHEL) 7 or 8 run the following command, where “service” is the path to the service:
systemctl restart service-name.service
