The post lists the new systemctl command in RHEL 7 with the legacy service/chkconfig command. Legacy commands service and chkconfig are still compatible in RHEL 7 with forwarding/redirecting information output of prevailing command systemctl.
Starting, stopping and checking status of a service
Start a service:
# systemctl start [service_name]
for example:
# systemctl start multipathd
Stop a service:
# systemctl stop [service_name]
for example:
# systemctl stop multipathd
Check status of a service:
# systemctl status [service_name]
for example:
# systemctl status multipathd
Enabling or disabling auto-start of a service
Enable auto-start a service at boot (equivalent of chkconfig):
# systemctl enable [service_name]
for example:
# systemctl enable multipathd
Disable auto-start a service at boot:
# systemctl disable [service_name]
for exmaple:
# systemctl disable multipathd

List active service units:
# systemctl list-units --type service
List enabled/disabled status of all installed service units:
# systemctl list-unit-files --type service
