This a major change in RHEL 7 and so far so good.

It provides a lot more information.

Here is a very good link to more infromation and options available in systemctl

Pretty basic stuff

To get a service started

systemctl start service-name

To stop a service

systemctl stop service-name

These does not return anything. So you need to check that the service is running. THere are 2 ways to do this:

1  systemctl status service name
  This will show you a green entry Active:  active (running) if the service is running
  
2 systemctl is-active service-name 

  This just retuns active or not
  

To ensure that the service restart on reboot of the server you need to ensure that the service is enabled

systemctl enable service name

This does not return anything. So to check that the service is enabled you again also have 2 options

1 systemctl status service
  
  Look on second line **Loaded** at the end of it it will mention enabled
  
2 systemctl is-enabled service name

  This just returns enabled if its enabled.
  

THis is a bit messier as there is so much information shown.

Easies way to do this is with

systemctl list-units 

This is nice and basic if you want moreinformation..ie is it running then use

systemctl list-units --all
