=====Systemctl=====

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

It provides a lot more information.  

Here is a very good [[https://www.digitalocean.com/community/tutorials/how-to-use-systemctl-to-manage-systemd-services-and-units | link]] to more infromation and options available in systemctl



====Starting and Stopping Services====
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.
    
====Finding out what Services are running====

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
