systemctl status service name:
systemctl status httpd
● httpd.service - The Apache HTTP Server
Loaded: loaded (/usr/lib/systemd/system/httpd.service; disabled; vendor preset: disabled)
Active: inactive (dead)
on the above example you can see disabled that means the httpd is not enabled at startup. If you do systemctl enable httpd then check with systemctl status httpd then you will see enable && on earlier version of linux machines chkconfig --list was used for this but now with systemd it is different.
