Error while restarting dhcpd

Someone can help me here?
Im using systemctl restart dhcpd

Are you trying to run a DHCP server or do you mean to be running the client? To run the client, you probably want something more along the lines of systemctl restart NetworkManager.

Im trying to restart the service of dhcpd
This is for doing a PXE Server to do a Boot of a network operating system
The thing is Im following a tutorial but just got with this error and Im stuck with it
First I have to run this 3 commands
systemctl restart xinetd
systemctl restart httpd
systemclt restart dhcpd
and then this 3 others
systemctl enable xinetd
systemctl enable httpd
systemctl enable dhcpd

I just asked because you didn’t have a hostname set. Usually when people are setting up a DHCP server, they first configure a static hostname and IP address.

You will probably need to find a more detailed error message to figure out what is wrong. Can you run the command the service is running by hand in the foreground and see more of the error messages? I.e.:

# /usr/sbin/dhcpd -f -cf /etc/dhcpd.conf -user dhcpd -group dhcpd --no-pid

If DHCPDARGS are defined in /etc/sysconfig/dhcpd, be sure to include those as well.
