Systemctl status dhcpd finally
responded after I created the .service file like you said. Based on a
yum install in a test server, I've placed the dhcpd.service file in
/usr/lib/systemd/system and also created dhcrelay.service.
Now I know a little more about systemd and what to look for in future compiling issues. <br></div><br><div></div><div>Thank you again!

Though Rick is right about there being a pre-compiled version in<br>
RHEL/CentOS, it's kind of old. Even though RedHat probably does a good<br>
job of back porting fixes, you can expect many people to advise you to<br>
use the official release when asking on this list.<br>
<br>
Compiling you own does work best if you're comfortable with compiling<br>
stuff and writing your own configuration and service files.<br>
<br>
The ISC DHCP source doesn't contain a systemd ".service" file so you<br>
have to make one yourself. The contents depend on how you configured<br>
dhcpd regarding where executables and configuration and lease files are<br>
placed.<br>
<br>
With "--prefix=/usr" the executable is installed in /usr/sbin/dhcpd.<br>
The lease files seem to be placed in "/var/db" from the output you<br>
pasted.<br>
<br>
The systemd service file from a CentOS 7 vendor version of ISC dhcpd is<br>
placed in /usr/lib/systemd/system/dhcpd.service when installed and<br>
looks like this:<br>
<br>
[Unit]<br>

<br>

<br>

<br>
I'm not sure if a plain build can use this, but you could try.<br>
<br>
We configure with the following command:<br>
<br>
CFLAGS="-Wno-unused-but-set-variable" ./configure --prefix=/usr \<br>
--with-srv-lease-file=/var/lib/dhcpd/dhcpd.leases \<br>
--with-srv-pid-file=/var/run/dhcpd.pid \<br>
--enable-failover --enable-execute --enable-binary-leases<br>
<br>
We use a service unit file (in /etc/systemd/system/dhcpd.service to<br>
override any built in) with the following contents:<br>
<br>
[Unit]<br>
Description=DHCPv4 Server Daemon<br>
Documentation=man:dhcpd(8) man:dhcpd.conf(5)<br>
Wants=network-online.target<br>

<br>
