Freeradius (radiusd) service can't start on boot but can start manually

I managed to setup freeradius server on Centos 7 using compiled source at ftp://ftp.freeradius.org/pub/freeradius/freeradius-server-3.0.18.tar.gz Everything works perfectly fine except, the service can't run every time after reboot. I have to issue command... sudo systemctl start radiusd The service run successfully. Below are the logs ● radiusd.service - FreeRADIUS config by ME.

I just don't know where else to look because this is the only log that i found.
