One thing that come to my mind is selinux. Is it enabled and enforcing?
getenforce # check status
setenforce 0 # to set to permissive, if enforcing
Cheers,
Fred

Values are the same other then gexec. Swapping that doesn't resolve the issue
that no hosts are reported.
Though not exactly what you are doing, bringing up the services:
#!/bin/bash
service gmond stop
service gmetad stop
nginx
nginx -s reopen
nginx -s reload
service gmetad start
service gmond start
service ipfw3 stop
service ipfw3 start
It is all started as far as systemctl is concerned:
systemctl status gmond.service

I did just notice though that /var/lib/ganglia/rrds is NOT populated on the CentOS 8 system, whereas it is on my Ubuntu laptop. Also there is something peculiar going on with the network, because
even though iptables is not running anywhere the gmond/gmetad ports on the CO8 system are not visible from the Ubuntu system, but in the reverse direction they are.
A thread on this problem has been started here:
