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:
