Centos 7. Freeradius fails to start on boot
- by Alex
I was messing around with FreeRADIUS and MySQL (MariaDB) and it seems FreeRADIUS service can't start properly on startup. But it starts fine using root user or in debug mode (radiusd -X) and works just fine! Debug mode shows no errors.
systemctl command shows that radiusd.service has failed to start.

After seeing this I tried to replicate the problem, killed mariadb.service and started to run debug mode again. And it spits out the same problem as in the radius.log.
I tried disabling iptables and firewalld and rebooting, but no luck:
systemctl disable iptables
systemctl disable firewalld
So maybe the problem is in the process startup order or delay of some kind. Maybe FreeRADIUS's SQL module can't connect to not yet started MariaDB? If it, how can I fix this?
In earlier versions of RHEL/CENTOS I know you easily see service start order in like rc.d or stuff, now IDK. I am new to this fancy "systemd", "systemctl", "firewalld" stuff Centos 7 introduced so sorry I'm a little bit confused. Also this new FreeRADIUS 3 structure...
PS. MariaDB is enabled on startup, credentials in FR DB configuration are correct
A little update:
cat /etc/systemd/system/multi-user.target.wants/radiusd.service output:
