freeradius startup error (code=exited, status=1/FAILURE) - centos

Question

I am new to freeradius. I have installed freeradius on centos-7 and planned to manage it using daloradius.
After installing freeradius it was working fine and started normally by "systemctl start radiusd".
but after installing and configuring MariaDB, freeradius is not starting while working with "radiusd -X" is working.
following is the error message:
[root#radiusx1 ~]# systemctl start radiusd
Warning: radiusd.service changed on disk. Run 'systemctl daemon-reload' to reload units.
Job for radiusd.service failed because the control process exited with error code. See "systemctl status radiusd.service" and "journalctl -xe" for details.
[root#radiusx1 ~]# systemctl status radiusd

Please help me to sort out this issue.
Any help will be appreciated.

Answer 1

That's likely a permissions issue. -X runs the process as the current user, whereas -C will change to the configured user/group.
You can use this invocation to perform a config check with debugging info written to stdout.
/usr/sbin/radiusd -C -lstdout -xxx
-C config check
-lstdout override configured logging destination and set to stdout.
-xxx set debugging to level 3. Should show any useful output.
Report back with the output if it doesn't make sense to you, and i'll interpret.

Answer 2

I match same issue, after check by Arran's command that will let you know reason, but suggest you to enable radius by "radius -X" under root environment, that will give you root cause, as follow my issue:
Under user environment:
[cisco#frank ~]$ /usr/sbin/radiusd -C -lstdout -xxx
