Troubleshooting Tip: Local RADIUS service fails to start

Restarting the radiusd.service from the CLI does not help.  

systemctl restart radiusd
A dependency job for radiusd.service failed. See 'journalctl -xe' for details.

systemctl status radiusd

In this situation, it is recommended to reinstall the package. 

For this procedure, FortiNAC will require internet connectivity.

1. Uninstall all RADIUS packages:   

>yum -y remove "freeradius*"

2. Confirm no RADIUS packages are returned:

>rpm -qa | grep radius

3. Reboot the appliance (this will automatically re-install and configure FreeRADIUS).
   
   
4. Confirm RADIUS packages are installed again:

>rpm -qa | grep radius

freeradius-3.0.21-1.x86_64

freeradius-config-3.0.21-1.x86_64

freeradius-mysql-3.0.21-1.x86_64

freeradius-rest-3.0.21-1.x86_64

5. If no RADIUS packages are returned from the command above, it means there was no FreeRADIUS package installed, and it is necessary to install it manually. 

yum -y install freeradius

6. Check RADIUS service:

systemctl status radiusd

Debugging:

nacdebug -name RadiusManager true

nacdebug -name RadiusAccess true
