Asterisk not running

While i install a fresh copy of freepbx which includes asterisk , mysql and webserver for my VoIP communication it works fine on the first use. Meanwhile if i restart my freepbx server , the asterisk stops working and neither gives any chance to restore the config’s. I have tried re-installations many times, Can you please suggest the possible way-out.


After reboot if you logon as root ans type “amportal start” does Asterisk start running then?
