Ok..wow...first off, if you're running snort in IDS mode, you'll want to add -D for daemon mode. My rc.snort file has:
/usr/local/bin/snort -q -i eth1 -D -o -c /etc/snort/snort.conf
You won't see anything in the console... If you're NOT running wanting to run in daemon mode then add the -v switch to see what's going on...I use that when using snort to sniff an active connection.
Second, in RedHat you'll need to muck with the SysV stuff, or add the above line or your own to rc.local to start on boot.
Third, make sure your snort.conf has the output database line uncommented. I use both ACID and syslog for my setup here. Hope this helps.
