I installed everything on another server which didn’t have issue. Maybe I mess up something on the first time installation, or it was because of pre-GA code didn’t work. Don’t have much time to troubleshoot the old OpenStack environment now.

The best way is to start the service with the "neutron" user, it might output a reason for the service to fail (I know it seems to be running but it actually does not run). Also it might be good to run "echo $?" in order to try to spot the issue by the return code.
