왜 0.0 ELB 인스턴스입니까?

내 환경에 내 Rails 앱 배포를 성공적으로 완료했지만 모니터링 대시 보드에 0.0 ELB 인스턴스가있는 것을 볼 수 있는데 그 이유는 무엇입니까?

배포 할 때 내 로그는 다음과 같습니다.

INFO: Deploying new version to instance(s).                         
INFO: New application version was deployed to running EC2 instances.
INFO: Environment update completed successfully.                    

현재 내 앱을 방문 할 때만 빈 페이지가 표시됩니다. 0.0 ELB 인스턴스가 있기 때문이라고 가정합니다.

어떻게 해결할까요?

다음은 스냅 샷입니다.

  According to the PID file '/var/app/support/pids/passenger.pid',
  Phusion Passenger Standalone doesn't seem to be running.

  If you know that Phusion Passenger Standalone *is* running then one of these
  might be the cause of this error:

   * The Phusion Passenger Standalone instance that you want to stop isn't running
     on port 80, but on another port. If this is the case then you
     should specify the right port with --port.
     If the instance is listening on a Unix socket file instead of a TCP port,
     then please specify the PID file's filename with --pid-file.
   * The instance that you want to stop has stored its PID file in a non-standard
     location. In this case please specify the right PID file with --pid-file.
