randalee opened a new issue #16562:
URL: https://github.com/apache/superset/issues/16562


   I tried to run celerybeat and celery worker in the background for alarm and 
report functionality.
   I tried using init script with reference to 
"https://docs.celeryproject.org/en/v4.4.7/userguide/daemonizing.html";. However, 
those scripts that use "multi start" do not use superset app config.
   
   ### Expected results
   Normal background execution.
    celerybeat - success
    celery worker - error
   
   ### Actual results
   As a result of checking the log, the log accessing ampq instead of the redis.
   
   #### Screenshots
   foreground - OK

   backgroud - Fail

   #### How to reproduce the bug
   **foreground**
   celery worker --app=superset.tasks.celery_app:app --pool=prefork -O fair -c 4
   
   **background**
   celery multi start worker --app=superset.tasks.celery_app:app --pool=prefork 
-O fair -c 4 --logfile='log'
   tail -f log
