jpg The broker delivers tasks to the worker nodes. A worker node is a networked machine running celeryd. This can be one or more machines depending on the workload. The result of the task can be stored to import using the -I option to celeryd: $ celeryd -l info -I tasks,handlers This can be a single, or a comma separated list of task modules to import when celeryd starts. Running the celery worker will run the worker server in the foreground, so we can see what’s going on in the terminal: $ celeryd --loglevel=INFO In production you will probably want to run the worker in the background as a daemon
