Celery worker 并通过一个命令击败负载

Question

有没有一种方法可以启动 celery worker 并用一个命令击败？我想使用 Fabric 将 celery 添加到我的自动部署过程中。

我当前正在运行:

celery -A prj worker -B

其次是

celery -A prj beat -l info -S django

但是，第一个命令启动了工作程序，并且不允许运行下一个命令(启动节拍)，因为出现了工作程序启动消息。

有没有办法避免出现启动消息？或者在一个命令中执行这两项操作？也许甚至有办法从我的 Django 配置启动这些？

谢谢!

Celery 允许您在同一进程中运行工作线程和节拍(主要用于开发目的)。查看celeryworker的帮助:

> celery worker -h

...

Embedded Beat Options:
  -B, --beat            Also run the celery beat periodic task scheduler. Please note that there must only be
                        one instance of this service. .. note:: -B is meant to be used for development
                        purposes. For production environment, you need to start celery beat separately.
  -s SCHEDULE_FILENAME, --schedule-filename SCHEDULE_FILENAME, --schedule SCHEDULE_FILENAME
                        Path to the schedule database if running with the -B option. Defaults to celerybeat-
                        schedule. The extension ".db" may be appended to the filename. Apply optimization
                        profile. Supported: default, fair
  --scheduler SCHEDULER
                        Scheduler class to use. Default is celery.beat.PersistentScheduler

因此，组合命令(包括使用 django 调度程序)如下所示:

celery -A prj worker --beat --scheduler django --loglevel=info
