2019-12-22 22:42:50,215: WARNING/MainProcess] /root/miniconda3/lib/python3.7/site-packages/kombu/pidbox.py:74: UserWarning: A node named celery@Linux is already using this process mailbox!
Maybe you forgot to shutdown the other node or did not do so properly?
Or if you meant to start multiple nodes on the same host please make sure
you give each node a unique node name!

运行脚本 有如下报错：

The message has been ignored and discarded.
Did you remember to import the module containing this task?
Or maybe you're using relative imports?

for more information.
The full contents of the message body was:
'[["log"], {}, {"callbacks": null, "errbacks": null, "chain": null, "chord": null}]' (82b)
Traceback (most recent call last):
File "/root/miniconda3/lib/python3.7/site-packages/celery/worker/consumer/consumer.py", line 559, in on_task_received
strategy = strategies[type_]
KeyError: 'task_log.worker'
启动程序，应该是输出三次，结果输出一次或者一次也没有输出卡在那里
原因：运行了两次celery worker 命令
关闭一个命令就好了
