celery使用rabbitmq报错[Errno 104] Connection reset by peer.

写好celery任务文件,使用celery -A app worker --loglevel=info启动时,报告如下错误:

[2019-01-29 01:19:26,680: ERROR/MainProcess] consumer: Cannot connect to amqp://sunlight:**@127.0.0.1:5672/celery: [Errno 104] Connection reset by peer.
Trying again in 4.00 seconds...

检查了很久,终于发现是celery配置的broker的url写错了,

rabbitmqctl add_user sunlight sunlight123

rabbitmqctl add_vhost /celery

rabbitmqctl set_permissions -p /celery sunlight   ".*"   ".*"   ".*"

app = Celery(__name__, broker="amqp://sunlight:sunlight123@localhost:5672/celery", backend="redis://localhost")

上门的标红处,显然是错误的,应该替换为如下:

app = Celery(__name__, broker="amqp://sunlight:sunlight123@localhost:5672//celery", backend="redis://localhost")

即可解决问题。
