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

寫好celery任務文件，使用celery -A app worker --loglevel=info啓動時，報告以下錯誤：

[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...

 

檢查了好久，終於發現是celery配置的broker的url寫錯了，

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")

上門的標紅處，顯然是錯誤的，應該替換爲以下：

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

便可解決問題。
