RabbitMQ的Pika超時問題

Question

我遇到了Pika超時錯誤的問題。 相同的代碼（下面）在其他環境中也可以正常工作，但是在此環境中失敗。

connection = pika.BlockingConnection(pika.ConnectionParameters(host=host))

rabbitmqctl狀態

    [{pid,30059},

 {processes,[{limit,1048576},{used,6763}]},
 {run_queue,0},
 {uptime,3298}]
...done.

有人打過嗎？ 我假設這是一個Rabbitmq配置問題

檢查RabbitMQ日志，您可能需要提供登錄憑據：

pika.BlockingConnection(pika.ConnectionParameters(host, port=port, virtual_host=vhost, credentials=pika.credentials.PlainCredentials(username, password)))
