Question

我在rackspace主机上设置了一个rabbitmq服务器。我已经完成了（python）教程。现在我想做同样的'hello world'教程，但是我没有使用示例脚本连接localhost，而是想在两台完全不同的机器上运行send.py和receive.py。< / p>

我一直在阅读文档，但我不认为我看到它们是如何组合在一起的。我认为我可能需要做的是添加一个用户：

sudo rabbitmqctl add_user xxx yyy

我确定它出现了list_users

$ sudo rabbitmqctl list_users
Listing users ...
guest   [administrator]
xxx []

现在我让我的receive.py在连接到localhost的服务器上运行。但是send.py，我转向了像Linux SBC这样的Raspberry，并使用amqpstorm重写：

#!/usr/bin/env python3
import logging
from amqpstorm import Connection, Message

logging.basicConfig(level=logging.DEBUG)

def publisher():
    with Connection('abc.def.com', 'xxx', 'yyy') as connection:
        with connection.channel() as channel:
            channel.queue.declare(queue='hello')
            properties = {
                'content_type': 'text/plain',
                'headers': {'key': 'value'}
            }

            message = Message.create(channel, 'Vennlig Hilsen', properties)
            message.publish('hello')

if __name__ == '__main__':
    publisher()

这会产生以下错误：

# ./send.py 
DEBUG:amqpstorm.connection:Connection Opening
DEBUG:amqpstorm.channel0:Frame Received: Connection.Start
DEBUG:amqpstorm.channel0:Frame Sent: Connection.StartOk
DEBUG:amqpstorm.channel0:Frame Received: Connection.Tune
DEBUG:amqpstorm.channel0:Frame Sent: Connection.TuneOk
DEBUG:amqpstorm.channel0:Frame Sent: Connection.Open
Traceback (most recent call last):
  File "./xend.py", line 22, in <module>
    publisher()
  File "./xend.py", line 9, in publisher
    with Connection('abc.def.com', 'xxx', 'yay') as connection:
  File "/usr/lib/python3/dist-packages/amqpstorm/connection.py", line 70, in __init__
    self.open()
  File "/usr/lib/python3/dist-packages/amqpstorm/connection.py", line 191, in open
    self._wait_for_connection_state(state=Stateful.OPEN)
  File "/usr/lib/python3/dist-packages/amqpstorm/connection.py", line 314, in _wait_for_connection_state
    raise AMQPConnectionError('Connection timed out')
amqpstorm.exception.AMQPConnectionError: Connection timed out

它会很快吐出前6个DEBUG行，然后因某种最终的超时错误而停顿。

我是否走在正确的道路上？或者吠叫错误的树？我是否需要做更多配置我的用户（除了添加它之外我没有做任何其他事情）？除了journalctl，还有什么地方可以看到服务器的其他日志记录吗？

$ tail -f /var/log/rabbitmq/rabbit\@server5.log

                             'connection.open'}}

这告诉我，我必须另外做一些事情才能授权xxx用户？

根据您的RabbitMQ日志，您似乎忘记为新用户设置适当的权限。

sudo rabbitmqctl set_permissions my_user ".*" ".*" ".*"

如果您使用的是其他虚拟主机，请不要忘记也为该虚拟主机设置权限。

sudo rabbitmqctl set_permissions -p my_virtual_host my_user ".*" ".*" ".*"

您可以在官方文档here中阅读有关这些选项的更多信息。

两台不同的机器通过rabbitmq公开谈话？
