问题描述
我正在尝试运行 RabbitMQ Python 教程，但与发件人在 virtualbox 主机和接收器上，并在 virtualbox 来宾机器上排队.所以我修改了提到的 send.py 代码，只将 localhost 替换为 192.168.1.5.当我运行它时，我收到以下错误:
I'm trying to run RabbitMQ Python tutorial but with sender on virtualbox host machine and receiver and queue on virtualbox guest machine. So I modified mentioned send.py code by only replacing localhost with 192.168.1.5. When I run it, i receive following error:
...
File "/home/damian/.virtualenvs/kivy_1.9/local/lib/python2.7/site-packages/pika/adapters/base_connection.py", line 153, in _check_state_on_disconnect
raise exceptions.ProbableAuthenticationError
pika.exceptions.ProbableAuthenticationError
rabbitmq-server 似乎正在运行，因为当我停止它时 send.py 给我:
rabbitmq-server seems to be running, because when I stop it send.py gives me:
...
File "/home/damian/.virtualenvs/kivy_1.9/local/lib/python2.7/site-packages/pika/adapters/blocking_connection.py", line 301, in _adapter_connect
raise exceptions.AMQPConnectionError(error)
pika.exceptions.AMQPConnectionError: Connection to 192.168.1.5:5672 failed: [Errno 111] Connection refused
这很有意义.
如何解决ProbableAuthenticationError?
主机是带有 Python 2.7.3 和 pika 0.9.14 的 Debian 7，来宾是带有 rabbitmq-server 3.4.3-2 的 Ubuntu 15.04
Host machine is Debian 7 with Python 2.7.3 and pika 0.9.14, guest is Ubuntu 15.04 with rabbitmq-server 3.4.3-2
推荐答案
这是因为您正尝试使用用户名和密码 guest 远程进行身份验证.从 RabbitMQ 3.3 开始，您需要创建一个新帐户才能使用远程，guest/guest只能在本地使用.
This is because you are trying to authenticate using the username and password guest remotely. Starting with RabbitMQ 3.3 you need to create a new account to use remotely, and guest/guest can only be used locally.
这取自变更日志此处.
25603 prevent access using the default guest/guest credentials except via localhost since (1.0.0)
可以通过从 loopback_users 中删除 guest 来修改 RabbitMQ 配置以允许使用 guest 帐户进行远程访问，但建议创建一个新用户以最好地遵循实践.
It's possible to modify the RabbitMQ configuration to allow remote access using the guest account, by removing guest from loopback_users, but it's recommended to create a new user to follow best practices.
