python - 尝试按照 celery 教程进行操作时，RabbitMQ 会出现 "access refused, login refused for user"错误

Question

我正在尝试关注 celery tutorial ，但是当我运行 python manage.py celeryd 时遇到了一个问题:我的 RabbitMQ 服务器(安装在我开发箱的虚拟机上)不允许我的用户登录。

我在我的 Django 管理控制台上得到以下信息:

[ERROR/MainProcess] AMQP Listener: Connection Error: Socket closed. Trying again in 2 seconds...

这显示在我的 RabbitMQ 服务器上的 rabbit.log 文件中:

exception on TCP connection <0.5814.0> from $DJANGO_BOX_IP
{channel0_error,starting,{amqp,access_refused,"login refused for user '$CONFIGURED_USER'",'connection.start_ok'}}

我仔细检查了我的用户、权限和虚拟主机信息，它们似乎都匹配。非常感谢任何帮助故障排除。

更新:按照@asksol 的建议，我得到以下回溯:

IOError: Socket closed

Answer 1

你在运行 django 吗？如果是这样，那么试试这个:

>>> from carrot.connection import DjangoBrokerConnection
>>> c = DjangoBrokerConnection()
>>> c.connection

它给出同样的东西吗？您确定您正在连接到正确的主机名，并且用户名和密码可以访问虚拟主机吗？

更新:

>>> from carrot.connection import DjangoBrokerConnection
>>> c = DjangoBrokerConnection()
>>> for n in ("host", "userid", "password", "virtual_host", "ssl"):
...     print("%s -> %s" % (n, repr(getattr(c, n, None))))

更新:您必须在运行 c.connection 之前执行上述操作，因为连接是在 carrot 中延迟建立的。
