Question

我在Ubuntu 14.04上安装了RabbitMQ 3.6.9，我想用pika制作一个基本的生产者 - 消费者示例，但与RabbitMQ网站上的教程不同，我喜欢消费者要在另一台机器上。

我知道我可以将[{rabbit, [{loopback_users, []}]}].添加到rabbitmq.config并避免所有身份验证问题，但我想在我的示例中包含连接的身份验证方面。

我首先添加了一个新用户：rabbitmqctl add_user user password，然后运行了以下脚本：

import pika

url = '10.0.0.1'

credentials = pika.PlainCredentials('user', 'password')
parameters = pika.ConnectionParameters(host=url, credentials=credentials)
connection = pika.BlockingConnection(parameters)
connection.close()
print 'Made it through!'

但是，我得到以下例外：

Traceback (most recent call last):
  File "test.py", line 8, in <module>
    connection = pika.BlockingConnection(parameters)
  File "/usr/local/lib/python2.7/dist-packages/pika/adapters/blocking_connection.py", line 339, in __init__
    self._process_io_for_connection_setup()

    return self._handle_error(error)
  File "/usr/local/lib/python2.7/dist-packages/pika/adapters/base_connection.py", line 338, in _handle_error
    self._handle_disconnect()
  File "/usr/local/lib/python2.7/dist-packages/pika/adapters/base_connection.py", line 288, in _handle_disconnect
    self._adapter_disconnect()
  File "/usr/local/lib/python2.7/dist-packages/pika/adapters/select_connection.py", line 95, in _adapter_disconnect
    super(SelectConnection, self)._adapter_disconnect()
  File "/usr/local/lib/python2.7/dist-packages/pika/adapters/base_connection.py", line 154, in _adapter_disconnect
    self._check_state_on_disconnect()
  File "/usr/local/lib/python2.7/dist-packages/pika/adapters/base_connection.py", line 178, in _check_state_on_disconnect
    raise exceptions.ProbableAccessDeniedError
pika.exceptions.ProbableAccessDeniedError

根据pika的消息来源，这意味着：＆＃34;客户端在连接阶段断开连接，表明可能拒绝访问指定的虚拟主机＆＃34;，所以我想也许我应该添加一个虚拟主机而不是使用默认值，所以我运行rabbitmqctl add_vhost testvhost，重新启动服务器，并运行以下脚本：

import pika

url = '10.0.0.1'
vhost = 'testhvost'

credentials = pika.PlainCredentials('user', 'password')
parameters = pika.ConnectionParameters(host=url, virtual_host=vhost, credentials=credentials)
connection = pika.BlockingConnection(parameters)
connection.close()
print 'Made it through!'

但是我仍然得到同样的例外。

我错过了什么？在我能让它工作之前，我需要有任何基本的rabbitmq.config文件吗？服务器是一个干净的安装，因此目前没有加载配置文件。

您是否向该用户添加了访问虚拟主机的权限？

到默认虚拟主机：

rabbitmqctl set_permissions user ".*" ".*" ".*"

到你新创建的：

rabbitmqctl set_permissions -p /testhvost user ".*" ".*" ".*"

无法让远程用户使用RabbitMQ成功进行身份验证
