RabbitMQ 3.5.6无法建立到任何已配置主机的TCP连接(Bunny::TCPConnectionFailedForAllHosts)

Question

我正在尝试连接到RabbitMQ服务器，但总是收到以下错误：

W, [2015-12-08T15:38:01.993251 #37405]  WARN -- #<Bunny::Session:0x7fe07b894f78 guest@localhost:5672, vhost=/dev_prod, addresses=[localhost:5672]>: An empty frame was received while opening the connection. In RabbitMQ <= 3.1 this could mean an authentication issue.

和

.../.rvm/gems/ruby-2.1.2/gems/bunny-2.2.0/lib/bunny/session.rb:315:in `rescue in start': Could not establish TCP connection to any of the configured hosts (Bunny::TCPConnectionFailedForAllHosts)

我在MAC上使用的是Ruby2.1.2，RabbitMQ 3.5.6。对不起，我是RabbitMQ的新手，只是想用它，但无法处理这个问题。请给我一些建议。

这可能是因为您没有传递用户名和密码，或者传递了错误的用户名和密码。

用户名和密码的默认值均为guest和guest。

尝试像这样初始化连接：

 conn = Bunny.new(host:  'localhost',
                  port:  '5672',
                  vhost: '/',
                  user:  'guest',
                  pass:  'guest')
 conn.start

看看会发生什么
