MQTT无法连接到Apollo服务器

从官方网站下载Apollo并安装在Mac OS X 10.10.2中，如主题所述Apollo 1.7 MQTT Protocol Manual，我在apache-apollo-1.7 / bin / androidMQ / etc / apollo.xml中为mqtt设置了连接器：

<connector id="tcp" bind="tcp://0.0.0.0:61613" protocol="mqtt"/>

然后创建一个代理（androidMQ）并运行：

androidMQ/bin/apollo-broker run

这样的日志：

$ androidMQ/bin/apollo-broker run

然后，我用它与ruby gem：ruby-mqtt，我的脚本是：

subsctibe.rb

require 'rubygems'
require 'mqtt'
MQTT::Client.connect("localhost", 1883) do |client|
  client.get("test") do |topic, message|
    puts "#{topic}---content: #{message}\n"
  end
end

publish.rb

require 'rubygems'
require 'mqtt'
MQTT::Client.connect("localhost", 1883) do |c|
  c.publish("test", "gogogo!")
end

当我运行它时，错误：

$ ruby lib/mqtt/apollo_subscribe.rb
/Users/jijin/.rvm/gems/ruby-1.9.3-p547/gems/mqtt-0.3.1/lib/mqtt/client.rb:496:in `block in receive_connack': Connection refused: bad user name or password (MQTT::ProtocolException)

    from lib/mqtt/apollo_subscribe.rb:4:in `'

当我将主机和端口更改为：

MQTT::Client.connect("test.mosquitto.org", 1883)

测试没问题，但是当我将主机更改为localhost时，无论我将端口更改为1883或61613，都会发生错误 . 我现在不知道该怎么办 .
