我创建了一个vagrant/ansible playbook来构建一个单节点kafka vm。
我们的想法是在原型设计时提供一些灵活性：如果我们想要一个快速而肮脏的kafka消息队列，我们可以 git clone [my 'kafka in a box' repo] , cd .. 以及 vagrant up .
以下是我迄今为止所做的：
流浪汉档案：

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  config.vm.box = "hashicorp/precise64"

  config.vm.network "forwarded_port", guest:9092, host: 9092

  config.vm.provider "virtualbox" do |vb|
    vb.customize ["modifyvm", :id, "--memory", "2048"]
  end

  config.vm.provision "ansible" do |ansible|
    ansible.playbook = "kafkaPlaybook.yml"
  end

end

... 还有ansible kafkaPlaybook.yml 文件：

---
- hosts: all
  user: vagrant
  sudo: True

  tasks:

    - name: install linux packages
      action: apt update_cache=yes pkg={{item}} state=installed
      with_items:
        - vim
        - openjdk-7-jdk

    - name: make /usr/local/kafka directory
      shell: "mkdir /usr/local/kafka"

    - name: download kafka (the link is from an apache mirror)
      get_url: url=http://apache.spinellicreations.com/kafka/0.8.1.1/kafka-0.8.1.1-src.tgz dest=/usr/local/kafka/kafka-0.8.1.1-src.tgz mode=0440

    - name: untar file
      shell: "tar -xvf /usr/local/kafka/kafka-0.8.1.1-src.tgz -C /usr/local/kafka"

    - name: build kafka with gradle
      shell: "cd /usr/local/kafka/kafka-0.8.1.1-src && ./gradlew jar"

当我 vagrant up 这个盒子已经准备好了。我可以 vagrant ssh 并在本地执行基本的生产者/消费者测试，例如。

cd /usr/local/kafka/kafka-0.8.1.1-src
bin/zookeeper-server-start.sh config/zookeeper.properties                               #start zookeeper
bin/kafka-server-start.sh config/server.properties                                      #start kafka
bin/kafka-console-producer.sh --broker-list localhost:9092 --topic tests                #start a producer
bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic test --from-beginning  #start a consumer

当我在producer窗口中键入消息时，它们会出现在consumer窗口中。伟大的。
我尝试使用kafka python包从主机连接到kafka：

>>> from kafka import KafkaClient, SimpleProducer
>>> kafka = KafkaClient("127.0.0.1:9092", timeout=120)
>>> kafka.ensure_topic_exists('turkey')
No handlers could be found for logger "kafka"
>>> kafka.ensure_topic_exists('turkey')
>>> producer = SimpleProducer(kafka)
>>> producer.send_messages("turkey", "gobble gobble")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/awoolford/anaconda/lib/python2.7/site-packages/kafka/producer.py", line 261, in send_messages
    return super(SimpleProducer, self).send_messages(topic, partition, *msg)
  File "/Users/awoolford/anaconda/lib/python2.7/site-packages/kafka/producer.py", line 188, in send_messages
timeout=self.ack_timeout)
  File "/Users/awoolford/anaconda/lib/python2.7/site-packages/kafka/client.py", line 312, in send_produce_request
    resps = self._send_broker_aware_request(payloads, encoder, decoder)
  File "/Users/awoolford/anaconda/lib/python2.7/site-packages/kafka/client.py", line 148, in _send_broker_aware_request
    conn = self._get_conn(broker.host, broker.port)
  File "/Users/awoolford/anaconda/lib/python2.7/site-packages/kafka/client.py", line 55, in _get_conn
    timeout=self.timeout
  File "/Users/awoolford/anaconda/lib/python2.7/site-packages/kafka/conn.py", line 60, in __init__
self.reinit()
  File "/Users/awoolford/anaconda/lib/python2.7/site-packages/kafka/conn.py", line 195, in reinit
self._raise_connection_error()
  File "/Users/awoolford/anaconda/lib/python2.7/site-packages/kafka/conn.py", line 75, in _raise_connection_error
    raise ConnectionError("Kafka @ {0}:{1} went away".format(self.host, self.port))
kafka.common.ConnectionError: Kafka @ precise64:9092 went away

这个 kafka.ensure_topic_exists 打了两次电话。第一次运行时，它会返回一个警告，然后创建主题，这样我就可以看到python正在端口9092上与kafka通信。但是，我无法向队列发送消息。
你能看出我做错了什么吗？
