我是新来Kafka和搜索不同的职位在论坛上，但找不到解决办法。我已经在一个ec2示例上安装了kafka，并试图从我的ubuntu本地机器上连接它。我的目标是让python-kafka客户机（生产者和消费者）在我的本地机器上运行，并通过ec2-kafka示例发送/接收数据。有可能吗？
在server.properties配置文件中设置的属性：

listeners=PLAINTEXT://0.0.0.0:9092 
advertised.listeners=PLAINTEXT://<ec2-public-DNS>:9092

Kafkaec2示例：

netstat -an | grep LISTEN 
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 
tcp6 0 0 :::9092 :::* LISTEN

在kafka ec2示例上的zookeeper cli上：

get /brokers/ids/0
{"listener_security_protocol_map":{"PLAINTEXT":"PLAINTEXT"},"endpoints":["PLAINTEXT://<ec2-public-DNS>:9092"],"jmx_port":-1,"host":"<ec2-public-DNS>","timestamp":"1492900361516","port":9092,"version":4}
cZxid = 0xed
ctime = Sat Apr 22 22:32:41 UTC 2017
mZxid = 0xed
mtime = Sat Apr 22 22:32:41 UTC 2017
pZxid = 0xed
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x15b97cb9d060000
dataLength = 250
numChildren = 0

本地计算机上的python客户端（生产者）：

from kafka import KafkaProducer
import time
import json

producer = KafkaProducer(bootstrap_servers="<ec2-public-DNS>:9092")
for i in range(100):
    dict = {}
    dict['name_'+str(i)] = 'FILE_' + str(i)
    dict['size_'+str(i)] = '23.' + str(i)
    dict['host_'+str(i)] = '10.0.0.0' + str(i)
    jd = json.dumps(dict)
    producer.send('console-test-topic', jd)
    time.sleep(2)

本地计算机上的python客户端（使用者）：

from kafka import KafkaConsumer

consumer = KafkaConsumer('console-test-topic', bootstrap_servers="<ec2-public-DNS>:9092")
for msg in consumer:
    print (msg)

但是，生产者无法连接到kafka ec2示例，失败，错误如下：

**kafka.errors.NoBrokersAvailable: NoBrokersAvailable**

请参阅我的安全组规则的链接：

我尝试在另一个ec2示例（与kafka示例在同一个vpn中）中运行producer client，效果很好。但是，当producer在我的本地机器上运行时，它就不工作了。“adverted.listeners”属性是否在同一个（awsvpn）网络中为kafka代理做广告？或者我也可以从我的本地机器连接它？如果有人能给我指出正确的方向，请告诉我。
