kafka VirtualBox windows linux

windows宿主机消费Linux虚拟机kafka集群报异常WARN Connection to node 0 could not be established. Broker may not be available

配置如下：

1、Linux
kafka_2.11-0.11.0.2 集群三台机子分别配置：

server.properties配置

advertised.listeners=PLAINTEXT://10.0.2.5:9092
advertised.listeners=PLAINTEXT://10.0.2.6:9092
advertised.listeners=PLAINTEXT://10.0.2.7:9092

2、Linux hosts配置

10.0.2.5   hadoop01.richstone.com

3、Linux nginx配置

stream {
         upstream brokers {
               server 10.0.2.5:9092 weight=1;
               server 10.0.2.6:9092 weight=1;
               server 10.0.2.7:9092 weight=1;
         }

        server {
               listen 18001;
               proxy_pass brokers;
         }
}

4、虚拟机nat端口转发
10.0.2.5:18001 转发到宿主机127.0.0.1:18001

5、windows宿主机配置hosts配置
127.0.0.1 hadoop01.richstone.com

6、测试windows宿主机：
Telnet 127.0.0.1:18001 可以ping通

7、windows消费数据：

.\bin\windows\kafka-console-consumer.bat --topic first --bootstrap-server hadoop01.richstone.com:18001 --from-beginning

但是上面消费数据的时候报异常

WARN Connection to node 0 could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient)
