我在私有网络的10.242.44.55上有一台装有Zookeeper和Kafka的集群。我把网关上的端口从[public_ip]:39092转发到10.242.44.55:9092。
listeners=INTERNAL://:9092,EXTERNAL://:39092
advertised.listeners=INTERNAL://10.242.44.55:9092,EXTERNAL://[public_ip]:39092
listener.security.protocol.map=INTERNAL:PLAINTEXT,EXTERNAL:PLAINTEXT
inter.broker.listener.name=INTERNAL
在私有网络中一切工作正常。我可以从不同的电脑上生产和消费信息。不幸的是，当我试图从外面生产消息时，返回了一个错误。
pers@pc:/opt/kafka$ bin/kafka-console-producer.sh —broker-list [public_ip]:39092 —topic test
>testMessage
>[2018-03-24 17:51:04,393] ERROR Error when sending message to topic test with key: null, value: 11 bytes with error: (org.apache.kafka.clients.producer.internals.ErrorLoggingCallback)

[2018-03-24 17:53:13,970] WARN [Producer clientId=console-producer] Connection to node 0 could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient)
但是，我用telnet是可以通的。
pers@pc:/opt/kafka$ telnet [public_ip] 39092
Trying [public_ip]...
Connected to [public_ip].
Escape character is '^]'.
test
Connection closed by foreign host.
有该怎么办呢？
broker配置的一部分：
listeners=EXTERNAL://:39092,INTERNAL://:9092 advertised.listeners=EXTERNAL://77.1.1.1:39092,INTERNAL://10.1.1.1:9092 listener.security.protocol.map=EXTERNAL:PLAINTEXT,INTERNAL:PLAINTEXT inter.broker.listener.name=INTERNAL你可以试试看。
