1.docker 安装kafka一直无法测试生产者生产消息成功

docker安装完kafka之后，创建topic没有报错
bash-4.4# kafka-topics.sh --create --zookeeper 118.190.26.133:2181 --replication-factor 1 --partitions 1 --topic mytest_topic
WARNING: Due to limitations in metric names, topics with a period ('.') or underscore ('_') could collide. To avoid issues it is best to use either, but not both.
Created topic mytest_topic.

但是运行生产者时候出现了一下错误
bash-4.4# kafka-console-producer.sh --broker-list 118.190.26.133:9092 --topic mytest_topic

############################# Server Basics #############################

The id of the broker. This must be set to a unique integer for each broker.

broker.id=0
advertised.host.name=master
############################# Socket Server Settings #############################

The address the socket server listens on. It will get the value returned from

java.net.InetAddress.getCanonicalHostName() if not configured.

FORMAT:

listeners = listener_name://host_name:port

EXAMPLE:

listeners = PLAINTEXT://your.host.name:9092

listeners=PLAINTEXT://0.0.0.0:9092

Hostname and port the broker will advertise to producers and consumers. If not set,

it uses the value for "listeners" if configured. Otherwise, it will use the value

returned from java.net.InetAddress.getCanonicalHostName().

advertised.listeners=PLAINTEXT://118.190.26.133:9092
