Kafka Startup

Installation

Please refer to https://kafka.apache.org/quickstart.

Configurations

One important thing is to change the advertised.listeners in ${KAFKA_HOME}/config/server.properties, like,

# 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://\<IP or hostname>:9092

Otherwise, any clients, like java, will not poll any messages from the server.
