kafka listeners 和 advertised.listeners配置内外网都可用_kafka advertised.listeners配置内网和nginx代理的地址

内网访问

在内网部署及访问kafka时，只需要配置listeners参数即可，比如

# 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://192.168.133.11:9092

# 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://your.host.name:9092

按照官网的参数说明，此时advertised.listeners默认值等于listeners参数的值，并被发布到zooleeper中，供客户端访问使用。此时kafka服务、broker之间通信都是使用192.168.133.11:9092<
