Kafka 集群允许外部访问配置

今天搭建新的kafka 集群给大数据和中台部门共用，搭建好了，内部访问测试是可以的，外部其他机器访问不通，查了下，原来是有个外部访问的参数没有配置。配置 listeners，如下

看了下示例，conf文件里面是有说明的

############################# 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://: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

 配置好listeners后，重启集群，访问成功。
