kafka listeners和advertised配置
kafka listeners和advertised配置
kafka版本:kafka_2.11-2.3.0
kafka配置listeners
# 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
kafka配置advertised
# 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
listeners
listeners
就是主要用来定义Kafka Broker的Listener的配置项。
advertised.listeners
advertised.listeners
参数的作用就是将Broker的Listener信息发布到Zookeeper中
下面演示现象:
第一种情况:
默认都不配置
zookeeper查看kafka地址:
kafka创建topic
添加主机hosts访问正常
192.168.11.103 xuliang-PC
第二种情况
配置 listeners=PLAINTEXT://192.168.11.103:9092
默认advertised.listeners也是 192.168.11.103:9092
此时访问要通过:bin/kafka-topics.sh --list --bootstrap-server 192.168.11.103:9092
第三种情况:
配置如下:
第四种情况:
配置如下:
监听地址:
内外网分流:
listener.security.protocol.map=EXTERNAL:PLAINTEXT,INTERNAL:PLAINTEXT listeners=EXTERNAL://192.168.11.103:9092,INTERNAL://192.168.11.103:9093 inter.broker.listener.name=INTERNAL #advertised.listeners=EXTERNAL://192.168.11.103:9094,INTERNAL://192.168.11.103:9093
[zk: localhost:2181(CONNECTED) 8] get /brokers/ids/0 {"listener_security_protocol_map":{"EXTERNAL":"PLAINTEXT","INTERNAL":"PLAINTEXT"},"endpoints":["EXTERNAL://192.168.11.103:9092","INTERNAL://192.168.11.103:9093"],"jmx_port":-1,"host":"192.168.11.103","timestamp":"1573920483772","port":9092,"version":4}
内网访问可以使用:192.168.11.103:9093
外网访问使用:192.168.11.103:9092
这在kafka部署到kubernetes时候就很有用了
listeners
listeners
就是主要用来定义Kafka Broker的Listener的配置项。
advertised.listeners
advertised.listeners
参数的作用就是将Broker的Listener信息发布到Zookeeper中
inter.broker.listener.name
inter.broker.listener.name:专门用于Kafka集群中Broker之间的通信
listener.security.protocol.map
配置监听者的安全协议的,比如PLAINTEXT
、SSL
、SASL_PLAINTEXT
、SASL_SSL
新版本kafka product 和consumer访问集群方式:
xuliang@xuliang:/usr/local/kafka_2.11-2.3.0$ bin/kafka-console-producer.sh --broker-list 192.168.11.103:9092 --topic test >this is a test xuliang@xuliang:/usr/local/kafka_2.11-2.3.0$ 0$ bin/kafka-consoconsumer.sh --bootstrap-server 192.168.11.103:9092 --from-beginning --topic test this is a test this is a test
总结:
listeners
是kafka真正bind的地址
advertised.listeners
是暴露给外部的listeners,如果没有设置,会用listeners
