kafka listeners和advertised配置

kafka  listeners和advertised配置

kafka版本:kafka_2.11-2.3.0java

kafka配置listenersbootstrap

# 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安全

# 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就是主要用來定義Kafka Broker的Listener的配置項。socket

advertised.listeners

advertised.listeners參數的做用就是將Broker的Listener信息發佈到Zookeeper中this

 

下面演示現象:

第一種狀況:

默認都不配置spa

zookeeper查看kafka地址:

 

kafka建立topic

 

 

 

 

 添加主機hosts訪問正常

192.168.11.103 xuliang-PC.net

 

 第二種狀況

配置 listeners=PLAINTEXT://192.168.11.103:9092code

默認advertised.listeners也是 192.168.11.103:9092server

 

 此時訪問要經過:bin/kafka-topics.sh --list --bootstrap-server 192.168.11.103:9092blog

第三種狀況:

配置以下:

 

 

 

第四種狀況:

配置以下:

 

 

 

 監聽地址:

 

 內外網分流:

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}

 內網訪問能夠使用:192.168.11.103:9093

外網訪問使用:192.168.11.103:9092

這在kafka部署到kubernetes時候就頗有用了

 

listeners

listeners就是主要用來定義Kafka Broker的Listener的配置項。

advertised.listeners

advertised.listeners參數的做用就是將Broker的Listener信息發佈到Zookeeper中

inter.broker.listener.name

inter.broker.listener.name:專門用於Kafka集羣中Broker之間的通訊

listener.security.protocol.map

配置監聽者的安全協議的,好比PLAINTEXTSSLSASL_PLAINTEXTSASL_SSL

新版本kafka product 和consumer訪問集羣方式:

 

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

 

總結:

 

listeners

是kafka真正bind的地址

 

advertised.listeners

是暴露給外部的listeners,若是沒有設置,會用listeners
