zookeeper.properties修改dataDir

dataDir=G:\zookeeper-3.5.5\data
# the port at which the clients will connect
clientPort=2181
# disable the per-ip limit on the number of connections since this is a non-production config
maxClientCnxns=0

server.properties修改log.dirs

############################# Log Basics #############################

# A comma separated list of directories under which to store log files
log.dirs=G:\kafka\logs

 

运行zookeeper命令

zkserver

 

进入cd G:\kafka\bin\windows

 

启动服务：

kafka-server-start.bat ../../config/server.properties

创建实例

kafka-topics.bat --create --zookeeper localhost:2181 --repl
ication-factor 1 --partitions 1 --topic testDemo

 

生产者

kafka-console-producer.bat --broker-list localhost:9092 --t
opic testDemo

 

 

消费者

kafka-console-consumer.bat --bootstrap-server localhost:909
2 --topic testDemo --from-beginning

 

在生产者里输入内容，消费者就打印出相应内容
