kafka集群搭建（windows环境)

Apache Downloads 下载zk 

 

 准备三份

 

 每个zk都创建这两个文件夹

 

 在每个zkData都创建myid文件，没有后缀名

内容分别写着 1   2  3 (zk3.8-1  写的1，3.8-2写的2 ，类推)

将conf中刚下载的文件改成zoo.cfg

 

 

myid的数字和server.x对应 ， 除了clientPort修改为2081,2082,2083之外别的照抄，由于是一个电脑操作，只能改端口不改ip

 

 进入bin启动zkServer.cmd

启动报错

 

 

 修改zkEnv的java的home

 

 如果还是找不到，建议把java的jdk复制一份放在别的盘符

 

 都启动成功后

 Apache Kafka 下载kafka

报错：

D:\kafka\kafka1\bin\windows>kafka-server-start.bat ../../config/server.properties
Error: missing `server' JVM at `C:\Program Files (x86)\Java\jre1.8.0_131\bin\server\jvm.dll'.
Please install or use the JRE or JDK that contains these missing components.

 

 

搜到jvm.dll，复制到当前文件夹

 

 

 

继续启动，报错

Unrecognized VM option 'UseCompressedOops'
Did you mean '(+/-)CheckCompressedOops'?
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

 

删除这个:kafka-run-class.bat文件中

 

 

 

启动第一个没问题，启动第二个第三个报错。

把config的/server.properties

然后在外面创建文件夹

 

 

 正常启动成功

 

测试集群

（1）创建一个 topic

kafka-topics.bat --create --zookeeper 127.0.0.1:2181 --replication-factor 1 --partitions 1 --topic test

 

（2）查看是否创建成功

kafka-topics.bat --list --zookeeper localhost:2181

 

（3）发送消息

kafka-console-producer.bat --broker-list localhost:9092 --topic test

This is a message

 

（4）接收消息

kafka-console-consumer.bat --zookeeper localhost:2181 --topic test --from-beginning 

 

不同客户端能接收到消息，说明配置成功
