Kafka在windows下的配置使用
Kafka是最初由Linkedin公司开发,是一个分布式、支持分区的(partition)、多副本的(replica),基于zookeeper协调的分布式消息系统,它的最大的特性就是可以实时的处理大量数据以满足各种需求场景:比如基于hadoop的批处理系统、低延迟的实时系统、storm/Spark流式处理引擎,web/nginx日志、访问日志,消息服务等等,用scala语言编写,Linkedin于2010年贡献给了Apache基金会并成为顶级开源 项目。具体理论性的内容我也不是特别懂,这里有一篇文章写的很好,转发一下https://blog.csdn.net/YChenFeng/article/details/74980531
下面就开始配置和使用
1、下载
下载地址:http://kafka.apache.org/downloads.html ,我用的是kafka_2.12-1.0.0.tgz版本。有兴趣的可以下载最新办法。
2、下载完成之后,直接解压,目录结构是这样的
bin目录是各种启动文件,config是相关参数配置文件,logs是自建的日志文件,libs是使用到的相关jar文件
启动文件中有windows项,用例直接启动相关服务。
3、修改配置参数
进入config目录,编辑 server.properties文件,找到并编辑log.dirs= D:\\Tools\\kafka_2.11-1.0.0\\logs,找到并编辑zookeeper.connect=localhost:2181。表示本地运行。
(Kafka会按照默认,在9092端口上运行,并连接zookeeper的默认端口:2181)
4、启动服务,在dos服务下输入下面命令进行启动
D:\tools\kafka_2.12-2.1.0\bin\windows\zookeeper-server-start.bat D:\tools\kafka_2.12-2.1.0\config\zookeeper.properties
首先启动,zookeeper服务,对应加载zookeeper的配置文件,kafka依赖zookeeper监控其状态
D:\tools\kafka_2.12-2.1.0\bin\windows\kafka-server-start.bat D:\tools\kafka_2.12-2.1.0\config\server.properties
然后启动kafka服务,对应加载相应配置文件
5、使用idea在git 上下载kafka-monitor 代码,地址:https://github.com/linxin26/kafka-monitor
运行Start,在浏览器输入http://127.0.0.1:5050
查看现有主题 topic
查看 broker
6、编写测试类查看相关状况
import org.apache.kafka.clients.consumer.ConsumerRebalanceListener; import org.apache.kafka.clients.consumer.ConsumerRecord; import org.apache.kafka.clients.consumer.ConsumerRecords; import org.apache.kafka.clients.consumer.KafkaConsumer; import org.apache.kafka.common.TopicPartition; import java.util.Arrays; import java.util.Collection; import java.util.Properties; /** * Created by songxiaofei on 2018-12-27. */ public class ConsumerMessage { public static void main(String[] args){ Properties props = new Properties(); props.put("bootstrap.servers", "10.1.9.3:9092"); props.put("group.id", "test"); props.put("enable.auto.commit", "true"); props.put("auto.commit.interval.ms", "1000"); props.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer"); props.put("value.deserializer", "org.apache.kafka.common.serialization.StringDeserializer"); final KafkaConsumer<String, String> consumer = new KafkaConsumer<String,String>(props); consumer.subscribe(Arrays.asList("buy"),new ConsumerRebalanceListener() { public void onPartitionsRevoked(Collection<TopicPartition> collection) { } public void onPartitionsAssigned(Collection<TopicPartition> collection) { //将偏移设置到最开始 consumer.seekToBeginning(collection); } }); while (true) { ConsumerRecords<String, String> records = consumer.poll(100); for (ConsumerRecord<String, String> record : records) System.out.printf("offset = %d, key = %s, value = %s%n,checksum=%s", record.offset(), record.key(), record.value(),record.checksum()); } } }
执行代码,可以查看相关日志,用来查看kafka的配置情况

7、使用命令行创建topic
D:\tools\kafka_2.12-2.1.0\bin\windows\kafka-topics.bat --create --zookeeper localhost:12181 --replication-factor 1 --partitions 1 --topic hello
查看已有的topic
D:\tools\kafka_2.12-2.1.0\bin\windows\kafka-topics.bat --list --zookeeper 127.0.0.1:12181
创建一个消息生产者,同时创建一个消息消费者,去接收消息生产者发来的消息
D:\tools\kafka_2.12-2.1.0\bin\windows\kafka-console-producer.bat --broker-list 127.0.0.1:9092 --topic hello 创建一个消息生产者
D:\tools\kafka_2.12-2.1.0\bin\windows\kafka-console-consumer.bat --bootstrap-server 127.0.0.1:9092 --topic hello --from-beginning 创建一个消息消费者
