kafka安装
jdk、kafka版本如下，zookeeper使用kafka自带版本
安装包下载位置:https://download.csdn.net/download/henreash/90087368 (赚点csdn下载资源分)
安装jdk后，解压kafka压缩包，修改配置文件：
kafka_2.13-3.9.0\config\zookeeper.properties内修改：dataDir=D:/Kafka/zookeeper/data
kafka_2.13-3.9.0\config\server.properties内修改：log.dirs=D:/Kafka/kafka-logs
在目录内创建批处理文件，启动zookeeper和kafka：
kfk.cmd内容：call bin/windows/kafka-server-start.bat config/server.properties
zk.bat内容：call bin/windows/zookeeper-server-start.bat config/zookeeper.properties
双击zk.bat、kfk.cmd启动zookeeper和kafka
kafka-manager安装
将kafka-manager2解压到d盘，注意目录结构不能太深，否则启动报错。
修改config\application.conf，修改节点kafka-manager.zkhosts指向zookeeper
kafka-manager.zkhosts="192.168.0.109:2181"
创建start.bat批处理文件，内容：.\bin\kafka-manager.bat
双击启动kafka-manager。
打开浏览器，输入地址：http://localhost:9000/
点击Cluster菜单，创建一个默认Cluster Test001；
kafka环境配置完毕。
C#调用
创建C#8项目，在nuget中下载Confluent.Kafka(2.6.1),如下代码进行消息发布和订阅。
private async void simpleButton2_Click(object sender, EventArgs e){var config = new ProducerConfig { BootstrapServers = "localhost:9092"};using (var producer = new ProducerBuilder<Null, string>(config).Build()){var dr = await producer.ProduceAsync("test-topic", new Message<Null, string> { Value = "hello,world" });Debug.WriteLine($"Delivered '{dr.Value}' to '{dr.TopicPartitionOffset}'");}}private void simpleButton3_Click(object sender, EventArgs e){Task.Factory.StartNew(() => {var config = new ConsumerConfig{GroupId = "test-consumer-group",BootstrapServers = "localhost:9092",AutoOffsetReset = AutoOffsetReset.Earliest};var cts = new CancellationTokenSource();using (var consumer = new ConsumerBuilder<Ignore, string>(config).Build()){consumer.Subscribe("test-topic");try{while (true){try{var cr = consumer.Consume(cts.Token);Debug.WriteLine($"Consumed message '{cr.Value}' at: '{cr.TopicPartitionOffset}'.");}catch (Exception ex){Console.WriteLine(ex);}}}catch (Exception ex2){Console.WriteLine(ex2);}}});}执行后kafka-manager界面如下图：
