Winows上简单配置使用kafka(.net使用)
一、kafka环境配置
1.jdk安装
安装文件:http://www.oracle.com/technetwork/java/javase/downloads/index.html 下载JDK
安装完成后需要添加以下的环境变量(右键点击“我的电脑” -> "高级系统设置" -> "环境变量" ):
JAVA_HOME: C:\Program Files\Java\jdk-13.0.1(jdk的安装路径)
Path: 现有值后追加 "%JAVA_HOME%\bin"
2.zookeeper安装
Kafka的运行依赖于Zookeeper,所以在运行Kafka之前我们需要安装并运行Zookeeper
下载安装文件: http://zookeeper.apache.org/releases.html
解压文件 apache-zookeeper-3.5.6-bin.tar
ZOOKEEPER_HOME: C:\Users\Yc\work\apache-zookeeper-3.5.6 (zookeeper目录)
Path: 在现有的值后面添加 ";%ZOOKEEPER_HOME%\bin;"
运行Zookeeper: 打开cmd然后执行 zkserver
3.安装并运行kafka
4.创建Topics
cmd执行命令:cd C:\Users\Yc\work\kafka_2.12-2.3.0\bin\windows
kafka-topics.bat --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test
执行成功后出现 :Created topic test
5.生产者使用测试
打开cmd窗口执行命令:cd C:\Users\Yc\work\kafka_2.12-2.3.0\bin\windows
kafka-console-producer.bat --broker-list localhost:9092 --topic test
6.消费者使用测试
打开cmd窗口执行命令:cd C:\Users\Yc\work\kafka_2.12-2.3.0\bin\windows
kafka-console-consumer.bat --bootstrap-server localhost:9092 --topic test --from-beginning
7..net程序消费者简单使用
引入Confluent.kafka包
public static void Main(string[] args) { //地址及端口号 var conf = new ProducerConfig { BootstrapServers = "localhost:9092" }; Action<DeliveryReport<Null, string>> handler = r => Console.WriteLine(!r.Error.IsError ? $"Delivered message to {r.TopicPartitionOffset}" : $"Delivery Error: {r.Error.Reason}"); using (var p = new ProducerBuilder<Null, string>(conf).Build()) { //for (int i = 0; i < 100; ++i) //{ p.Produce("test", new Message<Null, string> { Value = "messagehowsf"}, handler);//kafka协议数据发送 //} // wait for up to 10 seconds for any inflight messages to be delivered. p.Flush(TimeSpan.FromSeconds(10)); } }
