kafka单节点测试

======================命令======================

启动zookeeper server

bin/zookeeper-server-start.sh config/zookeeper.properties &

&是为了能退出命令行

启动kafka server

bin/kafka-server-start.sh config/server.properties &

停止kafka server

bin/kafka-server-stop.sh

停止zookeeper server

bin/zookeeper-server-stop.sh

======================单broker测试======================

运行producer

bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test

早版本的Kafka，--broker-list localhost:9092需改为--zookeeper localhost:2181

运行consumer

bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic test --from-beginning

在producer端输入字符串并回车，查看consumer端是否显示。
