kafka 安装与配置

下载

地址:https://kafka.apache.org/downloads

这里下载的是kafka_2.11-0.11.0.1.tgz

解压

tar -xzf kafka_2.11-0.11.0.1.tgz
cd kafka_2.11-0.11.0.1

启动zookeeper

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

默认使用的2181端口,可在配置文件修改。

启动kafka server

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

(非本地生产者和消费者访问Kafka,记得修改 config/server.properties中的listeners, 例如
listeners=PLAINTEXT://192.168.33.152:9092)

create a topic

bin/kafka-topics.sh –create –zookeeper localhost:2181 –replication-factor 1 –partitions 1 –topic test

查看topic

bin/kafka-topics.sh –list –zookeeper localhost:2181

好像没有输出

启动生产者

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

输入

This is a message
This is another message

启动消费者

$ bin/kafka-console-consumer.sh –bootstrap-server localhost:9092 –topic test –from-beginning
This is a message
This is another message

如果无法启动,根据提示,可能需要加zookeeper:

$ bin/kafka-console-consumer.sh –bootstrap-server localhost:9092 –zookeeper localhost:2181 –topic test –from-beginning
