kafka+java 伪分布式安装和配置

来源：互联网发布：ipad三维建模软件编辑：程序博客网时间：2024/05/20 16:40

最近在研究kafka先从简单的入手下面是官网资料

官网：http://kafka.apache.org/

官方文档：http://kafka.apache.org/documentation.html#quickstart

第一步官网下载 kafka_2.11-0.9.0.1.tgz

解压：

# tar xzf kafka_2.9.2-0.8.1.1.tgz# cd kafka_2.9.2-0.8.1.1

第二步配置环境变量

  # vi /etc/profile   export KAFKA_HOME=/home/grid/kafka_2.11-0.9.0.1  export PATH=$PATH:/home/grid/kafka_2.11-0.9.0.1/bin

第三步配置文件server.properties 主要参数

 broker.id=69 host.name=192.168.170.69 advertised.host.name=192.168.170.69 num.partitions=2 log.dirs=/home/temp/zookeeper/kafka-logs zookeeper.connect=192.168.170.69:2181

zookeeper.connect这里zookeeper 是单机的当然自己可以搭建集群 zookeeper.connect=192.168.170.69:2181 后加逗号分隔

第四步启动服务之前确保zookeeper 服务是启动的

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

启动后的日志

以上表示启动成功

第五步

创建topic

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

列出topic

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

test

producer
# Send some messages （发送一些消息）
输入一条信息（Thisis a message: The you smile until forever），并且Ctrl+z退出shell

./bin/kafka-console-producer.sh --broker-list localhost:9092 --topic testThis is a message: The you smile until forever

comsumer
# Start a consumer（开启一个消费者）
输入命令之后打印出一些信息，最后面显示了刚刚输入的信息：Thisis a message: The you smile until forever

./bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic test --from-beginningThis is a message: The you smile until forever
