macOS启动Kafka

目录

• kafka目录结构
• 先启动zookeeper
• 后启动kafka
• 创建topic
• 创建一个生产者
• 创建一个消费者

kafka目录结构

# kafka安装目录
/usr/local/Cellar/kafka/2.6.0

# 配置文件目录
/usr/local/etc/kafka/

# 如果超时，在server.properties中增加
zookeeper.connection.timeout.ms=6000000

先启动zookeeper

/usr/local/Cellar/kafka/2.6.0/bin/zookeeper-server-start 
/usr/local/etc/kafka/zookeeper.properties &

cd /usr/local/Cellar/kafka/2.6.0/bin
./zookeeper-server-start /usr/local/etc/kafka/zookeeper.properties &

# 不使用配置启动的方式
zkServer start
zkServer stop

检测是否启动成功
ps aux | grep zookeeper

(上图为启动成功时截图)

后启动kafka

/usr/local/Cellar/kafka/2.6.0/bin/kafka-server-start 
/usr/local/etc/kafka/server.properties &


# zk如果使用配置启动，kafka也得使用配置启动，不然会报错
cd /usr/local/Cellar/kafka/2.6.0/bin
./kafka-server-start /usr/local/etc/kafka/server.properties &

检测是否启动成功
ps aux | grep kakfka

(上图为启动成功时截图)

创建topic

kafka-topics --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic basket_test

查看topic list
kafka-topics --list --zookeeper localhost:2181

要是报：Timed out waiting for connection while in state: CONNECTING ，那就是没有启动zk、kafka

创建一个生产者

kafka-console-producer --broker-list localhost:9092 --topic basket_test

进入指定生产者
kafka-console-producer --broker-list localhost:9092 --topic basket_test

创建一个消费者

kafka-console-consumer --bootstrap-server localhost:9092 --topic basket_test --from-beginning
