kafka集群搭建和操作

kafka集群搭建

环境:

192.168.28.131:zookeeper,kafka
192.168.28.132:zookeeper,kafka
192.168.28.133:zookeeper,kafka
jdk1.8

 

zookeeper集群搭建

第一步,下载kafka和zookeeper包(注意:在kafka2.8以后可以不需要zookeeper)

wget -c https://dlcdn.apache.org/kafka/3.1.0/kafka_2.12-3.1.0.tgz --no-check-certificate
wget -c https://archive.apache.org/dist/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz

第二步,编辑zoo.cfg配置文件

tickTime=2000
initLimit=5
syncLimit=2
dataDir=/data/zookeeper/data
clientPort=2181
server.1=192.168.28.131:2888:3888
server.2=192.168.28.132:2888:3888
server.3=192.168.28.131:2888:3888

第三补,添加myid

cat /data/zookeeper/data/myid 
3

第四步,在另外两台机器重复第二步和第三步

 

第五步,查看zookeeper集群状态(3个节点都看一下)

[root@node3 data]# /opt/zookeeper/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/bin/../conf/zoo.cfg
Mode: leader

kafka集群部署

第一步,编辑kafka配置文件(3台机器都要配置),注意红色字体根据需要修改

[root@node3 config]# cat server.properties 
broker.id=131
port=9092
host.name=192.168.28.131
num.network.threads=3
num.io.threads=8
socket.send.buffer.bytes=102400
socket.receive.buffer.bytes=102400
socket.request.max.bytes=104857600
log.dirs=/data/kafka-log
num.partitions=9
num.recovery.threads.per.data.dir=1
log.retention.hours=72
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
log.cleaner.enable=true
log.cleanup.policy=delete
zookeeper.connect=192.168.28.133:2181,192.168.28.132:2181,192.168.28.131:2181
zookeeper.connection.timeout.ms=6000
delete.topic.enable=true
broker.list=192.168.28.133:9092,192.168.28.132:9092,192.168.28.131:9092

第二步,3台机器启动kafka服务

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

第三步,查看是否ok

/opt/zookeeper/bin/zkCli.sh
.....

[zk: localhost:2181(CONNECTED) 0] ls /brokers/ids
[132, 133, 131]

日常操作

查看topic

bin/kafka-topics.sh --list --bootstrap-server localhost:9092

创建topic

bin/kafka-topics.sh --create --bootstrap-server localhost:9092 --topic test2 --replication-factor 2 --partitions 2

有了主题了,开始创建生产者

bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test1

创建消费者接收消息,其中 --from-beginning代表从头开始接收消息,也就是说在没有开启消费者之前的消息,也可以收到

bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test1 --from-beginning

 查看group

./kafka-consumer-groups.sh --list --zookeeper IP:2181
