CentOS8安装Kafka

1、下载kafka
http://kafka.apache.org/downloads
2、解压tgz包

tar -zxvf kafka_2.13-2.8.0.tgz
mv kafka_2.13-2.8.0 ./kafka
cd /home/data
mkdir kafka
chmod -R 777 kafka
mkdir zookeeper
chmod -R 777 zookeeper
cd /opt/kafka/conf
vim server.properties

修改

#根据实际选择listeners=PLAINTEXT://10.0.0.63://:9092或者listeners=10.0.0.63://:9092
listeners=PLAINTEXT://10.0.0.63:9092
advertised.listeners=PLAINTEXT://10.0.0.63:9092
#改为自己的路径
log.dirs=/home/data/kafka
zookeeper.connect=10.0.0.63:2181
#新增可以删除topic
delete.topic.enable=true

vim zookeeper.properties

dataDir=/home/data/zookeeper

3、放开2181和9092端口

firewall-cmd --zone=public --add-port=2181/tcp --permanent
firewall-cmd --zone=public --add-port=9092/tcp --permanentsystemctl restart firewalld

4、启动zookeeper和kafka

cd /opt/kafka/
./bin/zookeeper-server-start.sh ./config/zookeeper.properties &
./bin/kafka-server-start.sh ./config/server.properties &

5、附一个启动脚本

#!/bin/bash
#启动zookeeper
cd /opt/kafka
./bin/zookeeper-server-start.sh ./config/zookeeper.properties &
sleep 3
#启动kafka
./bin/kafka-server-start.sh ./config/server.properties &
