部署说明

本文使用kafka单节点安装及配置，并使用kafka自带的zookeeper。一般kafka需要起三个kafka构成集群，可以连单独的zookeeper，本文不涉及。

kafka下载

1. 根据需要下载对应版本的安装包，下载地址： https://archive.apache.org/dist/kafka/
2. 上传安装包并解压重命名（路径自定义）： 如：上传到 /opt 路径下 解压和重命名：

cd opt
tar -zxvf kafka_2.12-2.5.0.tgz
mv kafka_2.12-2.5.0 kafka

修改zookeeper配置

vim kafka/config/zookeeper.properties

dataDir=/opt/kafka
# the port at which the clients will connect
clientPort=2181
# disable the per-ip limit on the number of connections since this is a non-production config
maxClientCnxns=100
# Disable the adminserver by default to avoid port conflicts.
# Set the port to something non-conflicting if choosing to enable this
admin.enableServer=false
# admin.serverPort=8080

修改kafka配置

vim kafka/config/server.properties

broker.id=0
listeners=PLAINTEXT://192.168.111.111:9092
advertised.listeners=PLAINTEXT://192.168.111.111:9092
log.dirs=/opt/kafka/kafka-logs
zookeeper.connect=192.168.111.111:2181
# 本机ip
host.name=192.168.111.111
