centos 7 安装kafka 2.6.2（集群）

小伙伴们，你们好，我是老寇

一、前提条件

192.168.1.1 (安装kafka，点点我)

192.168.1.2 (安装kafka，点点我)

192.168.1.3 (安装kafka，点点我)

二、安装过程

1.3台主机都执行如下命令

mkdir -p /data/kafka/logs
mkdir -p /data/zookeeper/logs
mkdir -p /data/zookeeper/data

chown 777 -R /data/kafka/logs
chown 777 -R /data/zookeeper/data
chown 777 -R /data/zookeeper/logs

touch /data/zookeeper/data/myid

# 注意 每个节点的myid值是不一样的 需要在不同的节点上执行下面操作
#节点1 配置
echo "1" > /data/zookeeper/data/myid

#节点2 配置
echo "2" > /data/zookeeper/data/myid

#节点3 配置
echo "3" > /data/zookeeper/data/myid

2.三台主机配置conf/zookeeper.properties

解释：myid与zookeeper配置的1，2，3是相对应的

dataDir=/data/zookeeper/data
dataLogDir=/data/zookeeper/logs
clientPort=2181
maxClientCnxns=2000
initLimit=5
syncLimit=2
server.1=192.168.1.1:2888:3888
server.2=192.168.1.2:2888:3888
server.3=192.168.1.3:2888:3888

3.三台主机配置conf/server.properties

192.168.1.1 配置

log.dirs=/data/kafka/logs
listeners=PLAINTEXT://:9092
advertised.listeners=PLAINTEXT://192.168.1.1:9092
zookeeper.connect=192.168.1.1:2181,192.168.1.2:2181,192.168.1.3:2181

** 192.168.1.2 配置**

log.dirs=/data/kafka/logs
listeners=PLAINTEXT://:9092
advertised.listeners=PLAINTEXT://192.168.1.2:9092
zookeeper.connect=192.168.1.1:2181,192.168.1.2:2181,192.168.1.3:2181

** 192.168.1.3 配置**

log.dirs=/data/kafka/logs
listeners=PLAINTEXT://:9092
advertised.listeners=PLAINTEXT://192.168.1.3:9092
zookeeper.connect=192.168.1.1:2181,192.168.1.2:2181,192.168.1.3:2181

** 4.启动zookeeper**

cd /usr/local/kafka

./bin/zookeeper-server-start.sh config/zookeeper.properties

5.启动kafka

cd /usr/local/kafka

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

6.查看端口占用

netstat -ntlp

大功告成
