Windows安装Kafka

1.安装JDK并配置好对应的环境变量

● 新建一个文件夹jre

● 1.环境变量如下-安装的路径

● 2.点击path新建

● 3.建一个系统变量

.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar

2.安装配置Zookeeper

1.下载安装包Apache Zookeeper

下载

2.解压并进入Zookeeper目录

● 2.1将conf下的zoo_sample.cfg重命名为 zoo.cfg

● 2.2 打开zoo.cfg，修改数据存放位置dataDir
dataDir=D:/OnlineSoftWare/apache-zookeeper-3.7.1/data

dataDir=D:/OnlineSoftWare/apache-zookeeper-3.7.1/data
# 防止端口8080启动后被占用，这里考虑先配置下
admin.serverPort=8081

防止端口8080启动后被占用，这里考虑先配置下

admin.serverPort=8081

● 2.3 添加系统变量

● 2.4在path新建一个

3.打开新的cmd，输入"zkServer"，运行Zookeeper

● 只要不报错就是成功，如果报错下面这个只需要把2.2的admin端口配置了

注意不能关闭这个接口~因为kafka需要先启动zookeeper!

3.安装Kafka

3.1 下载安装包

Kafka下载
下载二进制版本，如图

3.2、 解压并进入Kafka目录，

笔者：D:\OnlineSoftWare\kafka_2.13-3.3.1

3、 进入config目录找到文件server.properties并打开
找到并编辑日志保存的位置 log.dirs、listener,其中kafka-logs是自己新建的文件夹

listeners=PLAINTEXT://0.0.0.0:9092
advertised.listeners=PLAINTEXT://localhost:9092
log.dirs=D:\OnlineSoftWare\kafka_2.13-3.3.1\kafka-logs
broker.id=1

进入Kafka安装目录D:\OnlineSoftWare\kafka_2.13-3.3.1，按下Shift+右键，选择“打开命令窗口”选项，打开命令行

.\bin\windows\kafka-server-start.bat .\config\server.properties

到这里就安装完毕了！

linux下安装的还在编写中…
