Windows kafka 简单集群搭建

1.环境说明

项目	版本
操作系统环境	Windows 11 / 64 位操作系统
Zookeeper环境	zookeeper-3.4.8
kafka环境	kafka_2.12-3.7.0

2.Zookeeper集群搭建

要搭建kafka集群首先要搭建Zookeeper集群

2.1 ZooKeeper下载

ZooKeeper下载地址
本文选用的是3.4.8版本

2.2 ZooKeeper安装

拷贝多份zookeeper程序，此处设置三个server，分别创建目录Server-A、Server-B、Server-C，每个目录下存放一份zookeeper程序

2.2.1 解压zookeeper-3.4.8.tar.gz

2.2.2 进入conf目录下，复制zoo_sample.cfg为zoo.cfg

2.2.3 修改zoo.cfg文件

要先创建对应文件夹 E:/zookeeper/tmp/zookeeper-A

服务A:

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=E:/zookeeper/tmp/zookeeper-A
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
server.1=localhost:2887:3887
server.2=localhost:2888:3888
server.3=localhost:2889:3889
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

服务B:

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=E:/zookeeper/tmp/zookeeper-B
# the port at which the clients will connect
clientPort=2182
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
server.1=localhost:2887:3887
server.2=localhost:2888:3888
server.3=localhost:2889:3889
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

服务C:

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=E:/zookeeper/tmp/zookeeper-C
# the port at which the clients will connect
clientPort=2183
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
server.1=localhost:2887:3887
server.2=localhost:2888:3888
server.3=localhost:2889:3889
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

2.2.4 生成myid文件

进入E:\zookeeper\tmp\zookeeper-A文件夹下，点击鼠标右键，选择在终端打开，执行命令echo 3 > myid

2.2.5 注意事项

1.注意生成的myid文件中有空格 去除空格，否者无法启动
1.java环境 环境变量中没配置java环境变量也会导致启动失败

2.3 zookeeper启动

双击zkServer.cmd脚本即可启动，如下图所示：

3.kafka集群搭建

3.1 kafka下载

kafka下载地址

3.2 kafka安装

拷贝多份kafka程序，此处设置三个broker，分别创建目录kafka_A、kafka_B、kafka_C，每个目录下存放一份kafka程序

3.2.1 kafka_2.12-3.7.0.tgz

3.2.2 修改server.properties文件

# There are a few important trade-offs here:
#    1. Durability: Unflushed data may be lost if you are not using replication.
#    2. Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush.
#    3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to excessive seeks.
# The settings below allow one to configure the flush policy to flush data after a period of time or
