必须要有 jdk 环境 , 我使用jdk1.8
安装 jdk略
下载 Zookeeper在官网 http://zookeeper.apache.org/ 下载 zookeeper. 我下载的是zookeeper-3.7.0 版本
https://zookeeper.apache.org/releases.html
解压到目录解压 zookeeper-3.7.0 至 D:zookeeper-3.7.0
Zookeeper安装 ZooKeeper 的安装模式分为三种，分别为：单机模式（stand-alone）、集群模式和集群伪分布模式。ZooKeeper 单机模式的安装相对比较简单，如果第一次接触 ZooKeeper 的话， 建议安装 ZooKeeper 单机模式或者集群伪分布模式。
安装单击模式 配置cfg文件 D:zookeeper-3.7.0conf 复制 zoo_sample.cfg 并粘贴到当前目录下，命名 zoo.cfg
# 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=D:/zookeeper-3.7.0-bin/simpleData # 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 # # 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 ## Metrics Providers # # https://prometheus.io Metrics Exporter #metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMetricsProvider #metricsProvider.httpPort=7000 #metricsProvider.exportJvmInfo=true
修改data目录
dataDir=D:/zookeeper-3.7.0-bin/simpleData

看到了这个,说明我们的代码好像是不需要参数的
set ZOOCFGDIR=%~dp0%…conf
%~dp0?
Windows脚本 - %~dp0的含义
更改当前目录为批处理本身的目录
有些晕吧？不急，我举例
比如你有个批处理a.bat在D:qq文件夹下
a.bat内容为
cd /d %~dp0
在这里
cd /d %~dp0的意思就是cd /d d:qq
%0代表批处理本身 d:qqa.bat
~dp是变量扩充
d既是扩充到分区号 d:
p就是扩充到路径 qq
dp就是扩充到分区号路径 d:qq参考: https://www.cnblogs.com/smwikpedia/archive/2009/03/30/1424749.html

伪集群就是说集群所有的机器都在一台机器上，但是还是以集群的特性对外提供服务。这种模式和集群模式非常类似，只是把 zoo.cfg 做一些修改:
zoo.cfg配置 分别创建不同的数据目录
D:/zookeeper-3.7.0/zk/data/1 D:/zookeeper-3.7.0/zk/data/2 D:/zookeeper-3.7.0/zk/data/3
创建目录如下
D:/zookeeper-3.7.0/ conf1/zoo.cfg conf2/zoo.cfg conf3/zoo.cfg

需要确保每台服务器的 myid 文件中数字不同，并且和自己所在机器的 zoo.cfg 中 server.id=host:port:port 的id值一样。id的范围是1～255。
启动ZooKeeper复制zkServer.cmd适当修改命令重命名为zkServer-1.cmd,zkServer-2.cmd,zkServer-3.cmd
