必须要有 jdk 环境 , 我使用jdk1.8

略

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 zookeeper-3.7.0 至 D:\zookeeper-3.7.0

ZooKeeper 分为三种安装方式：单机模式（stand-alone）、集群模式和集群伪分布模式。ZooKeeper 如果第一次接触，单机模式的安装相对简单 ZooKeeper 的话， 建议安装 ZooKeeper 单机模式或集群伪分布模式。

D:\zookeeper-3.7.0\conf 复制 zoo_sample.cfg 并粘贴在当前目录下，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

为了方便看日志，使用cmd启动

​ 报错了,为什么呢? 百度无果,可能是因为我作死使用的最新版本

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:\qq\a.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

​ 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:

​ 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

windows cmd运行不需要参数,如果添加了参数就会报如下需错误
