Windows下安装

下载并安装

在zookeeper官网找到最新的稳定版本tar.gz
解压到本地，并在根目录创建一个data文件夹

修改配置

进入conf目录中，将zoo_sample.cfg修改为zoo.cfg，zoo.cfg是zookeeper的配置文件。

修改配置，将用于存储内存数据库快照文件dataDir指定到刚才创建的data目录，注意windows下的路径分隔符为/，修改后的zoo.cfg如下

# 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=F:/DevResource/apache-zookeeper-3.7.1-bin/data
# 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

启动服务器（单机版）

在bin目录下执行zkServer.cmd

启动成功！
