Windows下搭建Zookeeper
一. 下载Zookeeper
版本: Zookeeper 3.4.6
官网下载地址
二. 安装Zookeeper
1. 解压Zookeeper压缩包


2. 修改Zookeeper配置文件
将E:\zookeeper-3.4.6\conf\里面的zoo_sample.cfg 文件改为 zoo.cfg.

主要修改一下日志位置,具体配置文件如下:
# 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=E:\\zookeeper-3.4.6\\data
dataLogDir=E:\\zookeeper-3.4.6\\log
# 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
配置文件简单解析:
1️⃣.tickTime: 这个时间是作为 Zookeeper 服务器之间或客户端与服务器之间维持心跳的时间间隔.也就是每个 tickTime 时间就会发送一个心跳.
2️⃣.dataDir: 顾名思义就是 Zookeeper 保存数据的目录,默认情况下,Zookeeper将写数据的日志文件也保存在这个目录里.
3️⃣.dataLogDir: 顾名思义就是 Zookeeper 保存日志文件的目录.
4️⃣.clientPort: 这个端口就是客户端连接 Zookeeper 服务器的端口,Zookeeper 会监听这个端口,接受客户端的访问请求.
三. 启动Zookeeper
进入到bin目录,并且启动zkServer.cmd,这个脚本中会启动一个java进程.

启动后可以看到QuorumPeerMain的进程:

也可以启动客户端连接一下:

到此Zookeeper安装成功.
