## Windows下搭建Zookeeper ##

### 一. 下载Zookeeper ###

版本: Zookeeper 3.4.6  
[官网下载地址][Link 1]

### 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.
