Day08_02_分布式教程之Windows下搭建Zookeeper

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.
