Windows 系统下载安装 ZooKeeper

这里演示 Apache ZooKeeper 3.4.14 版本的下载与安装

1. 进入官网下载 ZooKeeper

ZooKeeper 官网地址: https://zookeeper.apache.org/

点击上面官网链接进入官网

跳转页面后，点击下载

2. Zookeeper 安装

1. 下载完后直接解压，解压后目录如下：

   

2. 创建一个 data 文件夹和 log 文件夹

   

3. 进入 config 文件夹，将 zoo_sample.cfg 复制一份，并重命名 zoo.cfg

   

4. 修改 zoo.cfg 内的配置信息

   dataDir 和 dataLogDir 根据自己的真实路径填写。就是我们刚刚创建的 data 和 log 文件夹的位置

   

   # 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:\\Code\\tool\\java\\zookeeper-3.4.14\\zookeeper-3.4.14\\data
   dataLogDir=D:\\Code\\tool\\java\\zookeeper-3.4.14\\zookeeper-3.4.14\\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
   

3. 运行 ZooKeeper

1. 进入 bin 目录，启动 zkServer.cmd

   

   如果闪退的话，就代表启动失败，可能是我们刚刚配置错误了。

   编辑 zkServer.cmd 文件，增加 @pause 让它报错时停下来，然后根据报错百度查询解决方案。

   java.io.IOException: Unable to create data directory XXX 代表是文件路径错误了，检查 dataDir 和 dataLogDir 的路径

   @pause
   endlocal
   

2. 运行成功
