Windows 系统下载安装 ZooKeeper教程

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
