zookeeper安装(Windows版)

背景

由于系统限制，暂时用windows作为开发环境。
开发环境：windows 10
zookeeper版本： zookeeper-3.6.2

过程

下载

到zookeeper-3.6.2上下载，直接下载带有bin的tar.gz 。
如果是另一个包，在启动的时候会报一个错：
错误: 找不到或无法加载主类 org.apache.zookeeper.server.quorum.QuorumPeerMain
这时候因为缺少lib的包，到上面网页下载一个bin的包，然后将里面的lib直接复制过去。

配置

1. conf配置
   路径：\apache-zookeeper-3.6.2\conf
   修改：复制一份zoo_sample.cfg，修改为zoo.cfg。
   增加dataDir配置

# The number of milliseconds of each tick
# 心跳的时间间隔
tickTime=2000

# The number of ticks that the initial 
# synchronization phase can take
# Follower 服务器初始化连接时最长能忍受多少个心跳时间间隔数
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.
# Zookeeper 将写数据的日志文件也保存在这个目录里
dataDir=F://apache-zookeeper-3.6.2//apache-zookeeper-3.6.2//data

# the port at which the clients will connect
# Zookeeper 会监听这个端口，接受客户端的访问请求
clientPort=2182

# 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

## Metrics Providers
#
# https://prometheus.io Metrics Exporter
#metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMetricsProvider
#metricsProvider.httpPort=7000
#metricsProvider.exportJvmInfo=true

脚本介绍

• zkServer.sh： ZooKeeper服务器的启动、停止和重启脚本；
• zkCli.sh：ZooKeeper的简易客户端；
• zkEnv.sh： 设置ZooKeeper的环境变量；
• zkCleanup.sh： 清理ZooKeeper历史数据，包括事务日志文件和快照数据文件。

总结

安装了以下zookeeper，操作起来很像文件目录+树状结构的感觉，每个node上既有path代表唯一路径，上面还有值，还有子目录。就是查看起来不太好查看，感觉可以加一个前端可视化放边后面的阅读。
后面用java来操作zookeeper，写个demo来展示下。
