Zookeeper下载与安装教程（for windows）

  • Zookeeper下载
  • Zookeeper安装
    • 前置条件
    • 单机模式部署
    • 伪集群模式部署
    • 集群模式部署
  • Zookeeper简单操作

Zookeeper下载

1、首先进入apache官网

  • https://www.apache.org/
    然后点击中间的Projects->Project List菜单项进入ProjectList页面，如下图：
    在这里插入图片描述
    2、在ProjectList页面中找点Zookeeper链接，然后点击进入Zookeeper的主页，如下图：
    在这里插入图片描述
    3、在Zookeeper主页的顶部点击菜单Project->Releases，进入Zookeeper发布版本信息页面，如下图：
    在这里插入图片描述
    4、找到最新版的下载链接，如下图：
    在这里插入图片描述
    5、目前最新版本是3.6.2，点击链接进入下载的镜像地址页面，如下图：

Zookeeper安装

前置条件

  • 已安装JDK
  • 已配置了环境变量JAVA_HOME，PATH

单机模式部署

1、解压apache-zookeeper-3.6.2-bin.tar.gz至D:\zookeeper\apache-zookeeper-3.6.2-bin。
2、复制D:\zookeeper\apache-zookeeper-3.6.2-bin\conf\zoo-sample.cfg，粘贴为D:\zookeeper\apache-zookeeper-3.6.2-bin\zoo.cfg。
3、修改D:\zookeeper\apache-zookeeper-3.6.2-bin\zoo.cfg。
主要修改了dataDir，如下：

  1. # The number of milliseconds of each tick
  2. tickTime=2000
  3. # The number of ticks that the initial 
  4. # synchronization phase can take
  5. initLimit=10
  6. # The number of ticks that can pass between 
  7. # sending a request and getting an acknowledgement
  8. syncLimit=5
  9. # the directory where the snapshot is stored.
  10. # do not use /tmp for storage, /tmp here is just 
  11. # example sakes.
  12. dataDir=D:\\zookeeper\\data
  13. # the port at which the clients will connect
  14. clientPort=2181
  15. # the maximum number of client connections.
  16. # increase this if you need to handle more clients
  17. #maxClientCnxns=60
  18. #
  19. # Be sure to read the maintenance section of the 
  20. # administrator guide before turning on autopurge.
  21. #
  22. # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
  23. #
  24. # The number of snapshots to retain in dataDir
  25. #autopurge.snapRetainCount=3
  26. # Purge task interval in hours
  27. # Set to "0" to disable auto purge feature
  28. #autopurge.purgeInterval=1
  30. ## Metrics Providers
  31. #
  32. # https://prometheus.io Metrics Exporter
  33. #metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMetricsProvider
  34. #metricsProvider.httpPort=7000
  35. #metricsProvider.exportJvmInfo=true
  37. # server.N = YYY:A:B

配置文件关键配置项说明：

  • 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。
  • initLimit：LF初始通信时限，集群中的follower服务器（F）与leader服务器（L）之间初始连接时能容忍的最多心跳数（tickTime的数量）。
  • syncLimit：LF同步通信时限，集群中的follower服务器与leader服务器之间请求和应答之间能容忍的最多心跳数（tickTime的数量）。
  • 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。
  • clientPort：客户端连接端口，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
  • autopurge.snapRetainCount：保留数量。
  • autopurge.purgeInterval：清理时间间隔，单位：小时。
  • server.N = YYY:A:B，其中N表示服务器编号，YYY表示服务器的IP地址，A为LF通信端口，表示该服务器与集群中的leader交换的信息的端口。B为选举端口，表示选举新leader时服务器间相互通信的端口（当leader挂掉时，其余服务器会相互通信，选择出新的leader）。一般来说，集群中每个服务器的A端口都是一样，每个服务器的B端口也是一样。但是当所采用的为伪集群时，IP地址都一样，只能时A端口和B端口不一样。

4、启动Zookeeper服务器。
在bin目录下执行

  1. zkServer.cmd

就可以了，如下：

  1. D:\zookeeper\apache-zookeeper-3.6.2-bin\bin>zkServer.cmd
  3. D:\zookeeper\apache-zookeeper-3.6.2-bin\bin>call "C:\Java\jre1.8.0_144"\bin\java "-Dzookeeper.log.dir=D:\zookeeper\apache-zookeeper-3.6.2-bin\bin\..\logs" "-Dzookeeper.root.logger=INFO,CONSOLE" "-Dzookeeper.log.file=zookeeper-Administrator-server-ECS-A0E1-0001.log" "-XX:+HeapDumpOnOutOfMemoryError" "-XX:OnOutOfMemoryError=cmd /c taskkill /pid %%p /t /f" -cp "D:\zookeeper\apache-zookeeper-3.6.2-bin\bin\..\build\classes;D:\zookeeper\apache-zookeeper-3.6.2-bin\bin\..\build\lib\*;D:\zookeeper\apache-zookeeper-3.6.2-bin\bin\..\*;D:\zookeeper\apache-zookeeper-3.6.2-bin\bin\..\lib\*;D:\zookeeper\apache-zookeeper-3.6.2-bin\bin\..\conf" org.apache.zookeeper.server.quorum.QuorumPeerMain "D:\zookeeper\apache-zookeeper-3.6.2-bin\bin\..\conf\zoo.cfg"

伪集群模式部署

伪集群模式就是在同一主机启动多个zookeeper并组成集群

1、在同一个主机上，通过复制得到三个zookeeper实例

  • zookeeper-3.6.2-12181
  • zookeeper-3.6.2-12182
  • zookeeper-3.6.2-12183

2、对三个zookeeper节点进行配置
zookeeper1配置文件/conf/zoo.cfg修改如下：

  1. tickTime=2000
  2. initLimit=5
  3. syncLimit=2
  4. dataDir=D:\\zookeeper\\data\\zookeeper-cluster\\zookeeper-3.6.2-12181\\data
  5. clientPort=12181
  7. server.1=127.0.0.1:12888:13888
  8. server.2=127.0.0.1:14888:15888
  9. server.3=127.0.0.1:16888:17888

注：server.1中的数字1为服务器的ID，需要与data/myid文件中的id一致

zookeeper2配置文件/conf/zoo.cfg修改如下：

  1. tickTime=2000
  2. initLimit=5
  3. syncLimit=2
  4. dataDir=D:\\zookeeper\\data\\zookeeper-cluster\\zookeeper-3.6.2-12182\\data
  5. clientPort=12182
  7. server.1=127.0.0.1:12888:13888
  8. server.2=127.0.0.1:14888:15888
  9. server.3=127.0.0.1:16888:17888

zookeeper3配置文件/conf/zoo.cfg修改如下：

  1. tickTime=2000
  2. initLimit=5
  3. syncLimit=2
  4. dataDir=D:\\zookeeper\\data\\zookeeper-cluster\\zookeeper-3.6.2-12183\\data
  5. clientPort=12183
  7. server.1=127.0.0.1:12888:13888
  8. server.2=127.0.0.1:14888:15888
  9. server.3=127.0.0.1:16888:17888

3、分别启动三个zookeeper节点

集群模式部署

集群模式就是在不同主机上安装zookeeper然后组成集群的模式，可以参考伪集群模式安装

1、在三台机器上分别部署1个ZooKeeper实例
2、zookeeper配置文件conf/zoo.cfg，如下：

  1. tickTime=2000
  2. initLimit=5
  3. syncLimit=2
  4. dataDir=D:\\zookeeper\\data
  5. clientPort=2181
  7. server.1=127.0.0.1:2888:3888
  8. server.2=127.0.0.2:2888:3888
  9. server.3=127.0.0.3:2888:3888

3、zookeeper的data/myid配置，使用如下命令：
当然zookeeper1 对应的是 1，zookeeper2 对应的是 2，zookeeper3 对应的是 3
4、分别启动三个zookeeper节点，即完成对ZooKeeper集群的安装

Zookeeper简单操作

1、使用客户端连接Zookeeper服务。
在bin目录下执行

  1. zkCli.cmd -server 127.0.0.1:2181

就可以了，如下：

  1. D:\zookeeper\apache-zookeeper-3.6.2-bin\bin>zkCli.cmd -server 127.0.0.1:2181
  2. Connecting to 127.0.0.1:2181

  34. WatchedEvent state:SyncConnected type:None path:null
  35. [zk: 127.0.0.1:2181(CONNECTED) 0]

2、在客户端使用ls命令来查看当前Zookeeper中所包含的内容：

  • 命令：ls /

    [zk: 127.0.0.1:2181(CONNECTED) 0] ls /
    [zookeeper]
    [zk: 127.0.0.1:2181(CONNECTED) 1]

3、创建一个新的znode节点“zk”以及与它关联的字符串

  • 命令：create zk/ myData

    [zk: 127.0.0.1:2181(CONNECTED) 1] create /zk myData
    Created /zk
    [zk: 127.0.0.1:2181(CONNECTED) 2] ls /
    [zk, zookeeper]
    [zk: 127.0.0.1:2181(CONNECTED) 3]

4、获取znode节点”zk”

  • 命令：get /zk

    [zk: 127.0.0.1:2181(CONNECTED) 3] get /zk
    myData
    [zk: 127.0.0.1:2181(CONNECTED) 4]

5、删除znode节点”zk”

  • 命令：delete /zk

    [zk: 127.0.0.1:2181(CONNECTED) 4] delete /zk
    [zk: 127.0.0.1:2181(CONNECTED) 5]

6、退出客户端

  • 命令：quit

    [zk: 127.0.0.1:2181(CONNECTED) 5] quit
