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：

2、在ProjectList页面中找点Zookeeper链接，然后点击进入Zookeeper的主页，如下图：

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：

4、找到最新版的下载链接，如下图：

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：

6、在国内直接选择清华大学的镜像下载链接进行下载就行，下载后如下图：

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：

# 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:\\zookeeper\\data
# 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

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

# 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

zkServer.cmd

就可以了，如下：

D:\zookeeper\apache-zookeeper-3.6.2-bin\bin>zkServer.cmd

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：

tickTime=2000
initLimit=5
syncLimit=2
dataDir=D:\\zookeeper\\data\\zookeeper-cluster\\zookeeper-3.6.2-12181\\data
clientPort=12181

server.1=127.0.0.1:12888:13888
server.2=127.0.0.1:14888:15888
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：

tickTime=2000
initLimit=5
syncLimit=2
dataDir=D:\\zookeeper\\data\\zookeeper-cluster\\zookeeper-3.6.2-12182\\data
clientPort=12182

server.1=127.0.0.1:12888:13888
server.2=127.0.0.1:14888:15888
server.3=127.0.0.1:16888:17888

zookeeper3配置文件/conf/zoo.cfg修改如下：

tickTime=2000
initLimit=5
syncLimit=2
dataDir=D:\\zookeeper\\data\\zookeeper-cluster\\zookeeper-3.6.2-12183\\data
clientPort=12183

server.1=127.0.0.1:12888:13888
server.2=127.0.0.1:14888:15888
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：

tickTime=2000
initLimit=5
syncLimit=2
dataDir=D:\\zookeeper\\data
clientPort=2181

server.1=127.0.0.1:2888:3888
server.2=127.0.0.2:2888:3888
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

zkCli.cmd -server 127.0.0.1:2181

就可以了，如下：

D:\zookeeper\apache-zookeeper-3.6.2-bin\bin>zkCli.cmd -server 127.0.0.1:2181

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
