ookeeper支持windows、linux、mac等操作系统，其搭建方式也有集群、伪集群、单机环境。下面研究三种方式的搭建。
单机环境:windows操作系统
伪集群:windows
集群:linux
单机环境
下面在windows下面搭建zookeeper的单机环境。windows下面也适合做开发。但是不适合生产环境的部署安装。
java安装
zookeeper依赖于Java环境，所以先自行安装JDK。
Zookeeper下载及其安装
(1)下载zookeeperxxx.tar.gz
载地址:http://zookeeper.apache.org/releases.html 下载xxx.tar.gz解压即可，里面有sh脚本，也有cmd脚本。
(2)解压下载文件
(3)在conf目录下面创建zoo.cfg (在conf目录下面提供了一分样本文件zoo_sample.cfg),或者复制一分样本文件改名为zoo.cfg
# 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=E:北大青鸟Y2ookeeperzookeeper-3.4.6data # 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
解释:
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。
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。
dataLogDir：log目录, 同样可以是任意目录. 如果没有设置该参数, 将使用和dataDir相同的设置.
clientPort：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。
(4)在对应目录建立上面的data目录即可
(5)启动zookeeper

3.测试
(1)用netstat或者jps查看都可以
C:UsersAdministrator>netstat -ano|findstr 2181 TCP 0.0.0.0:2181 0.0.0.0:0 LISTENING 15532 TCP [::]:2181 [::]:0 LISTENING 15532 C:UsersAdministrator>jps -l 19320 sun.tools.jps.Jps 15532 org.apache.zookeeper.server.quorum.QuorumPeerMain 4780
(2)zkCli.cmd连接进行测试:
PS E:zookeeperzookeeper-3.4.13in> .zkCli.cmd Connecting to localhost:2181 ......... [zk: localhost:2181(CONNECTING) 0] 2019-03-07 18:23:07,894 [myid:] - INFO [main-SendThread(localhost:2181):ClientCnxn$SendThread@1303] - Session establishment complete on server localhost/0:0:0:0:0:0:0:1:2181, sessionid = 0x10035685eb40002, negotiated timeout = 30000 WATCHER:: WatchedEvent state:SyncConnected type:None path:null [zk: localhost:2181(CONNECTED) 0]

集群
1.准备三台centos操作系统，ip分别为:
192.168.1.130 我们称为A机器
192.168.1.131 我们称为B机器
192.168.1.133 我们称为C机器
2.建立相同的目录并上传zookeeperxxx.tar.gz
3.解压上面的目录 (三个做相同操作)
4.复制confzoo_sample.cfg到conzoo.cfg目录下:
[root@localhost conf]# cp ./zoo_sample.cfg ./zoo.cfg
[root@localhost conf]# ls
configuration.xsl log4j.properties zoo.cfg zoo_sample.cfg
5.修改 zoo.cfg
tickTime = 2000 dataDir = /opt/zookeeper/zookeeper-3.4.13/data clientPort = 2181 initLimit = 5 syncLimit = 2 server.1=192.168.1.130:2888:3888 server.2=192.168.1.131:2888:3888 server.3=192.168.1.133:2888:3888
6.同时创建三个服务器对应的数据目录
mkdir /opt/zookeeper/zookeeper-3.4.13/data
7.在三个机器的对应的data目录下面分别创建对应的id文件(非常重要)
A机器:
[root@localhost data]# echo "1">myid [root@localhost data]# cat myid 1
B机器：
[root@localhost data]# echo "2">myid [root@localhost data]# cat myid 2
C机器
[root@localhost data]# echo "3">myid [root@localhost data]# cat myid 3
8.接下来启动三个服务器即可(同时发送命令)
/opt/zookeeper/zookeeper-3.4.13/bin/zkServer.sh start
9.JPS查看JVM
三个服务器都有主类为QuorumPeerMain的PID即启动成功。
10.查看集群状态
/opt/zookeeper/zookeeper-3.4.13/bin/zkServer.sh status
A机器:
B机器:
C机器:
