安装jdk
安装Zookeeper.
在官网http://mirrors.hust.edu.cn/apache/zookeeper/下载zookeeper.我下载的是zookeeper-3.4.10版本。
解压zookeeper-3.4.10至D:\dev\zookeeper\zookeeper-3.4.10.
在D:\dev\zookeeper新建data及log目录。
ZooKeeper的安装模式分为三种，分别为：单机模式（stand-alone）、集群模式和集群伪分布模式。ZooKeeper
单机模式的安装相对比较简单，如果第一次接触ZooKeeper的话，建议安装ZooKeeper单机模式或者集群伪分布模式。

安装单机模式。

至D:\dev\zookeeper\zookeeper-3.4.10\conf 复制 zoo_sample.cfg 并粘贴到当前目录下，命名zoo.cfg.

1、编辑zoo.cfg.修改如下配置

# 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:\\dev\\zookeeper\\data
dataLogDir=D:\\dev\\zookeeper\\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

2、cmd命令下进入D:\dev\zookeeper\zookeeper-3.4.10\bin目录下运行zkserver.cmd.如下所示：

2018-11-21 17:32:36,043 [myid:] - INFO [main:Environment@100] - Server environment:java.compiler=<NA>
2018-11-21 17:32:36,045 [myid:] - INFO [main:Environment@100] - Server environment:os.name=Windows 10

3、启动完成后cmd命令下，netstat-ano查看端口监听服务。
4、cmd下进入D:\machine\zookeeper-3.4.6\bin目录下运行zkcli.cmd.如下所示：

2018-11-21 17:34:18,097 [myid:] - INFO [main:Environment@100] - Client environment:java.compiler=<NA>

安装集群伪分布模式。

1、复制 zoo.cfg 文件为zoo1.cfg 。如下所示：

# 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:\\dev\\zookeeper\\data\\d_1
dataLogDir=D:\\dev\\zookeeper\\log
# the port at which the clients will connect
clientPort=2181
server.1=localhost:2887:3887
server.2=localhost:2888:3888
server.3=localhost:2889:3889
# 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

#
# 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

2、复制 zoo1.cfg 文件为zoo2.cfg 。如下所示：

# 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:\\dev\\zookeeper\\data\\d_2
dataLogDir=D:\\dev\\zookeeper\\log
# the port at which the clients will connect
clientPort=2182
server.1=localhost:2887:3887
server.2=localhost:2888:3888
server.3=localhost:2889:3889
# 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、复制 zoo1.cfg 文件为zoo3.cfg 。如下所示：

# 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

dataDir=D:\\dev\\zookeeper\\data\\d_3
dataLogDir=D:\\dev\\zookeeper\\log
# the port at which the clients will connect
clientPort=2183
server.1=localhost:2887:3887
server.2=localhost:2888:3888
server.3=localhost:2889:3889
# 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

#
# 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

4、在D:\dev\zookeeper\data 新建d_1、d_2及d_3目录
5、复制zkserver.cmd文件为zkServer-1.cmd。部分内容如下：

setlocal
call "%~dp0zkEnv.cmd"


set ZOOMAIN=org.apache.zookeeper.server.quorum.QuorumPeerMain
set ZOOCFG=..\conf\zoo1.cfg
echo on
call %JAVA% "-Dzookeeper.log.dir=%ZOO_LOG_DIR%" "-Dzookeeper.root.logger=%ZOO_LOG4J_PROP%" -cp "%CLASSPATH%" %ZOOMAIN% "%ZOOCFG%" %*


endlocal

6、复制zkserver-1.cmd文件为zkServer-2.cmd。部分内容如下：

setlocal
call "%~dp0zkEnv.cmd"


set ZOOMAIN=org.apache.zookeeper.server.quorum.QuorumPeerMain
set ZOOCFG=..\conf\zoo2.cfg
echo on
call %JAVA% "-Dzookeeper.log.dir=%ZOO_LOG_DIR%" "-Dzookeeper.root.logger=%ZOO_LOG4J_PROP%" -cp "%CLASSPATH%" %ZOOMAIN% "%ZOOCFG%" %*


endlocal

7、复制zkserver-1.cmd文件为zkServer-3.cmd。部分内容如下：

setlocal
call "%~dp0zkEnv.cmd"


set ZOOMAIN=org.apache.zookeeper.server.quorum.QuorumPeerMain
set ZOOCFG=..\conf\zoo3.cfg
echo on
call %JAVA% "-Dzookeeper.log.dir=%ZOO_LOG_DIR%" "-Dzookeeper.root.logger=%ZOO_LOG4J_PROP%" -cp "%CLASSPATH%" %ZOOMAIN% "%ZOOCFG%" %*


endlocal

8、cmd下分别运行zkserver-1.cmd报错如下：

org.apache.zookeeper.server.quorum.QuorumPeerConfig$ConfigException: Error processing ..\conf\zoo1.cfg
	at org.apache.zookeeper.server.quorum.QuorumPeerConfig.parse(QuorumPeerConfig.java:154)

9、缺少myid 文件在对应位置创建myid 文件，文件内随便写一个数字，重新启动，报如下错误：

2018-11-21 17:47:14,624 [myid:1] - WARN [WorkerSender[myid=1]:QuorumCnxManager@588] - Cannot open channel to 2 at election address localhost/127.0.0.1:3888

10、这错是连接另外两个节点失败，启动其他两个节点即可。
11、cmd下netstar-ano查看端口监听情况。
12、cmd下运行zkcli.cmd -server:localhost:2181;zkcli.cmd ;-server:localhost:2182;zkcli.cmd -server:localhost:2183.

Windows 下 Zookeeper 单机模式和伪分布式模式安装

安装单机模式。
