windows环境下安装Zookeper

刚学习Zookeper时大多数都是直接在windows环境下安装，本文主要介绍Zookeper安装启动及注意事项，由于Zookeper需要在java环境运行，启动之前配置好java环境变量
1.下载Zookeper
链接：https://pan.baidu.com/s/1tsU3-FI0_k48e9dBY0TDmQ
提取码：t2nn
2.解压文件到本地，一下为Zookeper文件目录

3.创建data、log两个文件夹用于存储数据与日志信息

4.进入conf文件复制zoo_sample.cfg并命名为zoo.cfg

5.zoo.cfg默认配置为一下信息

# 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=/tmp/zookeeper
# 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

6 编辑配置信息，修改dataDir的值，指向刚才创建的data文件夹，同时创建一个dataLogDir，指向上一次创建的log文件夹，修改后为

# 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/development/zookeeper-3.4.12/zookeeper-3.4.12/data 
dataLogDir=D:/development/zookeeper-3.4.12/zookeeper-3.4.12/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

两次对比

7.进入Zookeper主目录下打开bin目录，会看到以下文件

zkServer.cmd为windows环境下服务端启动命令
编辑zkServer.cmd，需要修改启动命令，下面为启动脚本，直接启动DOS会直接闪退，因为这个脚本需要做一些修改

a）在结尾之前需要指定Zookeper配置文件路径，我的路径配置如下，只需要将路径改为对应的zoo.cfg路径

set ZOOCFG=D:/development/zookeeper-3.4.12/zookeeper-3.4.12/conf/zoo.cfg

b）启动依然报错，添加一个暂停，启动zkServer.cmd查看错误信息


日志提示是因为Zookeper需要在环境变量中配置JAVA变量，可能很多人直接将path中添加的环境，这样 call ‘%jJAVA%’ 找不到对应的变量值，直接将call "%JAVA%"改成java，直接执行java命令，这样只要配置了java环境变量就可使用

执行server启动脚本，出现以下画面，则Zookeper启动完成

8.启动客户端，若出现闪退，修改脚本

9.启动客户端，Zookeper安装启动完成
