## 下载zookeeper ##

**下载地址：**[https://www.apache.org/dyn/closer.cgi/zookeeper/][https_www.apache.org_dyn_closer.cgi_zookeeper]

下载下来zookeeper-3.4.11.tar.gz，解压到当前文件夹

## 修改配置 ##

**找到zookeeper-3.4.11\\conf\\zoo\_sample.cfg，修改为zoo.cfg.打开配置文件，修改：**

# 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.
    
    # 修改dataDir、新增dataLogDir，其他的不变
    dataDir=E:\zookeeper-3.4.11\data
    dataLogDir=E:\zookeeper-3.4.11\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

## 启动zookeeper ##

**进入E:\\zookeeper-3.4.11\\bin，cmd打开dos**

zkServer.cmd

## 解决可能出现的问题 ##

**问题：JAVA\_HOME is not set.**  
**解决：打开E:\\zookeeper-3.4.11\\bin\\zkEnv.cmd,如下：**

    REM for sanity sake assume Java 1.6
    REM see: http://java.sun.com/javase/6/docs/technotes/tools/windows/java.html
    
    REM add the zoocfg dir to classpath
    set CLASSPATH=%ZOOCFGDIR%
    
    REM make it work in the release
    SET CLASSPATH=%~dp0..\*;%~dp0..\lib\*;%CLASSPATH%
    
    REM make it work for developers
    SET CLASSPATH=%~dp0..\build\classes;%~dp0..\build\lib\*;%CLASSPATH%
    
    set ZOOCFG=%ZOOCFGDIR%\zoo.cfg
    
    @REM setup java environment variables
    
    if not defined JAVA_HOME (
      echo Error: JAVA_HOME is not set.
      goto :eof
    )
    
    set JAVA_HOME=%JAVA_HOME:"=%
    
    if not exist "%JAVA_HOME%"\bin\java.exe (
      echo Error: JAVA_HOME is incorrectly set.
      goto :eof
    )
    
    set JAVA="%JAVA_HOME%"\bin\java

**出现原因：在Windows下java默认安装装在C:\\Program Files\\Java\\jdk1.xxx下，路径中存在空格，启动时会找不到正确的路径，在JAVA\_HOME上加”“即可。**

**修改为如下信息：**

if not exist "%JAVA_HOME%\bin\java.exe" (
      echo Error: JAVA_HOME is incorrectly set.
      goto :eof
    )
    
    set JAVA="%JAVA_HOME%\bin\java"
