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 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"
