zookeeper的安裝和啟動

　　最近的手上一個項目要用到dubbo,順便研究下zookeeper

1、下載

　　下載地址：http://www.apache.org/dyn/closer.cgi/zookeeper/ ，下載解壓到D:\tools 如下圖所示：

2、啟動

　　進入bin文件夾下，如下圖：

3、運行(windows環境)

　　雙擊zkServer.cmd，發現閃退

4、問題解決

　　打開zkServer.cmd進行編輯，在尾部加pause,如下圖：

保存，再次雙擊，發現找不到zoo.cfg文件，如下圖：

進入conf文件夾下，將zoo_sample.cfg文件復制一份修改為zoo.cfg,如下圖：

修改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=D:/tools/zookeeper-3.4.9/data
# 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

　　至此ZooKeeper在Windows操作系統中安裝配置完畢，但需要指出的是ZooKeeper是使用java編寫的，因此運行ZooKeeper之前必須安裝Java環境——配置JDK，且JDK的版本要大於或等於1.6。

5、再次啟動

　　雙擊zkServer.cmd,出現如下界面，則啟動成功
