1.源自http://zookeeper.apache.org

    1.1從映象網站下載安裝包。

            url:http://mirrors.shu.edu.cn/apache/zookeeper/zookeeper-3.3.6/ 這是3.3.6版本的

            也可以進入https://www.apache.org/dyn/closer.cgi/zookeeper/  自己選擇映象，然後選擇版本

    1.2解壓

            可以使用命令，如果未安裝工具的情況下tar -zxvf 檔案包 -C 指定路徑

    1.3 改配置

            http://zookeeper.apache.org/doc/r3.4.11/zookeeperStarted.html#sc_Download 這裡有提到

            To start ZooKeeper you need a configuration file. Here is a sample, create it in conf/zoo.cfg:

                tickTime=2000
                dataDir=/var/lib/zookeeper
                clientPort=2181

            那就在解壓後的conf路徑下增加這個檔案，或者直接將zoo_sample.cfg改名為zoo.cfg,引數解析

This file can be called anything, but for the sake of this discussion call it conf/zoo.cfg

tickTime

the basic time unit in milliseconds used by ZooKeeper. It is used to do heartbeats and the minimum session timeout will be twice the tickTime.

dataDir

the location to store the in-memory database snapshots and, unless specified otherwise, the transaction log of updates to the database.

clientPort

the port to listen for client connections

       不一一翻譯了，dataDir這個儲存日誌和資料庫快照等，路徑請先建立好

    1.3 啟動

             ./zkServer.sh start

    1.4 連線        

            ./zkCli.sh -server 127.0.0.1:2181

    1.5 連線
