ZooKeeper 是什麼？
ZooKeeper是一個分散式的，開放原始碼的分散式應用程式協調服務，是Google的Chubby一個開源的實現，是Hadoop和Hbase的重要元件。它是一個為分散式應用提供一致性服務的軟體，提供的功能包括：配置維護、域名服務、分散式同步、組服務等。
ZooKeeper的目標就是封裝好複雜易出錯的關鍵服務，將簡單易用的介面和效能高效、功能穩定的系統提供給使用者。
ZooKeeper包含一個簡單的原語集，提供Java和C的介面。
ZooKeeper程式碼版本中，提供了分散式獨享鎖、選舉、佇列的介面，程式碼在zookeeper-3.4.8\src\recipes。其中分佈鎖和佇列有Java和C兩個版本，選舉只有Java版本。

解壓到E:\zookeeper-3.4.13\zookeeper-3.4.13
修改配置檔案
複製zoo_sample.cfg 檔名(E:\zookeeper-3.4.13\zookeeper-3.4.13\conf) 為 zoo.cfg
主要修改一下日誌位置，具體配置檔案如下：
# 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=E:\\zookeeper\\data dataLogDir=E:\\zookeeper\\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
配置檔案簡單解析
1、tickTime：這個時間是作為 Zookeeper 伺服器之間或客戶端與伺服器之間維持心跳的時間間隔，也就是每個 tickTime 時間就會發送一個心跳。
2、dataDir：顧名思義就是 Zookeeper 儲存資料的目錄，預設情況下，Zookeeper 將寫資料的日誌檔案也儲存在這個目錄裡。
3、dataLogDir：顧名思義就是 Zookeeper 儲存日誌檔案的目錄
4、clientPort：這個埠就是客戶端連線 Zookeeper 伺服器的埠，Zookeeper 會監聽這個埠，接受客戶端的訪問請求。
開啟powershell 檢視一下zookeeper的整體目錄

PS E:\zookeeper-3.4.13> ls

簡單介紹連個目錄：
bin：可執行指令碼
conf：配置檔案（剛才已經在conf做了一個簡單的配置）
如何啟動zookeeper呢？
執行指令碼需要進入bin
PS E:\zookeeper-3.4.13\zookeeper-3.4.13> cd bin
PS E:\zookeeper-3.4.13\zookeeper-3.4.13\bin> ls
目錄: E:\zookeeper-3.4.13\zookeeper-3.4.13\bin

可以看到在bin的下面既有sh，又有cmd，說明zookeeper支援linux和win兩類系統
啟動一下試試：
PS E:\zookeeper-3.4.13\zookeeper-3.4.13\bin> .\zkServer.cmd
使用zkCli.cmd 客戶端連線zookeeper報錯
PS E:\zookeeper-3.4.13\zookeeper-3.4.13\bin> .\zkCli.cmd 127.0.0.0.1:2181

解決辦法：
1、換低版本
2、此版本沒有找到很好的解決方案。。。待續
另一種方法：
PS E:\zookeeper-3.4.13\zookeeper-3.4.13\bin> jps -l -v
17828 sun.tools.jps.Jps -Dapplication.home=C:\Program Files\Java\jdk1.8.0_161 -Xms8m
25004 org.apache.zookeeper.server.quorum.QuorumPeerMain -Dzookeeper.log.dir=E:\zookeeper-3.4.13\zookeeper-3.4.13\bin\.. -Dzookeeper.root.logger=INFO,CONSOLE
可以看到QuorumPeerMain的程序
