zookeepr 單機偽叢集配置

1. 要在單機下搭建群集，簡單的就是分別解壓複製N個目錄。

2. 每個目錄，分配配置對應的data 和 myid ，其中myid 用來表明當前啟動是哪個zookeeper

3. 設定檔的群集屬性

server.1=127.0.0.1:2881:3881
server.2=127.0.0.1:2882:3883
server.3=127.0.0.1:2883:3883
server.4=127.0.0.1:2884:3884
server.5=127.0.0.1:2885:3885

4. （我被坑的地方）每個zookeeper 服務有三個連接埠，clientPort=2181,這個用於指明給用戶端應用串連的端

（例如java 程式訪問就是這個連接埠）

    server.1=127.0.0.1:2881:3881 ，其中2881 用於群集間的伺服器進行資料通訊，3881 用於群集剛啟動時 

或leader 當機時 進行選舉。

完整的設定檔（單機環境，5個執行個體的連接埠都要不一樣）

# 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:/data/zookeeper/server5/data
# the port at which the clients will connect
clientPort=2185
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
