安装（伪集群模式）过程

1. 解压：tar -zxvf zookeeper-3.4.5.tar.gz
   
2. 配置文件：在conf目录下删除zoo_sample.cfg文件，创建一个配置文件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.
   dataDir=/home/jiangconglin/zk/data
   # the port at which the clients will connect
   clientPort=2187
   
   dataLogDir=/home/jiangconglin/zk/dataLog
   
   server.0=127.0.0.1:8880:3387    
   server.1=127.0.0.1:8881:3388    
   server.2=127.0.0.1:8882:3389 

   
   
3. 配置文件：创建一个配置文件zoo1.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.
   dataDir=/home/jiangconglin/zk/data1
   # the port at which the clients will connect
   clientPort=2188
   
   dataLogDir=/home/jiangconglin/zk/dataLog1
   
   server.0=127.0.0.1:8880:3387    
   server.1=127.0.0.1:8881:3388    
   server.2=127.0.0.1:8882:3389

   
   
   
4. 配置文件：创建一个配置文件zoo2.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.
   dataDir=/home/jiangconglin/zk/data2
   # the port at which the clients will connect
   clientPort=2189
   
   dataLogDir=/home/jiangconglin/zk/dataLog2
   
   server.0=127.0.0.1:8880:3387    
   server.1=127.0.0.1:8881:3388    
   server.2=127.0.0.1:8882:3389

5. 创建myid
   在dataDir(/home/jiangconglin/zk/data|1|2)目录创建myid文件
   Server0机器的内容为：0
   Server1机器的内容为：1
   Server2机器的内容为：2
   
6. 创建日志目录
   /home/jiangconglin/zk/dataLog
   /home/jiangconglin/zk/dataLog1
   /home/jiangconglin/zk/dataLog2
