一、描述  
伪分布式集群就是在一台机器部署多个zk应用，部署之前服务器需要有jdk环境 java -version可以显示相关java信息才可以进行zookeeper搭建  
二.步骤

> 第一步下载好zookeeper-3.4.9.tar.gz  
> 然后解压 tar zxvf zookeeper-3.4.9.tar.gz  
> ![这里写图片描述][70]  
> 进入zk中的conf目录下输入cp zoo-sample.cfg zoo1.cfg cp zoo-sample.cfg zoo2.cfg、cp zoo-sample.cfg zoo3.cfg  
> 分别对zoo1、2、3文件进行编辑

# 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=/apps/servers/data/d_1
    dataLogDir=/apps/servers/logs/logs_1
    # the port at which the clients will connect
    clientPort=2181 
    #不同zoo.cfg修改自己的属性和端口号
    # 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
    server.1=localhost:2187:2887 
    server.2=localhost:2188:2888
    server.3=localhost:2189:2889

> 修改之后分别创建data目录和日志目录

mkdir /apps/servers/data/d_1
    Mkdir /apps/servers/data/d_1
    mkdir /apps/servers/data/d_1
    
    mkdir /apps/servers/logs/logs_1
    mkdir /apps/servers/logs/logs_1
    mkdir /apps/servers/logs/logs_1
    
    echo "1" > /apps/servers/data/d_1/myid
    echo "2" >/apps/servers/data/d_2/myid
    echo "3" >/apps/servers/data/d_3/myid

> 进入bin目录下输入命令 分别进行启动

zkServer.sh start ../conf/zoo1.cfg
    zkServer.sh start ../conf/zoo2.cfg
    zkServer.sh start ../conf/zoo3.cfg

通过命令检测是否成功：

zkCli.sh -server localhost:2181, 
    localhost:2182, localhost:2183 是否可以连接成功
