    安装

    解压zookeeper-3.4.13.tar.gz ,配置环境变量

    配置

    conf/zoo.cfg配置:

    # 时间单元,其他的时间都是以此为单元
    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=/root/javaApp/zookeeper-3.4.13/dataDir
    dataLogDir=/root/javaApp/zookeeper-3.4.13/dataLogDir
    # 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
    

    开启 ./zkServer.sh

    打开命令行 ./zkCli.sh

    cZxid = 0x0    节点id
    ctime = Thu Jan 01 08:00:00 CST 1970  节点创建时间
    mZxid = 0x0      节点修改的id
    mtime = Thu Jan 01 08:00:00 CST 1970节点修改时间
    pZxid = 0x0            子节点id
    cversion = -1        子节点版本
    dataVersion = 0   此节点数据版本
    aclVersion = 0    权限的版本
    ephemeralOwner = 0x0    是0x0是永久节点,不是0x0就是临时节点
    dataLength = 0     数据长度
    numChildren = 1   子节点数量
