获取zookeeper-3.4.9.tar.gz安装包：
1、创建 /usr/local/services/zookeeper 文件夹：
   # mkdir -p /usr/local/services/zookeeper

2、进入到 /usr/local/services/zookeeper 目录中：
   # cd /usr/local/services/zookeeper

3、解压缩 zookeeper-3.4.9.tar.gz：
拷贝文件zookeeper-3.4.9.tar.gz至/home/nriet/software目录下
# cp zookeeper-3.4.9.tar.gz/usr/local/services/zookeeper/
# tar -zxvf zookeeper-3.4.9.tar.gz

4、进入到/usr/local/services/zookeeper/zookeeper-3.4.9/conf 目录中：
    #cd zookeeper-3.4.9/conf/

5、复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg：
   # cp zoo_sample.cfg zoo.cfg

6、用 vim 打开zoo.cfg 文件并修改其内容为如下：
    # The number ofmilliseconds of each tick

    # zookeeper 定义的基准时间间隔，单位：毫秒
    tickTime=2000

    # The number ofticks that the initial
    #synchronization phase can take
    initLimit=10
    # The number ofticks that can pass between
    # sending arequest and getting an acknowledgement
    syncLimit=5
    # the directorywhere the snapshot is stored.
    # do not use/tmp for storage, /tmp here is just
    # examplesakes.
    #dataDir=/tmp/zookeeper

    # 数据文件夹
   dataDir=/usr/local/services/zookeeper/zookeeper-3.4.9/data

    # 日志文件夹
   dataLogDir=/usr/local/services/zookeeper/zookeeper-3.4.9/logs

    # the port atwhich the clients will connect
    # 客户端访问 zookeeper 的端口号
    clientPort=2181

    # the maximumnumber of client connections.
    # increase thisif you need to handle more clients
   #maxClientCnxns=60
    #
    # Be sure toread the maintenance section of the
    # administratorguide before turning on autopurge.
    #
    #http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
    #
    # The number ofsnapshots to retain in dataDir
   #autopurge.snapRetainCount=3
    # Purge taskinterval in hours
    # Set to"0" to disable auto purge feature
   #autopurge.purgeInterval=1

7、保存并关闭 zoo.cfg 文件:
   
8、进入到/usr/local/services/zookeeper/zookeeper-3.4.9/bin 目录中：

9、用 vim 打开 /etc/ 目录下的配置文件 profile：
    # vim /etc/profile
    并在其尾部追加如下内容：

    # idea -zookeeper-3.4.9 config start - 2017-11-01
    export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.9/
    export PATH=$ZOOKEEPER_HOME/bin:$PATH
    export PATH
    # idea -zookeeper-3.4.9 config start - 2017-11-01

10、使 /etc/ 目录下的profile 文件即可生效：
    # source /etc/profile

11、启动 zookeeper 服务：
    # zkServer.sh start
    如打印如下信息则表明启动成功：
    ZooKeeper JMXenabled by default
    Using config:/usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
    Startingzookeeper ... STARTED

12、查询 zookeeper 状态：
# zkServer.sh status      

                     

13、关闭 zookeeper 服务：
    # zkServer.sh stop
    如打印如下信息则表明成功关闭：
   

14、重启 zookeeper 服务：
    # zkServer.sh restart
    如打印如下信息则表明重启成功：
