在 CentOS7 上安裝 zookeeper-3.4.9 服務
 
1、建立 /usr/local/services/zookeeper 資料夾：
    mkdir -p /usr/local/services/zookeeper
 
2、進入到 /usr/local/services/zookeeper 目錄中：
    cd /usr/local/services/zookeeper
 
3、下載 zookeeper-3.4.9.tar.gz：
    wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz
 
4、解壓縮 zookeeper-3.4.9.tar.gz：
    tar -zxvf zookeeper-3.4.9.tar.gz
 
5、進入到 /usr/local/services/zookeeper/zookeeper-3.4.9/conf 目錄中：
    cd zookeeper-3.4.9/conf/
 
6、複製 zoo_sample.cfg 檔案的並命名為為 zoo.cfg：
    cp zoo_sample.cfg zoo.cfg
 
7、用 vim 開啟 zoo.cfg 檔案並修改其內容為如下：
    # The number of milliseconds of each tick
 
    # zookeeper 定義的基準時間間隔，單位：毫秒
    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=/tmp/zookeeper
 
    # 資料資料夾
    dataDir=/usr/local/services/zookeeper/zookeeper-3.4.9/data
 
    # 日誌資料夾
    dataLogDir=/usr/local/services/zookeeper/zookeeper-3.4.9/logs
 
    # the port at which the clients will connect
    # 客戶端訪問 zookeeper 的埠號
    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
 
8、儲存並關閉 zoo.cfg 檔案:
     
9、進入到 /usr/local/services/zookeeper/zookeeper-3.4.9/bin 目錄中：
    cd ../bin/
 
10、用 vim 開啟 /etc/ 目錄下的配置檔案 profile：
    vim /etc/profile
    並在其尾部追加如下內容：
 
    # idea - zookeeper-3.4.9 config start - 2016-09-08
 
    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 - 2016-09-08
 
11、使 /etc/ 目錄下的 profile 檔案即可生效：
    source /etc/profile
 
12、啟動 zookeeper 服務：
    zkServer.sh start
    如列印如下資訊則表明啟動成功：
    ZooKeeper JMX enabled by default
    Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
    Starting zookeeper ... STARTED
 
13、查詢 zookeeper 狀態：
    zkServer.sh status
 
14、關閉 zookeeper 服務：
    zkServer.sh stop
    如列印如下資訊則表明成功關閉：
    ZooKeeper JMX enabled by default
    Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
    Stopping zookeeper ... STOPPED
 
15、重啟 zookeeper 服務：
    zkServer.sh restart
    如列印如下資訊則表明重啟成功：
    ZooKeeper JMX enabled by default
    Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
    ZooKeeper JMX enabled by default
    Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
    Stopping zookeeper ... STOPPED
    ZooKeeper JMX enabled by default
    Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
    Starting zookeeper ... STARTED
