• 下載Zookeeper

• 解壓Zookeeper安裝包

  # tar -zxvf zookeeper-3.4.8.tar.gz
  

• 配置Zookeeper文件及日誌目錄

  • 創建保存文件及日誌的目錄

    # mkdir data
    # mkdir logs
    

  • 修改Zookeeper的配置文件

    • 將zookeeper-3.4.8/conf目錄下的zoo_sample.cfg文件拷貝一份命名爲爲zoo.cfg

      # cp zoo_sample.cfg zoo.cfg
      

    • 編輯zoo.cfg將zookeeper的dataDir和dataLogDir指向之前創建好的文件及日誌目錄

      # 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=/opt/zookeeper/data
      dataLogDir=/opt/zookeeper/logs
      
      # the port at which the clients will connect
      clientPort=2181
      
      server.1=localhost:2888:3888
      

    • 在dataDir下創建myid文件(編輯myid文件並在對應的IP的機器上輸入對應的編號)

      # echo 1 > myid
      

• 添加Zookeeper環境變量配置(修改/etc/profile添加如下配置)，並使環境變量配置生效

  ZOOKEEPER_HOME=/opt/zookeeper/zookeeper-3.4.8
  export PATH=$ZOOKEEPER_HOME/bin:$PATH
  

  # source /etc/profile
  

• 啓動並測試Zookeeper

  # 啓動Zookeeper
  zkServer.sh start
   
  # 查看Zookeeper狀態
  zkServer.sh status
   
  # 服務器輸出信息
  tail -500f zookeeper.out
   
  # 停止zookeeper
  zkServer.sh stop
  

• 設置Zookeeper服務開機啓動

  • 在/etc/rc.d/init.d添加可執行文件zookeeper

    # 切換到/etc/rc.d/init.d/目錄下
    # cd /etc/rc.d/init.d
    
    # 創建zookeeper文件
    # touch zookeeper
    
    # 將zookeeper修改爲可執行文件
    # chmod +x zookeeper
    
    # 編輯文件，在zookeeper裏面輸入如下內容
    #!/bin/bash
    #chkconfig:2345 20 90
    #description:zookeeper
    #processname:zookeeper
    export JAVA_HOME=/opt/java/jdk1.8.0_91
    export PATH=$JAVA_HOME/bin:$PATH
    case $1 in
         start) su root /opt/zookeeper/zookeeper-3.4.8/bin/zkServer.sh start;;
         stop) su root /opt/zookeeper/zookeeper-3.4.8/bin/zkServer.sh stop;;
         status) su root /opt/zookeeper/zookeeper-3.4.8/bin/zkServer.sh status;;
         restart) su root /opt/zookeeper/zookeeper-3.4.8/bin/zkServer.sh restart;;
         *) echo "require start|stop|status|restart";;
    esac
    

  • 這個時候我們就可以用service zookeeper start/stop來啓動停止Zookeeper服務了

  • 使用命令把zookeeper添加到開機啓動任務中

    # chkconfig zookeeper on
    # chkconfig --add zookeeper
    

  • 添加完成之後接這個使用chkconfig --list來看看我們添加的zookeeper是否在裏面

  • 如果上面的操作都正常的話，你就可以重啓你的Linux服務器了
