在 CentOS7 上安装 zookeeper-3.4.9 服务

  在 CentOS7 上安装 zookeeper- 3.4 . 9  服务 
 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 、下载 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 、解压缩 zookeeper- 3.4 . 9 .tar.gz： 
      tar -zxvf zookeeper- 3.4 . 9 .tar.gz 
 5 、进入到 /usr/local/services/zookeeper/zookeeper- 3.4 . 9 /conf 目录中： 
      cd zookeeper- 3.4 . 9 /conf/ 
 6 、复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg： 
      cp zoo_sample.cfg zoo.cfg 
 7 、用 vim 打开 zoo.cfg 文件并修改其内容为如下： 
      # The number of milliseconds of each tick 
      # zookeeper 定义的基准时间间隔，单位：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 
      # 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 at which the clients will connect 
      # 客户端访问 zookeeper 的端口号 
      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 、保存并关闭 zoo.cfg 文件: 
       
 9 、进入到 /usr/local/services/zookeeper/zookeeper- 3.4 . 9 /bin 目录中： 
      cd ../bin/ 
 10 、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 -  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/ 目录下的 profile 文件即可生效： 
      source /etc/profile 
 12 、启动 zookeeper 服务： 
      zkServer.sh start 
      如打印如下信息则表明启动成功： 
      ZooKeeper JMX enabled by  default 
      Using config: /usr/local/services/zookeeper/zookeeper- 3.4 . 9 /bin/../conf/zoo.cfg 
      Starting zookeeper ... STARTED 
 13 、查询 zookeeper 状态： 
      zkServer.sh status 
 14 、关闭 zookeeper 服务： 
      zkServer.sh stop 
      如打印如下信息则表明成功关闭： 
      ZooKeeper JMX enabled by  default 
      Using config: /usr/local/services/zookeeper/zookeeper- 3.4 . 9 /bin/../conf/zoo.cfg 
      Stopping zookeeper ... STOPPED 
 15 、重启 zookeeper 服务： 
      zkServer.sh restart 
      如打印如下信息则表明重启成功： 
      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
