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

  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
