ZOOKEEPER安装

ZOOKEEPER安装

1. 查看是否安装了zookeeper：rpm -qa | grep zookeeper；如果安装了那么继续使用或者卸载：yum remove zookeeper_name
2. 下载zookeeper：wget http://www-eu.apache.org/dist/zookeeper/stable/zookeeper-3.4.12.tar.gz
3. 安装zooleeper：tar -zxvf zookeeper-3.4.10.tar.gz
4. 进入zookeeper文件夹中的conf：cd zookeeper-3.4.12/conf/；进入conf文件
5. 复制一份副本，重命名文件名为zoo.cfg：cp zoo_sample.cfg zoo.cfg
6. 修改conf文件：vi zoo.cfg

7. 修改内容为
   # 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=/home/zero/soft/zookeeper/zookeeper-3.4.10/data
   
      # 日志文件夹
      dataLogDir=/home/zero/soft/zookeeper/zookeeper-3.4.10/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
   

8. 设置环境变量：vi /etc/profile;修改环境变量值为（修改完后要使配置文件生效：source /etc/profile）：
   # zookeeper-3.4.10 config start - 2018-09-13
   # ZOOKEEPER_HOME：安装目录
   export ZOOKEEPER_HOME=/home/zero/sfot/zookeeper/zookeeper-3.4.10/
   export PATH=$ZOOKEEPER_HOME/bin:$PATH
   export PATH
9. 启动服务端：./zkServer.sh start；关闭：./zkServer.sh stop；重启：./zkServer restart
