配置zookeeper

上传zookeeper安装包到集群中的任意一台机器上

解压tar -zxvf zookeeper-3.4.5.tar.gz

切换到zookeeper下的conf目录

 cd /home/hduser/zookeeper/zookeeper-3.5.6/conf

编辑zoo.cfg文件

  mv zoo_sample.cfg zoo.cfg
  vi zoo.cfg

     dataDir=/home/hduser/zookeeper/zookeeper-3.5.6/data  #修改数据存放的目录
     server.1=slave01:2888:3888
     server.2=slave02:2888:3888
     server.3=slave03:2888:3888

创建数据存放目录，并创建myid文件

  mkdir /home/hduser/zookeeper/zookeeper-3.5.6/data
  cd /home/hduser/zookeeper/zookeeper-3.5.6/data
  echo 1 > myid

把zookeeper安装文件夹发送到集群的其他机器

  scp -r /home/hduser/zookeeper/ hdsuer@salve02:/home/hduser/zookeeper
  scp -r /home/hduser/zookeeper/ hdsuer@slave03:/home/hduser/zookeeper

修改其他机器上的myid

 ……
 echo 2 > myid
 echo 3 > myid

分别启动zookeeper

 cd /home/hduser/zookeeper/zookeeper-3.5.6/bin
 ./zkServer.sh start

查看进程 jps

查看zookeeper状态

  ./zkServer.sh status
