在docker中安装Hadoop

 tar -xzvf zookeeper-3.4.11.tar.gz
/opt/zookeeper-3.4.12
配置环境变量
vim /etc/profilve
        # 添加如下内容
        export ZOOKEEPER_HOME = /opt/zookeeper-3.4.12
        export PATH = $PATH:$ZOOKEEPER_HOME/bin
配置zookeeper集群，修改配置文件      
    cp /opt/zookeeper/conf/zoo_sample.cfg /opt/zookeeper/conf/zoo.cfg
        # 5.1 在zoo.cfg 文件末尾追加（zoo1 为 服务器名称）
        # 具体配置见：http://zookeeper.apache.org/doc/r3.4.11/zookeeperStarted.html#sc_RunningReplicatedZooKeeper
        tickTime=2000
        dataDir=/opt/data/zookeeper # 数据存放路径
        clientPort=2181
        initLimit=5
        syncLimit=2
        server.1=node2:2888:3888
        server.2=node3:2888:3888
        server.3=node4:2888:3888
将配置文件复制到其他节点
   scp /opt/zookeeper/conf/zoo.cfg node2:/opt/zookeeper/conf/  
创建节点ID，在配置的 dataDir 路径中添加myid文件
   cho "1" > myid         


1. 启动ZK服务:       sh bin/zkServer.sh start
2. 查看ZK服务状态:   sh bin/zkServer.sh status
3. 停止ZK服务:       sh bin/zkServer.sh stop
4. 重启ZK服务:       sh bin/zkServer.sh restart
