主从节点每个都要安装

准备：  
在master节点端口sftp会话窗口：

sftp> pwd
    /opt/bigdata
    sftp> put G:\zookeeper-3.4.5.tar.gz
    Uploading zookeeper-3.4.5.tar.gz to /opt/bigdata/zookeeper-3.4.5.tar.gz
      100% 16017KB  16017KB/s 00:00:00     
    G:/zookeeper-3.4.5.tar.gz: 16402010 bytes transferred in 0 seconds (16017 KB/s)
    sftp>

[root@master bigdata]# pwd
    /opt/bigdata
    [root@master bigdata]# tar zxvf zookeeper-3.4.5.tar.gz
    ..
    [root@master bigdata]# pwd
    /opt/bigdata
    [root@master bigdata]# cd zookeeper-3.4.5/conf
    ...
    
    [root@master conf]# cp zoo_sample.cfg zoo.cfg
    [root@master conf]# vi zoo.cfg
    注释掉第12行。并在末尾添加如下内容：
    
    dataDir=/opt/bigdata/zookeeper-3.4.5/data
    dataLogDir=/opt/bigdata/zookeeper-3.4.5/log
    server.1=master:2888:3888
    server.2=slave1:2888:3888
    server.3=slave2:2888:3888
    
    创建日志文件夹及数据文件夹
    [root@master conf]# cd ..
    [root@master zookeeper-3.4.5]# mkdir data
    [root@master zookeeper-3.4.5]# mkdir log
    
    配置环境变量：
    [root@master zookeeper-3.4.5]# vi /etc/profile
    
    在末尾添加如下两行
    ZOOKEEPER_HOME=/opt/bigdata/zookeeper-3.4.5
    export PATH=$PATH:$ZOOKEEPER_HOME/bin
    
    
    重新加载环境变量
    [root@master zookeeper-3.4.5]# source /etc/profile
    
    复制Zookeeper包到从节点
    [root@master zookeeper-3.4.5]# scp -r /opt/bigdata/zookeeper-3.4.5 root@slave1:/opt/bigdata/zookeeper-3.4.5
    
    [root@master zookeeper-3.4.5]# scp -r /opt/bigdata/zookeeper-3.4.5 root@slave2:/opt/bigdata/zookeeper-3.4.5
    
    在两个从节点上，修改环境变量并重新加载环境变量
    vi /etc/profile
    source /etc/profile
    
    分别添加ID，每一个节点的id都不能重复且需与配置文件一致
    #Master
    echo "1" > /usr/local/src/zookeeper-3.4.11/data/myid
    #Slave1
    echo "2" > /usr/local/src/zookeeper-3.4.11/data/myid
    #Slave2
    echo "3" > /usr/local/src/zookeeper-3.4.11/data/myid
    
    
    
    # 启动Zookeeper服务 (【每个节点】都要启动)
    [root@master zookeeper-3.4.5]# zkServer.sh start
    JMX enabled by default
    Using config: /opt/bigdata/zookeeper-3.4.5/bin/../conf/zoo.cfg
    Starting zookeeper ... STARTED
    
    查看运行状态
    [root@master zookeeper-3.4.5]# zkServer.sh status
    JMX enabled by default
    Using config: /opt/bigdata/zookeeper-3.4.5/bin/../conf/zoo.cfg
    Mode: follower
    
    [root@slave1 slave1]# zkServer.sh status
    JMX enabled by default
    Using config: /opt/bigdata/zookeeper-3.4.5/bin/../conf/zoo.cfg
    Mode: leader
    
    [root@slave2 slave2]# zkServer.sh status
    JMX enabled by default
    Using config: /opt/bigdata/zookeeper-3.4.5/bin/../conf/zoo.cfg
    Mode: follower
    
    
    # 查看服务进程
    3个节点都有QuorumPeerMain
    即可。
    [root@master zookeeper-3.4.5]# jps
    30455 Jps
    28808 SecondaryNameNode
    28667 NameNode
    28955 ResourceManager
    30398 QuorumPeerMain
    
    [root@slave1 slave1]# jps
    10144 NodeManager
    10514 QuorumPeerMain
    10072 DataNode
    10570 Jps
    
    [root@slave2 slave2]# jps
    26322 NodeManager
    26233 DataNode
    26666 QuorumPeerMain
    26716 Jps
    
    关闭：zkServer.sh stop
