Centos7 搭建Zookeeper集群 一般步骤：

第一步：zookeeper 下载地址
    https://www-eu.apache.org/dist/zookeeper/stable/
    
    第二步：解压zookeeper
    tar -xzvf zookeeper-3.5.6.tar.gz
    
    第三步：配置zookeeper 全局环境变量
    vi /etc/profile
    
    在文件中添加如下内容：
    export ZOOKEEPER_HOME=/usr/local/zookeeper/apache-zookeeper-3.5.6
    export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$ZOOKEEPER_HOME/bin:$PATH
    
    第四步：修改zookeeper 配置文件
    cp /usr/local/zookeeper/apache-zookeeper-3.5.6/conf/zoo_sample.cfg /usr/local/zookeeper/apache-zookeeper-3.5.6/conf/zoo.cfg
    
    vi /usr/local/zookeeper/apache-zookeeper-3.5.6/conf/zoo.cfg
    
    编辑内容如下：
    # The number of milliseconds of each tick
    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=/usr/local/zookeeper/data/data
    dataLogDir=/uar/local/zookeeper/data/logs
    # the port at which the clients will connect
    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
    server.1=elk-server:2888:3888
    server.2=node1:2888:3888
    
    相关说明：
    dataDir: zookeeper 数据存储地址
    dataLogDir: zookeeper 日志文件存储地址
    
    第五步：复制elk-server节点上的zookeeper-3.5.6文件夹至node1 节点上
    scp /usr/local/zookeeper/apache-zookeeper-3.5.6 node1:/usr/local/zookeeper/apache-zookeeper-3.5.6
    
    第六步：分别编辑elk-server 和node1 的myid
    elk-server 虚拟机：
    在dataDir=/usr/local/zookeeper/data/data目录下创建空文件
    touch /usr/local/zookeeper/data/data/myid  
    echo 1 > /usr/local/zookeeper/data/data/myid  
    
    node1 虚拟机：
    在dataDir=/usr/local/zookeeper/data/data目录下创建空文件
    touch /usr/local/zookeeper/data/data/myid  
    echo 2 > /usr/local/zookeeper/data/data/myid
    
    第七步：zookeeper 日志文件修改
    编辑/usr/local/zookeeper/apache-zookeeper-3.5.6/conf/zkEnv.sh 文件
    vi /usr/local/zookeeper/apache-zookeeper-3.5.6/conf/zkEnv.sh
    
    修改如下内容：
    if [ "x${ZOO_LOG_DIR}" = "x" ]
    then
        # 服务运行日志输出路径
        ZOO_LOG_DIR="/uar/local/zookeeper/data/logs"
    fi
    
    if [ "x${ZOO_LOG4J_PROP}" = "x" ]
    then
        ZOO_LOG4J_PROP="INFO,ROLLINGFILE"
    fi
    
    第八步：zookeeper 服务启动和状态
    切换至zookeeper 文件夹下的bin 目录
    cd /usr/local/zookeeper/apache-zookeeper-3.5.6/bin
    
    启动zookeeper 
    ./zkServer.sh start
    
    zookeeper 状态信息
    ./zkServer.sh status
    
    [root@elk-server bin]# ./zkServer.sh start
    ZooKeeper JMX enabled by default
    Using config: /usr/local/zookeeper/apache-zookeeper-3.5.6/bin/../conf/zoo.cfg
    Starting zookeeper ... STARTED
    [root@elk-server bin]# ./zkServer.sh status
    ZooKeeper JMX enabled by default
    Using config: /usr/local/zookeeper/apache-zookeeper-3.5.6/bin/../conf/zoo.cfg
    Client port found: 2181. Client address: localhost.
    Mode: follower

在启动zookeeper 时，提示如下错误：org.apache.zookeeper.server.quorum.QuorumPeerMain

解决办法：下载一个zookeeper带bin后缀的文件，因为改文件中包含lib 文件夹，将这个lib 文件夹拷贝至当前zookeeper-3.5.6 的安装目录.
