在 CentOS7 上安装 zookeeper-3.4.10 服务

1、创建 /usr/local/services/zookeeper 文件夹：
        mkdir -p /usr/local/services/zookeeper
    
    2、进入到 /usr/local/services/zookeeper 目录中：
        cd /usr/local/services/zookeeper
    
    3、下载 zookeeper-3.4.10.tar.gz：
        wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz
    
    4、解压缩 zookeeper-3.4.10.tar.gz：
        tar -zxvf zookeeper-3.4.10.tar.gz
    
    5、进入到 /usr/local/services/zookeeper/zookeeper-3.4.10/conf 目录中：
        cd zookeeper-3.4.10/conf/
    
    6、复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg：
        cp zoo_sample.cfg zoo.cfg
    
    7、用 vim 打开 zoo.cfg 文件并修改其内容为如下：
        # 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=/usr/local/services/zookeeper/zookeeper-3.4.10/data
    
        # 日志文件夹
        dataLogDir=/usr/local/services/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
        # Set to "0" to disable auto purge feature
        #autopurge.purgeInterval=1
    
    8、保存并关闭 zoo.cfg 文件:
    
    9、进入到 /usr/local/services/zookeeper/zookeeper-3.4.10/bin 目录中：
        cd ../bin/
    
    10、用 vim 打开 /etc/ 目录下的配置文件 profile：
        vim /etc/profile
        并在其尾部追加如下内容：
    
        # idea - zookeeper-3.4.10 config start - 2016-09-08
    
        export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.10/
        export PATH=$ZOOKEEPER_HOME/bin:$PATH
        export PATH
    
        # idea - zookeeper-3.4.10 config start - 2016-09-08
    
    11、使 /etc/ 目录下的 profile 文件即可生效：
        source /etc/profile
    
    12、启动 zookeeper 服务：
        zkServer.sh start
        如打印如下信息则表明启动成功：
        ZooKeeper JMX enabled by default
        Using config: /usr/local/services/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg
        Starting zookeeper ... STARTED
    
    13、查询 zookeeper 状态：
        zkServer.sh status
    
    14、关闭 zookeeper 服务：
        zkServer.sh stop
        如打印如下信息则表明成功关闭：
        ZooKeeper JMX enabled by default
        Using config: /usr/local/services/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg
        Stopping zookeeper ... STOPPED
    
    15、重启 zookeeper 服务：
        zkServer.sh restart
        如打印如下信息则表明重启成功：
        ZooKeeper JMX enabled by default
        Using config: /usr/local/services/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg
        ZooKeeper JMX enabled by default
        Using config: /usr/local/services/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg
        Stopping zookeeper ... STOPPED
        ZooKeeper JMX enabled by default
        Using config: /usr/local/services/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg
        Starting zookeeper ... STARTED
