#### 基础环境 ####

--------------------

centos7.5 + zookeeper-3.4.6

#### 步骤 ####

--------------------

1.  下载zookeeper-3.4.6.tar.gz
2.  解压缩到自己项目目录
    
        tar -zxvf zookeeper-3.4.6.tar.gz
        mv zookeeper-3.4.6 /usr/local/services/zookeeper  #更改为自己的项目目录
3.  配置启动文件
    
        cd /usr/local/services/zookeeper/conf
        cp zoo_sample.cfg zoo.cfg     #复制配置样本到我们自己的配置文件
        
        vim zoo.cfg
        
        >>>
            # 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
            # 数据文件夹
            dataDir=/usr/local/services/zookeeper/data
            # 日志文件夹
            dataLogDir=/usr/local/services/zookeeper/logs	   #要手动创建这个文件夹，否则会出错
            # 客户端访问 zookeeper 的端口号
            clientPort=2181
4.  配置环境变量
    
        vim /etc/profile
        
        >>>>追加
            export ZOOKEEPER_HOME=/usr/local/services/zookeeper/
            export PATH=$ZOOKEEPER_HOME/bin:$PATH
            export PATH
        
        # 使文件生效
        source /etc/profile
5.  启动服务
    
        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/bin/../conf/zoo.cfg
        Starting zookeeper ... STARTED
6.  查看服务状态
    
        zkServer.sh status
7.  关闭服务
    
        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-3.4.9/bin/../conf/zoo.cfg
        Stopping zookeeper ... STOPPED
8.  重启服务
    
        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-3.4.9/bin/../conf/zoo.cfg
        ZooKeeper JMX enabled by default
        Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
        Stopping zookeeper ... STOPPED
        ZooKeeper JMX enabled by default
        Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
        Starting zookeeper ... STARTED
