 ./zkServer.sh  [start|start-foreground|stop|restart|status|upgrade|print-cmd]

　　1、将conf下的zoo_sample.cfg修改配置为zoo.cfg

      2、tickTime：默认2000ms，作为基本单元，用它的配属来表示系统内部的时间间隔配置，比如：

             2*tickTime是客户端回话的超时时间

             1*tickTime是客户端与zk服务器端的心跳时间

      dataDir：用于配置存储快照文件的目录，如果没有配置dataLogDir，事务日志也会存储在该目录【需要配置】，一般创建data文件夹

      dataLogDir：事务日志母了路径，一般在zookeeper下创建logs文件夹

      clientPort：zk的运行端口，默认2181
