tickTime：心跳间隔时间，单位毫秒，默认值2000。用来设置zookeeper与客户端之间，以及zookeeper集群内部节点之间的心跳间隔时间。
initLimit：初始化时，leader服务和follower服务之间可以无心跳的数量，默认是10。初始化时，如果到了20S，还没收到一个心跳，就认为本次初始化失败。这个值依赖tickTime的值。
syncLimit：leader服务和follower服务之间请求响应的最大间隔，默认值5，也就是10S。这个值依赖tickTime的值。
dataDir：zookeeper存储自身数据的目录，默认/tmp/zookeeper，不建议这个目录。
clientPort：zookeeper服务监听的端口。
