// -s 附加次级信息 -w 监听子节点变化
ls -s ///普通创建
//-s 含有序列 -e 临时重启或超时消失
create 节点路径//获得节点的值
// -s 附加次级信息 -w 监听节点内容变化
get 节点路径//设置节点值
set 节点路径 新值//查看节点状态
stat//删除节点 当前节点没有子节点才能删除成功
delete 节点路径//递归删除节点 当前节点含有子节点
deleteall 节点路径监听节点的差异同样都是删除子节点两种命令是不一样的

节点类型时间、序号维度两两组合 时间维度 持久客户端与服务端断联服务端存储的客户端信息不会被删除 短暂客户端与服务端断联服务端存储的客户端信息会被删除 序号维度 有序号create节点名的时候带上-s 好处可以创建多个同名不同序的节点 无序号默认无序号 永久节点创建
节点值获取
永久有序节点创建
节点名不能重复创建重复会报错
临时节点客户端端口后服务端就会临时该断开客户端创建的节点删除
修改节点的值
