简单五步设置群晖NAS绑定阿里云自有域名实现外网访问

1.注册阿里云账号。
2.注册一个域名。
如果域名不在阿里云解析托管，需要先转过去，具体方法是联系域名提供商修改域名的DNS服务器，修改方式参考这里：https://help.aliyun.com/knowledge_detail/39844.html
然后去控制台找到云解析，将域名添加进去；
3.到阿里云控制中心找到access key和secret并保存下来（强烈建议遵循阿里云安全最佳实践的说明，使用RAM子用户的AccessKey）；
4.到群晖控制中心找到任务计划新增一个计划。
新增->计划的任务->用户自定义脚本
设置10分钟定时
复制附件中内容（附件：阿里云动态域名更新脚本.txt ），根据自己的情况修改中文部分并添加到任务设置自定义脚本
