如何解决在DigitalOcean上使用NGINX的ExpressJS上的路由错误和域名问题 问题1 问题2 Nginx.conf default.conf Express路由器 Express主要

在这一点上，我绝对要拔头发，以找出我做错了什么。我在第7天无法使用Express和Nginx正常工作。尝试使用我拥有的所有资源，转到我可以找到的每个教程，并遍历stackOverflow数百次，我仍然感觉自己陷入了死胡同，对错误之处感到困惑。

我所能到达的最远的地方是只能访问地址为http://<ip address>的快递服务的单个页面。

---

问题1

有效的方法：只有http://< ip address >中的router.get('/')。

无效的内容：www.myDomain.app或myDomain.app都无法连接到我所服务的网页。
什么也不起作用： https://< ip address >（https / ssl）

---

问题2

我所服务的第一页（在http://< ip address>上有效。）当我尝试路由到/page1或/page2时，出现not found错误。这似乎是express产生的错误。

错误消息：

Not Found
  404
