Question

我在端口5000上的基于Centos 7的VM中运行节点应用程序。当我在VM中打开浏览器时，我可以访问http://localhost:5000。我也在Virtualbox中转发端口5000 / TCP。直到最近，我才能在我的主机上访问相同的URL。我可以通过SSH进入机器，所以我可以认为客人的加入不应该受到责备。

当我从主机卷曲时，我得到以下输出：

curl -v http://localhost:5000
* Rebuilt URL to: http://localhost:5000/
*   Trying ::1...
*   Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 5000 (#0)
> GET / HTTP/1.1
> Host: localhost:5000
> User-Agent: curl/7.46.0
> Accept: */*
>
* Recv failure: Connection was reset
* Closing connection 0
curl: (56) Recv failure: Connection was reset

来宾的卷曲成功：

curl -v localhost:5000
* About to connect() to localhost port 5000 (#0)
*   Trying ::1...
* Connected to localhost (::1) port 5000 (#0)
> GET / HTTP/1.1
> User-Agent: curl/7.29.0
> Host: localhost:5000
> Accept: */*
>

端口转发设置如下所示 - 只有SSH工作，虽然我已经尝试添加和删除主机IP到我想要访问的服务。

如何进一步排查？

这可能是最新版Virtualbox的问题吗？

在VM机中停止防火墙守护程序对我来说是可行的。谢谢@哈里·金

sudo systemctl停止firewalld

禁用前的卷曲结果：

* Recv failure: Connection was reset
* Closing connection 0
curl: (56) Recv failure: Connection was reset

禁用后：

< HTTP/1.1 404
< Content-Type: application/json;charset=UTF-8
< Transfer-Encoding: chunked

{"timestamp":1604040463217,"status":404,"error":"Not Found","message":"No message available","path":"/"}* Connection #0 to host 127.0.0.1 left intact

端口转发不适用于Virtualbox 5.1.2中的Web服务
