Amazon Lightsail VPS不能与Nginx一起使用吗？ （Django React项目部署）

Question

我已经向Amazon VPS服务Amazon Lightsail新注册。正确设置我的Django应用，Gunicorn和Nginx之后，流量似乎有问题吗？

[我在Ubuntu 18上使用相同的过程在两个不同的VPS上设置了相同的Django应用程序，]

IP无法在AWS（13.124.94.92）上运行：

~# ping -c3 13.124.94.92
PING 13.124.94.92 (13.124.94.92) 56(84) bytes of data.

--- 13.124.94.92 ping statistics ---
3 packets transmitted, 0 received, 100% packet loss, time 2044ms
[IP在另一个VPS Ubuntu 18中运行正常（5.63.152.4）：

~# ping -c3 5.63.152.4
PING 5.63.152.4 (5.63.152.4) 56(84) bytes of data.
64 bytes from 5.63.152.4: icmp_seq=1 ttl=64 time=0.063 ms
64 bytes from 5.63.152.4: icmp_seq=2 ttl=64 time=0.108 ms
64 bytes from 5.63.152.4: icmp_seq=3 ttl=64 time=0.082 ms

--- 5.63.152.4 ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2043ms
rtt min/avg/max/mdev = 0.063/0.084/0.108/0.019 ms
第一个IP没有显示'Welcome to Nginx'页面，而第二个IP却显示（http://5.63.152.4/）

我不确定该从哪里开始调试...我对iptables有点弄弄，因为mosh无法正常工作。请帮忙！谢谢！！

对于其他像我这样的新手：

问题已解决... Amazon Lightsail在控制面板上的“网络”标签下有自己的防火墙。因此，无需在Ubuntu中自行设置ufw。 Nginx的欢迎页面根本不会显示。将您的域指向Lightsail实例的公共IP后，就一切就绪。
