[英]How to publicly view website that I am hosting on amazon-ec2?
我已經啟動了一個Amazon-ec2實例,並公開了ec2-12-34-567-89.us-west-2.compute.amazonaws.com的DNS。 我在那里設置了一個安全組,其中類型為HTTP,協議為TCP,端口范圍為80,源為0.0.0.0/。 我登錄到EC2實例並啟動我的應用程序:
$ python3 run.py
* Running on http://0.0.0.0:0/
然后,使用瀏覽器嘗試打開: http : //ec2-12-34-567-89.us-west-2.compute.amazonaws.com並收到“無法連接”消息。
我在這里想念什么?

使用端口80,它最終會像這樣:
$ python3 run.py
* Running on http://0.0.0.0:80/
Traceback (most recent call last):

顯然我需要以超級用戶身份運行代碼。
$ **sudo** python3 run.py
* Running on http://0.0.0.0:80/
