无法从公共ip访问AWS Linux(Ubuntu)托管的应用程序 [英] AWS Linux (Ubuntu) hosted application is not accessible from public ip

问题描述

我在免费层的AWS Linux(Ubuntu 16.04)上托管了一个nodejs(express hello world app)应用程序.当我执行wget http://localhost:8080时，它将成功运行并将输出保存在index.html文件中. 但是，当我使用实例的公共IP(wget http://35.154.40.189:8080)做同样的事情时，它会说

I hosted a nodejs(express hello world app) application on AWS Linux(Ubuntu 16.04) on free-tier. When i do wget http://localhost:8080 it runs successfully and saved the output in index.html file. But when i do the same thing with the public ip (wget http://35.154.40.189:8080) of my instance, it says

Connecting to 35.154.40.189:8080... failed: No route to host.

我还使用了 http://www.lauradhamilton.com/how-to-set-up-a-nodejs-web-server-on-amazon-ec2 将所有ipv4流量转发到我的应用程序，但它没有不行.

I also used the steps given in http://www.lauradhamilton.com/how-to-set-up-a-nodejs-web-server-on-amazon-ec2 to forward all ipv4 traffic to my application but it doesn't work.

我还从aws控制台启用了端口8080.

I also enabled port 8080 from aws console.

netstat -atn says 

netstate -ntlp says

我尝试了所有可以从互联网上获取的内容，但无法解决该问题.现在我实在太沮丧了.任何帮助都是非常可取的.

I tried everything which i get on internet but unable to resolve the issue. Now i'm too much frustrated. Any help would be highly appreciable.
