Node.js 在Amazon Ubuntu EC2 web服务器上运行的SailsJS应用程序

我刚开始在EC2上运行我的SailsJS应用程序，我为此奋斗了很多。我无法使应用程序在端口80上运行。因此，我所做的是将默认的apache侦听端口80更改为8080

但仍然无法扬帆，我得到了这个错误

warn: error raised: Error: listen EACCES

error: Server doesn't seem to be starting.
error: 
error: Troubleshooting tips:
error: 
error:  -> Do you have permission to use port 80 on this system? (you might try `sudo`)
error: 
error:  -> Is something else already running on port 80 ?
error: 
error:  -> Are you deploying on a platform that requires an explicit hostname, like OpenShift?
error:     (Try setting the `explicitHost` config to the hostname where the server will be accessible.)
error:     (e.g. `mydomain.com` or `183.24.244.42`)

正如上面说的，我试过Sudo，但后来应用程序启动了。酷

然后我在终端上得到所有这些错误

warn: websocket connection invalid
warn: websocket connection invalid
warn: websocket connection invalid
warn: websocket connection invalid

这是我的浏览器控制台上的错误

连接到“ws://mywebsite.co/socket.io/1/WebSocket/GXGSRKCiYhST-7CMcXkm？”的WebSocket失败：在收到握手响应之前连接已关闭

这是ubuntu>netstat，如果这有助于理解为什么

应用程序中似乎存在未关闭的连接

正如你在这里看到的。因此，该应用程序从未因为web套接字而关闭

如果你在生活中这样做过，请帮助我。我很高兴删除所有配置，从头开始。

从您提到的“默认Apache端口”的事实来看，我猜您是从一个AMI开始的，它不一定是节点应用程序的最佳配置。我建议从EC2上的开始。在使用该AMI的EC2实例上设置Sails应用程序时，我没有遇到任何问题。它可能不是随MySQL预装的，但这正是apt-get的用途，对吗？

您找到解决方案了吗？
