在Amazon Ubuntu EC2 Web服務器上運行的SailsJS App

Question

我剛開始在EC2上托管我的SailsJS應用程序，我為此付出了很多努力。 我無法使該應用程序在端口80上運行。所以我所做的是將默認的Apache監聽端口80更改為8080。

但是仍然無法取消Sails，但出現此錯誤。

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`)

就像我嘗試過Sudo一樣，但是隨后該應用程序啟動了。 涼。

然后我在終端上得到所有這些錯誤

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

而我的瀏覽器控制台上的此錯誤

WebSocket連接到'ws：//mywebsite.co/socket.io/1/websocket/GXGSRKCiYhST-7CMcXkm？__sails_io_sdk_version = 0.10.0＆__ sails_io_sdk_platform = browser＆__ sails_io_sdk_language = javascript'失敗

這是ubuntu> netstat，如果有幫助，為什么要理解

該應用似乎存在未關閉的連接

您可能會在這里看到。 因此該應用永遠不會因為網絡套接字而關閉

如果您一生中都這樣做，請提供幫助。 我很高興刪除所有配置並從頭開始。

從您提到“默認Apache端口”的事實來看，我猜您是從不一定對Node應用程序最佳的AMI開始的。 我建議從EC2上的Bitnami Node.js AMI開始。 使用該AMI在EC2實例上設置Sails應用程序沒有任何問題。 它可能沒有預裝MySQL，但這就是apt-get目的，對吧？
