Google Compute Engine Bookshelf教程：npm ERR！網絡閱讀ECONNRESET

Question

我目前通過GCE書架教程，這是給我最頭痛的工作：https://cloud.google.com/nodejs/tutorials/bookshelf-on-compute-engine

我卡在這一步：

To see the application running, go to http://[YOUR_INSTANCE_IP]:8080, 

where [YOUR_INSTANCE_IP] is the external IP address of your instance. 

當我嘗試查看我的應用程序通過端口8080我的外部IP，沒有任何反應。

我可以證實，防火牆規則正確與我的虛擬機實例顯示正確的網絡標籤應用。

我通過串行日誌去了，這才意識到出事了，在該實例無法克隆Git倉庫的啓動腳本。

因此，我改變

git clone https://source.developers.google.com/p/$PROJECTID /opt/app

到

git clone https://source.developers.google.com/p/d3-barchart/r/repo /opt/app

（REST的startup-script.sh在這裏:)

說實話，我不知道這是否有助於我爲什麼不能查看外部IP我的應用程序的原因，但在目前，這是我唯一能發現錯誤。我如何解決這個問題？

Answer 1

有一兩件事要檢查出是哪些端口是你防火牆規則開放。針對HTTP的默認端口爲80，HTTPS爲443

轉至防火牆規則，看看你允許訪問您的外部IP地址的端口。爲了獲得在漢堡有第一次點擊您的GCP控制檯的左上角，則：

網絡 - >防火牆規則

現在，看看你有開放的HTTP訪問端口。您可以調整服務器以偵聽端口80或添加防火牆規則以偵聽tcp：80。確保您的虛擬機已添加到創建新規則的網絡中（因此請確保將該規則添加到默認網絡）。

我會說實話，開發-OPS教程，不要做大量的手把手的，而且往往留下了很多的步驟。
