Google Compute Engine Bookshelf教程：npm ERR！网络阅读ECONNRESET

Question

我目前通过GCE书架教程，这是给我最头痛的工作：https://cloud.google.com/nodejs/tutorials/bookshelf-on-compute-engine

我卡在这一步：

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

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

当我尝试查看我的应用程序通过端口8080我的外部IP，没有任何反应。

我可以证实，防火墙规则正确与我的虚拟机实例显示正确的网络标签应用。

我通过串行日志去了，这才意识到出事了，在该实例无法克隆Git仓库的启动脚本。

因此，我改变

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在这里:)

即使我的VM实例现在正确地克隆git回购，它现在收到ECONNRESET错误：

说实话，我不知道这是否有助于我为什么不能查看外部IP我的应用程序的原因，但在目前，这是我唯一能发现错误。我如何解决这个问题？

Answer 1

有一两件事要检查出是哪些端口是你防火墙规则开放。针对HTTP的默认端口为80，HTTPS为443

转至防火墙规则，看看你允许访问您的外部IP地址的端口。为了获得在汉堡有第一次点击您的GCP控制台的左上角，则：

网络 - >防火墙规则

现在，看看你有开放的HTTP访问端口。您可以调整服务器以侦听端口80或添加防火墙规则以侦听tcp：80。确保您的虚拟机已添加到创建新规则的网络中（因此请确保将该规则添加到默认网络）。

我会说实话，开发-OPS教程，不要做大量的手把手的，而且往往留下了很多的步骤。
