Google Compute Engine Bookshelf教程:npm ERR! networking读取ECONNRESET

我目前正在通过GCE Bookshelf教程,这是最让我头疼的: https : //cloud.google.com/nodejs/tutorials/bookshelf-on-compute-engine

我被困在这一步:

To see the application running, go to http://[YOUR_INSTANCE_IP]:8080, where [YOUR_INSTANCE_IP] is the external IP address of your instance. 

当我尝试通过端口8080在我的外部IP上查看我的应用程序时,没有任何反应。

我可以确认防火墙规则正确地应用于显示正确networking标记的虚拟机实例。

我浏览了系列日志,发现启动脚本有些问题,因为实例无法克隆git仓库。

所以我改变了

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

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

(其余的startup-script.sh这里:)

即使我的虚拟机实例现在正确地克隆git仓库,它现在收到一个ECONNRESET错误:

说实话,我不知道这是为什么我不能在外部IP上查看我的应用程序的原因,但目前,这是我唯一能find错误的地方。 我该如何解决这个问题?

有一点要注意的是哪些端口在防火墙规则中是打开的。 HTTP的默认端口是80,https是443。

去防火墙规则,看看你允许访问你的外部IP地址的端口。 首先点击你的GCP控制台左上angular的汉堡包,然后:

networking – >防火墙规则

现在,看看你打开HTTP端口。 您可以调整您的服务器以侦听端口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build新规则的networking中(因此请确保将规则添加到默认networking)。

老实说,Dev-Ops的教程并没有做太多的手工操作,而且往往省去了很多步骤。
