在亚马逊网络服务上运行harp.js

Question

我在基于node.js的亚马逊网络服务上设置了一个Elastic Beanstalk实例，并试图让它运行harp.js。

它在Heroku上用这个Procfile运行得很好：web: harp server --port $PORT

但在亚马逊网络服务上，没有Procfile (据我所知)，所以我将根目录中的package.json文件更改为：

   {
     "name": "Marketing-Website",
     "version": "1.0.0",
     "description": "My App",
     "dependencies": {
       "harp": "*"
     },
     "scripts": {
      "start": "harp server --port 80"
    }
   }

这似乎不起作用。在服务器日志中，我最终得到：

当我在没有--port 80的情况下运行它时，网站建立了，但我在根网站上得到了502错误网关错误。我转到了我认为是默认端口的地方，它在我身上超时了。

Answer 1

您需要以root访问权限运行它才能使用端口80

您可以将启动脚本更改为：

"scripts": {
  "start": "sudo harp server --port 80"
}
