错误：侦听EACCES 0.0.0.0:80 OSx Node.js [英] Error: listen EACCES 0.0.0.0:80 OSx Node.js

问题描述

我正在关注angularJS书中的教程并且必须设置服务器。这是server.js文件：

I'm following a tutorial in a angularJS book and have to setup a server. This is the server.js file:

 var express = require('express');
  var app = express();
   app.use('/', express.static('./'));
    app.listen(80);

我收到此错误：

$ node server.js
events.js:154
      throw er; // Unhandled 'error' event
      ^

Error: listen EACCES 0.0.0.0:80

我已经知道，错误EACCES意味着我没有端口80的访问权限，但我不知道如何解决这个问题。
任何帮助非常感谢！

I know already, that the Error EACCES means that i don't have access rights to the port 80, but i don't know how to fix this. Any help much appreciated!

推荐答案

如果你需要在端口80上运行服务器，你应该使用反向代理，如 nginx 将使用特权端口上的系统帐户运行，并将请求代理到在非特权端口（> 1024）上运行的Node.js服务器。

If you need to run the server on port 80 you should use a reverse proxy like nginx that will run using a system account on a privileged port and proxy the requests to your Node.js server running on an unprivileged port (> 1024).

在开发环境中运行时，您可以自由地以root身份运行（即。 sudo node server.js ），但这在生产环境中相当危险。

When running in development environment you're pretty much free to run as root (ie. sudo node server.js), but that is rather dangerous in production environment.

这是一个示例nginx配置，它将查看请求是否适用于文件系统中存在的文件，以及不，将请求代理到在端口9000上运行的Node.js服务器

Here's a sample nginx config that will see if the request is for a file that exists in the filesystem, and if not, proxy the request to your Node.js server running on port 9000

upstream yournodeapp {
  server localhost:9000 fail_timeout=0;
  keepalive 60;
}

server {
  server_name localhost;
  listen 80 default_server;

  # Serve static assets from this folder
  root /home/user/project/public;

  location / {
    try_files $uri @yournodeapp;
  }

  location @yournodeapp {
    proxy_pass http://yournodeapp;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
  }
}
