在Node.js中侦听EADDRNOTAVAIL错误 [英] listen EADDRNOTAVAIL error in Node.js

问题描述

我在服务器中安装了Nginx和Node.js.

I installed Nginx and Node.js in my server.

当我尝试运行我的node.js文件时，出现错误：

When I try run my node.js file, I get an error:

node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^
Error: listen EADDRNOTAVAIL
    at errnoException (net.js:614:11)
    at Array.0 (net.js:689:28)
    at EventEmitter._tickCallback (node.js:192:40)

如何我可以解决这个问题吗？

How can I fix this problem?

谢谢！

推荐答案

我有这个问题，我认为这是一个端口问题，但结果却是 IP 问题。

I had this issue, and I thought it was a port issue, but it turned out to be an IP issue.

我的 HOST 环境变量指向静态IP，我的节点服务器正在侦听该地址。在我的路由器回收的某个时刻，它开始为我的机器分配一个新IP，我开始收到你发布的错误。它是通过更改我的服务器正在收听的地址来修复的。

I had my HOST environmental variable pointing to a static IP, and my Node server was listening to that address. At some point when my router recycled, it started assigning my machine a new IP, and I started getting the error you posted. It was fixed by changing the address my server was listening to.

我的配置：

app.set('port', process.env.PORT || 3000);
app.set('host', process.env.HOST || '0.0.0.0');

http.createServer(app).listen(app.get('port'), app.get('host'), function(){
  console.log("Express server listening on port " + app.get('port'));
});

确保您的主机正在点击您的计算机。在任何情况下，@ miltonb建议的环回应始终有效：

Make sure your host is hitting your machine. In any case, the loopback, as @miltonb suggested, should always work:

app.set('host', '127.0.0.1');
