节点/Express:EADDRINUSE，地址已在使用中

本文介绍了节点/Express:EADDRINUSE，地址已在使用中-终止服务器的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个使用connect在node.js中运行的简单服务器:

I have a simple server running in node.js using connect:

var server = require('connect').createServer(); //actions... server.listen(3000);

在我的代码中，我有实际的处理程序，但这就是基本思想.我一直遇到的问题是

In my code I have actual handlers, but thats the basic idea. The problem I keep getting is

EADDRINUSE, Address already in use

在先前崩溃或错误后再次运行我的应用程序时，我收到此错误.因为我没有打开终端的新实例，所以我用ctr + z关闭了该过程.

I receive this error when running my application again after it previously crashed or errors. Since I am not opening a new instance of terminal I close out the process with ctr + z.

我可以肯定，我要做的就是关闭服务器或连接.我试过在process.on('exit', ...);中打电话给server.close()并没有运气.

I am fairly certain all I have to do is close out the server or connection. I tried calling server.close() in process.on('exit', ...); with no luck.

推荐答案

首先，您想知道哪个进程正在使用port 3000

First, you would want to know which process is using port 3000

sudo lsof -i :3000

这将列出在此端口上侦听的所有 PID ，一旦您拥有 PID ，就可以使用以下命令终止该端口:

this will list all PID listening on this port, once you have the PID you can terminate it with the following:

kill -9 {PID}
