从命令行停止 node.js 程序 [英] Stop node.js program from command line

问题描述

我有一个侦听端口的简单 TCP 服务器.

I have a simple TCP server that listens on a port.

var net = require("net");

var server = net.createServer(function(socket) {
    socket.end("Hello!
");
});

server.listen(7777);

我用 node server.js 启动它，然后在 Mac 上用 Ctrl + Z 关闭它.当我尝试使用 node server.js 再次运行它时，我收到以下错误消息:

I start it with node server.js and then close it with Ctrl + Z on Mac. When I try to run it again with node server.js I get this error message:

node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
          ^
Error: listen EADDRINUSE
at errnoException (net.js:670:11)
at Array.0 (net.js:771:26)
at EventEmitter._tickCallback (node.js:192:41)

我是否以错误的方式关闭程序?我怎样才能防止这种情况发生?

Am I closing the program the wrong way? How can I prevent this from happening?

推荐答案

要结束程序，你应该使用 Ctrl + C.如果你这样做了，它会发送 SIGINT，它允许程序优雅地结束，从它正在侦听的任何端口中解除绑定.

To end the program, you should be using Ctrl + C. If you do that, it sends SIGINT, which allows the program to end gracefully, unbinding from any ports it is listening on.
