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

问题描述

我有一个简单的TCP服务器侦听端口。

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

var net = require("net");

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

server.listen(7777);

我以节点server.js 然后在Mac上使用Ctrl + Z关闭它。当我尝试使用节点server.js 再次运行它时，我收到此错误消息：

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)

b $ b

我是以错误的方式关闭程序吗？

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

推荐答案

要结束程序，应该使用 Ctrl + C SIGINT ，这允许程序正常结束，从任何正在侦听的端口解除绑定。

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.
