Question

我正在尝试按照提到的https://github.com/joyent/node/issues/2194

运行以下节点js应用程序

var util = require("util"),
  dgram = require("dgram"),
  cluster = require('cluster');

var udp = dgram.createSocket("udp4");
var port = 1190;

if (cluster.isMaster) {
  for (i = 0; i < 2; i++) {
    cluster.fork();
  }
} else {
  util.log("starting udp server on port " + port);
  udp.on("error", function (error) {
    util.log("failed to bind to UDP port - " + error)
  });
  udp.bind(port);
}

应用程序会立即退出并输出以下内容：

23 May 23:22:13 - starting udp server on port 1190
23 May 23:22:13 - starting udp server on port 1190

events.js:72
        throw er; // Unhandled 'error' event
              ^

有谁知道发生了什么事？没有集群运行时，一切都很好。看来群集不支持udp？

一些规格：

Window 7 x64
node js 0.10.7

Answer 1

它表示在v0.11.14中添加了对UDP群集的支持所提供的链接。您可能只需要更新node.js的版本

节点js 0.10.7：集群支持udp dgram？
