Question

任何人都知道如何在Windows上运行Node Cluster？我还没能在网上找到任何文章，似乎无法解决这个问题：

events.js:160
      throw er; // Unhandled 'error' event
      ^

Error: write ENOTSUP
    at exports._errnoException (util.js:1007:11)
    at ChildProcess.target._send (internal/child_process.js:634:20)
    at ChildProcess.target.send (internal/child_process.js:521:19)
    at sendHelper (cluster.js:751:15)
    at send (cluster.js:534:12)
    at cluster.js:509:7
    at SharedHandle.add (cluster.js:99:3)
    at queryServer (cluster.js:501:12)
    at Worker.onmessage (cluster.js:449:7)
    at ChildProcess.<anonymous> (cluster.js:765:8)

代码......

if (cluster.isMaster) {
    for (let i = 0; i < numCPUs; i++) {
        cluster.fork();
    }
    cluster.on('online', (worker) => {
        console.log('Worker ' + worker.process.pid + ' is online');
    });
    cluster.on('exit', (worker, code, signal) => {
        console.log(`Worker ${worker.process.pid} died with code ${code} and signal ${signal}`);
    });
} else {
    console.log('else part ');
    openPort();
}

function openPort() {
    let server = dgram.createSocket('udp4');
    server.bind(port, host);
    server.on('message', processMessage);
}

Answer 1

v0.11.14（适用于Linux和OSX）中添加了对UDP群集的支持。检查node.js master上的file，其中说明＆＃34;目前Windows不支持dgram集群＆＃34;

Answer 2

在当前节点的js版本中，我使用下面的代码在Windows上创建集群。

<div style="width:100%;" id="comboDiv">   
     <div style="width: 100px; display: inline-block">
      <select style="width: 100%;"></select>
     </div>
     <div style="width: 200px; display: inline-block">
            <select style="width: 100%;"></select>
     </div>
     <input type="text" style="width: 10%; float:right;" />
 </div>

这将在同一端口上创建集群。

因此，为了在Windows上使用带有Node群集的UDP，你必须像这样调用server.bind：

server.bind({port: 1900, exclusive: true}, function () {
        console.log('PORT BIND SUCCESS');
        server.setBroadcast(true);
        server.setMulticastTTL(128);
        server.addMembership(multicastAddress, myIp);
    });

关键部分是将对象{port：PORT，exclusive：true}传递给bind函数。我在这里找到了答案：https://github.com/misterdjules/node/commit/1a87a95d3d7ccc67fd74145c6f6714186e56f571
