Question

我的node.js集群能够启动2个工作进程并且工作正常。这是伪代码。但是，如果我打开Windows任务管理器来杀死node.js进程，我预计它会重新启动。但它引发了错误（错误：频道关闭）。

if (cluster.isMaster) {

  for (var i = 0; i < numCPUs; i++) {
    cluster.fork();
  }

  cluster.on('death', function(worker) {
    logger.fatal('worker ' + worker.pid + ' died. Restarting again ...');

    cluster.fork();


  });

} else {
  // Worker processes have a express server.
  .........
  .........
}

错误：

看起来socket.io-clusterhub有问题。这是某种配置错误还是错误？

Answer 1

该问题已在最新的clusterhub版本0.1.2中得到解决 socket.io-clusterhub在内部使用clusterhub，所以如果你更新socket.io-clusterhub，它应该可以工作。
