worker.exitedAfterDisconnect

• <boolean>

如果工作进程由于 .kill() 或 .disconnect() 退出，则此属性为 true。 如果工作进程以任何其他方式退出，则为 false。 如果工作进程没有退出，则为 undefined。

布尔值 worker.exitedAfterDisconnect 可以区分自愿退出和意外退出，主进程可以根据此值选择不重新衍生工作进程。

cluster.on('exit', (worker, code, signal) => {
  if (worker.exitedAfterDisconnect === true) {
    console.log('Oh, it was just voluntary – no need to worry');
  }
});

// 杀死工作进程
worker.kill();

• <boolean>

This property is true if the worker exited due to .kill() or .disconnect(). If the worker exited any other way, it is false. If the worker has not exited, it is undefined.

The boolean worker.exitedAfterDisconnect allows distinguishing between voluntary and accidental exit, the master may choose not to respawn a worker based on this value.

cluster.on('exit', (worker, code, signal) => {
  if (worker.exitedAfterDisconnect === true) {
    console.log('Oh, it was just voluntary – no need to worry');
  }
});

// kill worker
worker.kill();
