事件:'exit'

\Event: 'exit'

• worker <cluster.Worker>

• code <number> 如果其正常退出,则为退出码。

  \code <number> The exit code, if it exited normally.

• signal <string> 造成进程被终止的信号的名称(例如 'SIGHUP')。

  \signal <string> The name of the signal (e.g. 'SIGHUP') that caused the process to be killed.

当任何工作进程死亡时,则集群模块将触发 'exit' 事件。

\When any of the workers die the cluster module will emit the 'exit' event.

这可用于通过再次调用 .fork() 来重新启动工作进程。

\This can be used to restart the worker by calling .fork() again.

cluster.on('exit', (worker, code, signal) => {
 console.log('worker %d died (%s). restarting...',
 worker.process.pid, signal || code);
 cluster.fork();
}); 拷贝
