Node.js - cluster.fork() - 如何检查工人中工人的数量？

Question

当使用 cluster.fork 时，有没有办法检查 worker 创建的哪个数字在 worker 本身中？

if(cluster.isMaster) {
    console.log(`Master ${process.pid} is running`);    
    // Fork workers
    for (let i = 0; i < cores.length; i++) {
        cluster.fork();
    }
    cluster.on('exit', (worker, code, signal) => {
        console.log(`worker ${worker.process.pid} died`);
    });
}
else{   
    var number = CLUSTER_NUM; //Get the spawned number of the worker
}

Answer 1

cluster.worker.id应该是递增的数字。

if (cluster.isWorker) {
  console.log(cluster.worker.id); // 0, 1, 2 etc.
}
