NODJS Multi-thread master-slave mode

# #work. js

Let HTTP = require (' http ');

Let port  = Math.Round ((1+math.random ()) *1000);
Http.createserver (function (req, res) {
    Console.log (PROCESS.PID);
    Res.writehead (200,{' content-type ': ' Text/plain ');
    Res.end (' Hello World ');
}). Listen (Port,function () {
Console.log ('----Server start port: ' +port ');
});

# # Master.js

Let fork = require (' child_process '). Fork;

Let CPUs = require (' OS '). CPUs;
Console.log (cpus.length);
Replicate the number of node processes based on the number of CPUs on the current machine
for (let i=0;i<2;i++) {
    Fork ('./work.js ');
}

1, start the work.js first, and then start the master.js. You can see the boot work.js when listening to a port, and then start the master.js when the thread listens to the other two ports.
You can start a certain thread service by detecting the number of CPUs in the current system.
