一個(gè)cluster集群小demo
// 引入程序
const app = require('./app')
const cluster = require('cluster')
if (cluster.isMaster) {
let total = require('os').cpus().length - 1
console.log('running %d total workers', total)
for (let i = 0; i < total; i++) {
cluster.fork()
}
cluster.on('exit', (worker) => {
console.log('worker %d died', worker.id)
cluster.fork()
})
} else {
console.log('worker pid: ', process.pid)
app.listen('9898')
}
