我在 worker.js 里 console.log('ooxx')，在浏览器刷新页面会出现2~5条的ooxx，什么情况？

我用的是Express，worker.js里有连接MongoDB的代码，这样是不是多次连接数据库了？

[aleafs]

代码弄上来给我看看

[antife-yinyue]

就你wiki上的代码

[antife-yinyue]

就在http.emit('connection', socket)下一行写了console

[antife-yinyue]

具体代码得4号上班才能贴上来了

另，如果一服务器有多个独立app，master.js要写几份？独立于各项目之外，还是跟项目走？

[aleafs]

肯定是随项目走了

[aleafs]

你console.log的意思是每个HTTP请求进来都打印一个ooxx

[antife-yinyue]

master.js:

var master = require('pm').createMaster({
  pidfile: __dirname + '/tmp/jenny.pid'
})

master.register('http', __dirname + '/app.js', {
  listen: 3000
})

master.on('giveup', function(name, num, pause) {
  console.log('Master giveup to restart "%s" process after %d times. pm will try after %d ms.', name, fatals, pause)
})

master.dispatch()

app.js:

var express = require('express')
var mongoskin = require('mongoskin')
var app = express()

app.configure(function() {
  var db = mongoskin.db('xxxx', { safe: true })
  app.use(function(req, res, next) {
    req.db = db
    next()
  })
})

var http = require('http').createServer(app)
require('pm').createWorker().ready(function(socket, port) {
  http.emit('connection', socket)
  console.log(
    'Express server listening on port %d within %s environment.',
    port, app.get('env')
  )
})

$ node master.js

然后在浏览器访问localhost:3000

[aleafs]

这个没错的，每个request打印一个console.log。
看你的意思应该是需要监听worker的listen事件，https://github.com/aleafs/pm/wiki/Worker

[antife-yinyue]

app.js 调整下:

var express = require('express')
var mongoskin = require('mongoskin')
var app = express()

app.configure(function() {
  var db = mongoskin.db('xxxx', { safe: true })

  console.log('MongoDB connected')

  app.use(function(req, res, next) {
    req.db = db
    next()
  })
})

var http = require('http').createServer(app)
require('pm').createWorker().ready(function(socket, port) {
  http.emit('connection', socket)
})

console.log(
  'Express server listening on port %d within %s environment.',
  3000, app.get('env')
)

$ node master.js

app.js被调用了 8 次？MongoDB也连了 8 次？

[aleafs]

你是8核CPU么？默认按CPU数起进程的

[antife-yinyue]

4核的啊
