Node.js + express.js-PM2和永遠無法正常工作?

[英]Nodejs + expressjs - pm2 and forever don't work?

我想讓一個應用程序在我的nodejs服務器上永遠運行。 但是它似乎不適用於pm2永遠

如果我手動啟動該應用程序:

$ npm start

> iot@1.0.0 start /var/www/path/to/myapp
> node ./bin/www

我可以在瀏覽器中成功看到該應用程序。

但是對於PM2

$ pm2 start /var/www/path/to/myapp/app.js

[PM2] Applying action restartProcessId on app [app](ids: 0)
[PM2] [app](0) ✓
[PM2] Process successfully started
┌──────────┬────┬──────┬───────┬────────┬─────────┬────────┬─────────────┬──────────┐
│ App name │ id │ mode │ pid   │ status │ restart │ uptime │ memory      │ watching │
├──────────┼────┼──────┼───────┼────────┼─────────┼────────┼─────────────┼──────────┤

└──────────┴────┴──────┴───────┴────────┴─────────┴────────┴─────────────┴──────────┘

我也嘗試過這個:

$ cd /var/www/path/to/myapp
$ pm2 start app.js

它說該應用程序在線。 但是,當我嘗試在瀏覽器上訪問該應用程序時: http : //127.0.0.1 : 3000/

我收到此錯誤:

此網頁無法使用

ERR_CONNECTION_REFUSED

與永遠:

$ sudo forever start app.js
warn:    --minUptime not set. Defaulting to: 1000ms
warn:    --spinSleepTime not set. Your script will exit if it does not stay up for at least 1000ms
info:    Forever processing file: app.js

但是根本沒有運氣。

有什么想法我錯過了嗎?

編輯:

在package.json中:

{
  "name": "iot",
  "version": "1.0.0",
  "private": true,
  "scripts": {
    "start": "node ./bin/www"
  },
  "dependencies": {
    "bcrypt": "^0.8.7",
    "body-parser": "~1.15.1",
    "connect-mongo": "^1.2.1",
    "cookie-parser": "~1.4.3",
    "debug": "~2.2.0",
    "express": "~4.14.0",
    "express-session": "^1.13.0",
    "hat": "0.0.3",
    "rand-token": "^0.2.1",
    "method-override": "^2.3.6",
    "mongoose": "^4.5.1",
    "morgan": "~1.7.0",
    "pug": "~2.0.0-beta3",
    "serve-favicon": "~2.3.0"
  }
}

如果我刪除"scripts"並運行npm update

{
  "name": "iot",
  "version": "1.0.0",
  "private": true,
  "dependencies": {
    "bcrypt": "^0.8.7",
    "body-parser": "~1.15.1",
    "connect-mongo": "^1.2.1",
    "cookie-parser": "~1.4.3",
    "debug": "~2.2.0",
    "express": "~4.14.0",
    "express-session": "^1.13.0",
    "hat": "0.0.3",
    "rand-token": "^0.2.1",
    "method-override": "^2.3.6",
    "mongoose": "^4.5.1",
    "morgan": "~1.7.0",
    "pug": "~2.0.0-beta3",
    "serve-favicon": "~2.3.0"
  }
}

然后,我再次手動啟動應用程序,但出現錯誤:

$ npm start
npm ERR! Linux 3.13.0-76-generic
npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "start"
npm ERR! node v5.10.1
npm ERR! npm  v3.8.3

npm ERR! missing script: start
npm ERR! 
npm ERR! If you need help, you may report this error at:
npm ERR!     <https://github.com/npm/npm/issues>

問題是由express-generator引起的,我用它來生成我的應用程序項目!

它有一個運行http的bin文件夾。 所以我必須先cd bin然后pm2 start www
