?forever讓nodejs應用后臺執行

命令如下：

forever start './bin/www'

?

nodejs一般是當成一條用戶命令執行的，當用戶斷開客戶連接，運用也就停了，很煩人。如何讓nodejs應用當成服務，在后臺執行呢？

最簡單的辦法(不推薦)：

$ nohup node app.js &

?

但是，forever能做更多的事情，比如分別記錄輸出和錯誤日志，比如可以在js中作為api使用。

forever安裝：

$ sudo npm install forever -g #安裝 $ forever start app.js #啟動 $ forever stop app.js #關閉 $ forever start -l forever.log -o out.log -e err.log app.js #輸出日志和錯誤

?

This is extremely useful for remote starting simple node.js scriptswithout using nohup. It is recommended to run start with -o -l, & -e.ex. forever start -l forever.log -o out.log -e err.log my-daemon.jsforever stop my-daemon.js

由于express4.x后，目錄結構變化，運行方式改變，在此備注。
