Source: NodeJS Server to Linux Service Daemon 製作教學
Linux 系統中的服務，通常都是以 Daemon 的形式存在，Daemon 泛指一種在背景執行的程序，通常可以長時間工作不會中斷。最近剛好要將一個 Node.JS 所設計的系統執行在 Linux 中，由於 Linux 在慣例上會把服務封裝為 Linux Service 並且將啟動器集中在 /etc/init.d 目錄中進行管理。能夠遵循 Linux 的慣例佈署系統是個好方法，免得換了一個人維護就得換顆腦袋。

The problem of web server optimisation has been studied because a number of factors must be considered to allow a web server to support many clients. This can involve a combination of operating system constraints and web server software limitations.
