我在我的服務器上安裝了一個名爲node.js的程序,用於監聽端口8088如何爲程序設置init.d腳本?

我的服務器是來自hostgator的VPS包級別3。

現在我試圖創建一個init.d腳本,以便node.js可以自動運行系統,並且可以在發生崩潰時自動重啓。

經過一番搜索之後,我發現了一些資源,並且找到了一個init.d腳本。它更像是一個複製粘貼工作,你可以看到:)我得到了一些問題,其中最有可能包括具有錯誤的sysntax的init.d腳本。

rc_exit 

我真的很困惑,因爲不同的系統使用不同的方法。我的本地ubuntu使用了一些叫做upstart的東西,但我的服務器似乎沒有暴發戶,只使用init.d腳本。

如果我發出了一個「UNAME -A」我得到這個:

Linux onl.onlyfreelancer.com 2.6.18-028stab070.14 #1 SMP 
Thu Nov 18 16:04:02 MSK 2010 x86_64 x86_64 x86_64 GNU/Linux 

而且,我似乎無法找到像「insserv時」 utils的啓用此的init.d腳本。所以,如果我的init.s腳本是正確的,我怎麼才能正確設置它?

任何幫助,非常感謝,我一直在爭取這個事情2天沒有運氣了。

'less'命令在我的ubuntu 10.10上不起作用: - 沒有這樣的目錄作爲'/ usr/share/doc/initscripts - * /' – pavium 2011-04-28 11:43:31

啊是的,但OP還提到了Ubuntu - 完全不同。我很困惑。 – pavium 2011-04-28 11:47:00

對於關鍵應用程序,您可能還會考慮「不啓動服務,運行它們」方法。 supervisorddaemontools可能對此有所幫助。
