我在服务器上安装了一个名为node.js的程序来侦听端口8088
我的服务器是来自hostgator的VPS包3级。
现在我正在尝试创建一个init.d脚本,以便node.js可以自动运行系统,并且可以在自动崩溃时重新启动。
在谷歌搜索之后,我遇到了一些资源并混淆了一个init.d脚本。它更像是一个复制粘贴工作,你可以看到:)我遇到了一些问题,其中很可能包括init.d脚本有错误的sysntax。

我真的很困惑,因为不同的系统使用不同的方法。我的本地ubuntu使用了一个名为upstart的东西,但我的服务器似乎没有upstart,只使用init.d脚本。
如果我发出“uname -a”,我会得到这个:
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
此外,我似乎无法找到像“insserv”这样的工具来启用此init.d脚本。所以,如果我的init.s脚本是正确的,我该如何正确设置它?
任何帮助都非常感激,我已经和这个东西争斗了2天没有运气了。

对于关键应用,您可能还会考虑“不启动服务,运行它们”的方法。 supervisord和daemontools可能对此有所帮助。
