在Linux上守护Java应用程序的最佳方法 [英] Best way to daemonize Java application on Linux

问题描述

虽然我多次在SW上发现这个问题的答案，但我没有找到最后的答案。

我不是在寻找使用任何外部包装器，因为我发现它们在低于自身的低级别下启动java进程，这可能会降低性能，所以似乎只剩下shell方法。

<到目前为止，我发现了3种不同的shell方法：

• start-stop-daemon


• RedHat守护进程init.d功能


• 启动后启动/拒绝nohup

你的人是什么使用，并建议作为最可靠的方法？

谢谢。

解决方案

虽然标准答案似乎是 jsvc ，但我一直在使用djb的守护进程工具成为一个守护进程的好方法。

我有java，python和一些shell脚本都作为守护进程运行，有一个简单的启动/停止方式他们和伟大的日志记录。

我曾经在初始设计的initctl上以root身份运行daemontools本身，但几个月后我决定手动运行它，在一个普通用户，并使用 svscan-start 进行更好的日志记录。

While I found this question being answered here on SW several times, I didn't find a concluding answer what is the best approach.

I'm not looking to use any external wrapper, as I found them launching the java process under a nice level lower then themselves which potentially lowers the performance, so it seems only the shell methods are left.

I so far found 3 different shell methods:

• start-stop-daemon
• RedHat daemon init.d function
• nohup on start / disown after start

What you people are using, and can recommend as the most reliable method?

Thanks.

解决方案

While the standard answer to this seems to be jsvc, I have been using djb's daemon tools to be a great way to make anything into a daemon.

I have java, python and a few shell scripts all running as daemons, with a simple way to start/stop them and great logging.

I've used to run daemontools itself as root on initctl as originally designed, but after a few months I decided to run it manually, under a normal user, and using svscan-start for nicer logging.
