如何将现有Java应用程序转换为SYS V服务（守护程序） [英] How to convert an existing Java application to a SYS V service (daemon)

问题描述

我有一个Java应用程序，启动它我使用

I have a Java application, to start it I use

java -jar myapp.jar

java -jar myapp.jar

要停止它我使用CTRL + C.

To stop it I use CTRL+C.

现在我需要将该应用程序转换为我可以从以下开始：

Now I need to convert that application to something that I can start with:

/etc/init.d/myapp start

/etc/init.d/myapp start

我可以停下来：

/etc/init.d/myapp stop

/etc/init.d/myapp stop

问题在于保存过程的PID，我想我在某处看到了这样做的秘诀，我不记得我和哪里我无法找到它。

The problem is all about saving the PID of the process, I think I saw somewhere a recipe for doing this, I don't remember where and I'm not able to find it.

我看到有一个名为 Java Server Wrapper ，但我寻找一些不限制内存使用的免费软件。我认为这项工作可以在一个bash脚本中完成。

I saw that there is a project called Java Server Wrapper, but I look for something free that does not limit memory usage. And I think that this work could be done in a single bash script.

推荐答案

看看 Apache Commons Daemon 。

它有'jsvc'启动器支持启动并停止基于java的守护进程（服务）。

It has 'jsvc' launcher which suports starting and stopping java-based daemons (services).
