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，我使用它来启动它

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开始使用的内容:

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

/etc/init.d/myapp start

/etc/init.d/myapp start

我可以停止:

/etc/init.d/myapp 停止

/etc/init.d/myapp stop

问题在于保存进程的 PID，我想我在某处看到了这样做的方法，我不记得在哪里，也找不到.

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 的项目，但我寻找不限制内存使用的免费内容.而且我认为这项工作可以在单个 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.

它具有jsvc"启动器，支持启动和停止基于 Java 的守护进程(服务).

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