系统启动时，使用rc.local文件启动程序是否正确? [英] Is it correct to use the rc.local file to start a program when the system starts?

问题描述

我想在系统启动时启动Java程序(class)(即使没有用户登录时).我阅读了一些文档，发现Linux在引导时执行了init命令，并在rc.d目录中执行了脚本.最后执行rc.local文件.因此，我想知道在系统完成启动后编辑此文件以运行应用程序是否正确?

I want to start a java program ( class ) when the system starts ( even though when no user has logged in the system ). I read some documentation and I found that Linux executes the init command when booting and executes the scripts in the rc.d directory. And the rc.local file is executed last. So I wonder if it is right to edit this file in order to run an application when the system has finished booting up ?

推荐答案

这要视情况而定.如果您的程序

It depends. If your program

• 是纯粹的本地修改，并且
• 您不需要守护程序来控制软件(稍后在系统运行时启动/停止它)，并且
• 一个简单的SIGTERM足以在系统关闭时停止程序，

然后是的，rc.local只是放置它的要点.

then yes, rc.local is just the point to put it.

如果打算在其他系统上安装该文件，请将文件放在/etc/init.d中，并使用系统特定的命令使它在适当的运行级别运行.

If you intend to install the file on other systems, put a file in /etc/init.d and use the system specific commands to let it run at the appropriate runlevels.
