推荐答案

大多数Unix/Linux init程序将为您管理守护程序并重新启动它们.考虑将服务放置在/etc/inittab中.或者您可能正在使用Upstart或systemd.

Most of the Unix/Linux init programs will manage daemons for you and restart them. Look into placing your service in /etc/inittab. Or you might be using Upstart or systemd.

所有这些程序均以PID 1身份运行，监视和重新启动系统进程是他们的工作.

All of these programs run as PID 1 and it is their job to monitor and restart system processes.

从您的Busybox标记中，我假设您正在运行嵌入式系统.在这些系统上，System V风格的初始化脚本及其所有的shell脚本实在是太过分了.您可能应该删除所有内容，并用/etc/inittab或upstart或systemd作业中的条目替换.

From your Busybox tag I would assume you are running an embedded system. On those, the System V style init scripts with all of their shell scripts are really overkill. You should probably rip all that out and replace it with entries in /etc/inittab or upstart or systemd jobs.
