如何保护我的进程不被杀死? [英] how to protect my process from being killed?

问题描述

我们在Linux上有一个关键任务服务器程序，我们不希望其他人意外终止它.如果有人将其终止或崩溃，我们希望它重新启动.

We have a mission-critical server program on top of Linux and we don't want others to terminate it accidentally. If somebody terminates it or it crashes, we want it to restart.

因此，我们计划编写另一个程序，例如程序B.我们希望程序B和服务器程序相互保护.如果我们的服务器程序退出，程序B将重新启动它.如果程序B终止，则服务器程序将再次启动它.但是，我们没有一种好的机制可以让程序B和服务器程序在其对等项退出时得到通知.

So we plan to write another program, say program B. We want program B and the server program to protect each other. If our server program exits, program B will restart it. If program B terminates, the server program will start it again. But we don't have a good mechanism that would let program B and the server program be notified when its peer exits.

推荐答案

您可以使用init来照看该进程，并且由于init仅在重新启动时终止，因此您不需要程序B".

You can use init to babysit the process, and since init only terminates on reboot, you don't need a "program B".

添加到/etc/inittab的末尾:

Add to the end of /etc/inittab:

x:3:respawn:/path/to/my/program

有关语法和其他选项的信息，请参见man inittab

For information on syntax and other options can be found in man inittab
