How to make it so that after the abnormal termination of the process - this process will start again?

Question

linux

I'm making a server by lane and it would not hurt me to learn how to restart the process if it crashed. I used cron to start the server when the machine starts. Every day it completes the process and starts again at a certain time. Also, the file that starts the server also starts the screen ts session in order to see what is happening on the server. Is it possible to do this: if a certain session disappears, does the command to run this file run again?

Answer 1

You write a daemon
In Linux, systemd is now in charge of daemons, so create a unit that restarts on error
