Is it ok to leave a self-written server running in screen?

Question

linux

There is a certain server which is manually started through ssh. So that it doesn't crash when I close ssh, I run it in screen.
Are there side effects from this method of starting/running the server? It seems to have not fallen even once in a day, but I want to be 100% sure.

Answer 1

This is fine. When there is nowhere to go (for example, you need to communicate interactively with such a program), this is exactly how they get out of the situation.
By default, you cannot connect to someone else's screen, so from a security point of view, everything is fine.
There are no complaints about stability either.
I have rtorrent and jabber client working in this mode. Uptime will soon exceed 300 days. It hasn’t crashed yet (:
PS. Although if interactive interaction with the server is not expected, then you can run it through nohup.

Answer 2

nohup your_script &
After that won't kill after closing the console.
There are no side effects from screen.

Answer 3

Not normal, these are crutches. Demonize the script.

Answer 4

everything was said correctly above, but why would you leave it in screen(_self-written_)? what if he falls? Will you be checking in every hour? configure monit, logs, daemonize, etc

Answer 5

I usually raise this runit, if it falls down and restarts + rotates the logs

Answer 6

I would make it run through init scripts /etc/rc.d/ and not take a steam bath, even in the same screen'e from your user. So at least when the car is restarted, it will rise by itself
