How often should you reboot a production webserver?
(hexbear.net)
Specifically, a dedicated server running Debian 12.
After a monthly sudo apt upgrade? (Is a monthly upgrade even necessary?)
Never? (unless there is a security update?)
Edit: I may be missing kernel upgrades. Those are probably good... I can't remember if I installed a LTS kernel. I imagine it would be unsecure to post an exact kernel version, however.
A lot of times I'll run
apt-get update/apt-get upgradeon my server and there will be no updates to install. I only reboot if there is a new kernel or something. Otherwise, I can just restart whichever services are directly impacted by the updates.Debian Stable is a rock. Nothing ever changes. I do recommend subscribing to the debian-announce and debian-security-announce mailing lists though.
Nothing ever happens (in Debian).
