I have installed mediawiki at home and it has worked without issues. But recently I changed ip addresses of my rasperry pi's so it would make more sense. raspberry-pi-1 would get 192.168.1.101 and raspberry-pi-2 would get 192.168.1.102, etc.

The mac addresses are entered into the home router to lock it down, so the raspberry pi's are still set up for dynamic ip's. Not sure if it's relevant.

But now when I go to the mediawiki page like http://192.168.1.101/mediawiki, it takes a long time because it tries to redirect to http://192.168.1.2/mediawiki/index.php/Frontpage, which was the old url for the frontpage. It should redirect to 101 and not 2. It's with every redirect, like after making a change to a wiki page to save it, the change is saved, but then it times out because it is redirecting to the old ip again.

The system is Ubuntu Server 21.04. I am not sure if this is a linux- or mediawiki-issue.

It turns out that the ip was located in the settings file called LocalSettings.php. It is autogenerated, so I wasn't aware.

The file is located in /var/lib/mediawiki/LocalSettings.php

And what needs to be changed is this.

$wgServer = "192.168.1.1.2";
