This will serve as a quick reminder to myself that Debian behaves a little bit differently than Ubuntu when it comes to DNS resolving (in my defense, I have been working a lot on Ubuntu lately).
So, one of my Debian VMs had stopped resolving hostnames and I kept looking into /etc/network/interfaces to see if the correct DNS server was listed there. And it was. But that’s not the place to put DNS server information in Debian.
The big advantage of using Debian for a DokuWiki install is that this distro has a simplified install process over other distributions, as both the installation and the upgrade of the software are completely handled by Debian’s package manager.
In additon to this, there is an advantage by using DokuWiki over some other heavier wiki software such as, for example, MediaWiki: it is structurally simple. Everything, from configuration files to pages content, lies in simple text files. That’s right, no need for a database or anything else, just a simple folder and file structure. This also makes it very easy to update, restore and migrate DokuWiki installs should you need to.
Therefore, if you need a wiki up and running quickly, these are the instructions on how to install DokuWiki on Debian 8.
