I was trying to run a MediaWiki instance on my dummy server and wanted to serve it using the Caddy this time. Apache and Nginx configurations are fairly straightforward and easy to find, but Caddy -since it’s fairly new- could be difficult if you are trying to do some non-standard stuff. As I have successfully executed it with the desired configuration, I wanted to document my observations.

Configuration has two parts, one being the standard Caddyfile which I really like to work with, and the other one being LocalSettings.php This file is generally in the root folder of your mediawiki which is the default setup file for MediaWiki instances.

Serving a PHP application through Caddy is straightforward, but I wanted to configure my installation with the so-called ShortURLs. This requires some setup in the Caddyfile:

your.domain{
    @title {
        not file {
            try_files {path} {path}/
            split_path .php
        }
        path_regexp title ^/(.*)$
    }
    rewrite @title /index.php?title={re.title.1}&{query}
    root * /var/www/html/mw #this might be mediawiki for you
    php_fastcgi unix//var/run/php/php-fpm.sock # serving php applications
    file_server
}

This configuration redirects the ugly MediaWiki URLs to a more structured /wiki/Main_page type. Further explanations are here.

After that you need to edit the LocalSettings.php too:

$wgScriptPath = "";
$wgArticlePath = "/wiki/$1"; #for redirecting to
/wiki/ $wgUsePathInfo = true;

Reload the Caddy config:

caddy reload --config /etc/caddy/Caddyfile

Done.
