A FreeBSD 11.2-RELEASE was installed on a PCEngines box to host a DokuWiki server. To install and configure DokuWiki, the following steps were perfored.

Install DokuWiki and Apache.

sudo pkg install dokuwiki
sudo pkg install apache24

Edit the config file of system environment (for booting next time) for Apache (2.4): add in /etc/rc.conf

apache24_enable="YES"

comment out/edit /usr/local/etc/apache24/httpd.conf

#DocumentRoot "/usr/local/www/apache24/data"
DocumentRoot "/usr/local/www/dokuwiki"

<Directory "/usr/local/www/dokuwiki">
	Options Indexes FollowSymLinks
	DirectoryIndex index.php
	AllowOverride None
	Require all granted
</Directory>

Install PHP module

sudo pkg install mod_php71

check if the LoadModule line was added

cat /usr/local/etc/apache24/httpd.conf | grep php

should output

LoadModule php7_module        libexec/apache24/libphp7.so

add in /usr/local/etc/apache24/httpd.conf

<IfModule php7_module>
        DirectoryIndex index.php index.html
        AddType application/x-httpd-php .php
        AddType application/x-httpd-php-source .phps
</IfModule>

change the owner of conf and data in /usr/local/www/dokuwiki/ to the web server.

sudo chown -R www:www /usr/local/www/dokuwiki/conf
sudo chown -R www:www /usr/local/www/dokuwiki/data

restart FreeBSD

open wiki install.php in browser

http://192.168.178.65/install.php

enter data, for example

Wiki Name: nplab
Superuser: admin
E-Mail: timo.voelker@fh-muenster.de
Initial ACL policy: Closed Wiki

after that /usr/local/www/dokuwiki/conf/local.php contains the configuration

create directory outside of the installation path

sudo mkdir -p /var/dokuwiki/www

move data and conf into /var/dokuwiki/www. Move bin directory into /var/dokuwiki

sudo mv /usr/local/www/dokuwiki/data /var/dokuwiki/www/
sudo mv /usr/local/www/dokuwiki/conf /var/dokuwiki/www/
sudo mv /usr/local/www/dokuwiki/bin /var/dokuwiki/

set owner of /var/dokuwiki/www to www

sudo chown -R www:www /var/dokuwiki/www

create inc/preload.php

sudo vi /usr/local/www/dokuwiki/inc/preload.php

and add

<?php

// among other things. For more information on this issue, please see:w
// http://www.dokuwiki.org/devel:coding_style#php_closing_tags 
define('DOKU_CONF','/var/dokuwiki/www/conf/');

add in /var/dokuwiki/www/conf/local.php

$conf['savedir'] = '/var/dokuwiki/www/data';
