Install Mediawiki

Warning:

Debian packages are currently unmaintained and outdated. This guide will install mediawiki from source. For your security, don't forget to follow upstream releases and update your installation.

Prerequisite

DNS

This guide assume that you are using a dedicated subdomain for your wiki like https://wiki.example.com. Don't forget to point that domain to your webserver.

Database

You will need a database server store all dynamic data (users, articles…). You can check the MariaDB installation guide.

Nginx

In this guide, we will use Nginx as a web server. Please check the Nginx installation guide.

Get source

# cd /var/www
# curl https://releases.wikimedia.org/mediawiki/1.26/mediawiki-1.26.2.tar.gz | tar xz
# chown -R www-data: mediawiki*

Configure Nginx

create certificate

update nginx config

/mw-config

chown root:www-data /etc/mediawiki/LocalSettings.php
chmod 640 /etc/mediawiki/LocalSettings.php

Install Extensions

ParserFunctions

This extension is bundled by default with mediawiki. You just need to activate it.

Add the line wfLoadExtension( 'ParserFunctions' ); to the file /var/www/mediawiki*/LocalSettings.php

SyntaxHighlight

This extension is bundled by default with mediawiki. You just need to activate it.

Add the line wfLoadExtension( 'SyntaxHighlight_GeSHi' ); to the file /var/www/mediawiki*/LocalSettings.php

TemplateData

Speedup

By default the mediawiki installation is pretty slow.

Localisation cache

Uncomment the line about $wgCacheDirectory in /var/www/mediawiki*/LocalSettings.php.

## Set $wgCacheDirectory to a writable directory on the web server
## to make your wiki go slightly faster. The directory should not
## be publically accessible from the web.
$wgCacheDirectory = "$IP/cache";

Enable CronJob

First create the log file

# touch /var/log/mediawiki-runJobs.log
# chown www-data:adm /var/log/mediawiki-runJobs.log
# chmod 640 /var/log/mediawiki-runJobs.log

Then add the following line in /etc/crontab

0  0    * * *   www-data /usr/bin/php /var/www/mediawiki-1.26.2/maintenance/runJobs.php > /var/log/mediawiki-runJobs.log

Finally you can disable jobs running on user visits in /var/www/mediawiki*/LocalSettings.php

# Jobs are run by the cronjob. No need to run them on use visits
# https://www.mediawiki.org/wiki/Manual:$wgJobRunRate
$wgJobRunRate = 0;
