Intranet/Intranet Installation

WORK IN PROGRESS

Introduction
This page documents installing Mediawiki from git, some basic customisation and an upgrade process.

Filesystem layout
By following this procedure, the directory structure you end up with is like this:

Pre requisites

 * Install PHP modules
 * Install git
 * Imagemagick (for image thumbnails) See https://www.mediawiki.org/wiki/Manual:Installing_third-party_tools
 * Setup database

Mediawiki
Check what version Wikipedia is using with https://en.wikipedia.org/wiki/Special:Version You might also want to check here: https://phabricator.wikimedia.org/source/mediawiki/branches/

Find a version using git ls-remote: Clone the chosen version Update the submodules and Composer managed libraries

Web based Installer
This is just the initial install. We will change the URL to access MW later. Browse to https://wiki.example.co.uk/mediawiki Keep the settings to a minimum and don't enable any modules. All of this can be changed later. At the end, download the provided LocalSettings.php file and upload it to the web server's filesystem at /var/www/html. Finally symlink to it from the wiki folder. cd /var/www/html/mediawiki ln -s /var/www/html/LocalSettings.php Disable the MinervaNeue skin in LocalSettings.conf to get the wiki to load until it is no longer dependent on MobileFrontend - see: https://www.mediawiki.org/wiki/Skin:Minerva_Neue. Edit LocalSettings.php and towards the end put a # in front of wfLoadSkin( 'MinervaNeue' );  #### REVIEW

Short URLs
Add a couple of Aliases to the virtual host definition. These are for the final desired short URLs: Change $wgScriptPath and add $wgArticlePath in LocalSettings.php to match the short URL: Browse to https://wiki.example.co.uk and check https://wiki.example.co.uk/wiki/Special:Version to make sure it all looks OK.

Logo
Copy a logo file into /var/www/html and rename it to logo.gif (or.png or whatever) and reference it in LocalSettings.php

Cache
This enables a simple filesystem based cache which will help speed up page load times. Create a cache directory for the wiki to use: Add this to LocalSettings.php:

Cronjob for update.php
Add the following to LocalSettings.php to disable runjobs (see https://www.mediawiki.org/wiki/Manual:Job_queue ) Add this to crontab (change the timings to suit - this example runs every seven minutes) Create a directory for the log When you are happy that runJobs is working correctly then either use something like logrotate to handle the ever growing log file or disable it by removing the redirection in crontab.

Enable wikieditor
Edit LocalSettings.php and add this at the bottom see https://www.mediawiki.org/wiki/Extension:WikiEditor Try editing a page. if the editor does not appear then hold down shift and press the reload button in your browser to clear the cached page.

Authentication and authorisation

Updating
WORK IN PROGRESS

By maintaining the link to the code via a symlink and using more to ensure that we don't lose images and settings by accident we can switch versions quickly  $ cd /var/www Now find a version using git ls-remote and check it out with git clone git ls-remote --heads https://gerrit.wikimedia.org/r/p/mediawiki/core git clone --depth=1 --single-branch --branch wmf/1.27.0-wmf.4 https://gerrit.wikimedia.org/r/p/mediawiki/core.git wmf/ 1.27-wmf.4 Update the submodules cd wmf/1.27-wmf.4 git submodule update --init --recursive Fix up paths (note that you must use the real path here because symlinks can have some surprising behaviour). You will have to remove the images directory first if it already exists. ln -s ../../logo.gif rm -rvf images ln -s ../../images|4=ln -s ../../LocalSettings.php Switch to new code by removing and re-pointing the symlink. If this wiki is running on a virtual machine, now is a good time to snapshot it. cd /var/www rm wiki ln -s wmf/1.27-wmf.4 wiki Run update.php /usr/bin/php /var/www/wiki/maintenance/update.php Now test the new code
