• File LocalSettings.inc.php:
  • Enable file upload.
  • Set logo (from http://sneak.co.nz/kiwi/ - resized to 135x135 max)

$wgEnableUploads = true;
...
$wgLogo = "$wgScriptPath/kiwi.png";

• File includes/DefaultSettings.php:

JsMath.

• DEPRECATED — no longer used, replaced by Extension:Math / MathJax (better rendering, more powerful, easier to install, and jsMath is no longer updated).

Math

• DEPRECATED — We don't use this extension anymore, but use MathJax extension instead (which allows for $...$ formulas).
• Configure Math to use MathJax javascript engine for much better results.

require_once "$IP/extensions/Math/Math.php";
// Set this if you don't use MediaWiki Math's texvc:
# $wgTexvc =  '/your/path/to/texvc';

$wgUseMathJax = true; // enabeling MathJax as rendering option
$wgDefaultUserOptions['math'] = MW_MATH_MATHJAX; // setting MathJax as default rendering option (optional)
/**
 * The default parser for MathJax is 'http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML'
 * If you don't want to or can't use the default and your run your own locally
 * replace the below url with something like:
 * $wgMathJaxUrl = '/mathjax/MathJax.js?config=TeX-AMS-MML_HTMLorMML';
 */
$wgMathJaxUrl = 'http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML';
MathJax_Parser::$do_dollar = false;

• First go to Priorweb control panel, MySQL section, and creates new user (see $wgDBname, $wgDBuser and $wgDBpassword above)
• and go to Priorweb mailmanager to create email address (see $wgEmergencyContact)
• then ssh to daemenj@ftp.noekeon.org:

cd kiwi.noekeon.org/
wget http://download.wikimedia.org/mediawiki/1.13/mediawiki-1.13.0.tar.gz
tar -xvzf mediawiki-1.13.0.tar.gz

Version 1.22.1

• Not really an upgrade, but reinstall. Upgrade caused issue with the new short-URL, and our LocalSettings.php was too old.

mv miki oldmiki 
wget http://download.wikimedia.org/mediawiki/1.22/mediawiki-1.22.1.tar.gz 
tar -xvzf mediawiki-1.22.1.tar.gz

cp -iar oldmiki/images miki
cp -iar oldmiki/upload miki
cp oldmiki/kiwi.png miki

• Go to https://kiwi.noekeon.org/miki/index.php, and follow instructions, and install given LocalSettings.php.
  • Enable extension Cite, WikiEditor and SyntaxHighlight.
• Install other extensions

Version 1.28.1

First tentative, install from .tar.gz file. Aborted because of two reasons:

• Tried to install the new mathoid extension.
• Extension GeSHi was not working.

Mathoid

• Reference:

• Mathoid github
• Mathoid mediawiki
• Installing node.js

curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
sudo apt-get install -y nodejs

• Installing npm
• About node modules not found

• None of the install procedure works on Debian Jessie. This is what I did:

# Make sure umask is correct *** IMPORTANT ***
umask 022

# Install newest node.js -- the one of Jessie is much too old for Mathoid
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
apt install -y nodejs
# Install some dependencies
apt install librsvg2-dev
# Install npm *GLOBALLY*, as root, YES AS ROOT, GOSH
# ... Installing as root was the only way to solve the problem of "./app.js" module not found 
npm install -g mathoid
# ... mathoid is installed in /usr/lib/node_modules/mathoid
# ... test that it works:
cd /usr/lib/node_modules/mathoid
node server.js
# ... in a separate shell:
curl -d 'q=E=mc^2' localhost:10044

# Make sure umask is correct
umask 022

# We do a few things (from debian/mathoid.install / debian/mathoid.postinst)
addgroup --system mathoid
adduser --system --home /usr/lib/node_modules/mathoid --no-create-home --disabled-password --ingroup mathoid mathoid
cd /var/log
mkdir mathoid
chown mathoid:mathoid mathoid
chmod 700 mathoid

# If ok, generate the scripts
# We run the script to generate the startup scripts:
mkdir scripts/init
cd scripts/init
../gen-init-scripts.rb .

# Edit the files and copy as necessary

vi debian/mathoid.upstart
vi debian/mathoid.default
vi debian/mathoid.logrotate
vi config.dev.yaml
vi script/init/mathoid.service

cp debian/mathoid.upstart /etc/init/mathoid.conf
cp debian/mathoid.default /etc/default/mathoid
cp debian/mathoid.logrotate /etc/logrotate.d/mathoid
cp config.dev.yaml /etc/mathoid/config.yaml
cp script/init/mathoid.service /etc/systemd/system/mathoid.service

# Test everything is ok
systemctl start mathoid
systemctl status mathoid -l
ss -tupan|grep 10044
curl -d 'q=E=mc^2' localhost:10044

GeSHi

• No rendering, no error, nothing, except category page with highlight problems.
• Actually the issue was that shell_exec and proc_open (and maybe others) was disabled in PHP on server. See Phabricator bug T128993.
• To get debug output, add to LocalSettings.php:

$wgShowExceptionDetails = true;
$wgDevelopmentWarnings = true;
error_reporting( -1 );
ini_set( 'display_startup_errors', 1 );
ini_set( 'display_errors', 1 );

$wgDebugLogFile = "/var/lib/mediawiki/images/debug.log";

• To remove all interfering permissions, check files /etc/php5/apache2/php.ini and possibly files in /etc/php5/apache2/conf.d/, for lines like

disable_functions = shell_exec, escapeshellarg, escapeshellcmd, proc_close, proc_get_status, proc_nice, proc_open, proc_terminate

and clear out everything (doing so MAY EXPOSE YOUR SERVER TO FOREIGN ATTACKS!):

disable_functions =

version 1.27.1

Installed from debian package:

• First, import logo kiwi.png as an image, such that now file is in ./images/e/ea/Kiwi.png.
• Install the package

apt install mediawiki
vi /etc/apache2/conf-available/mediawiki.conf
# Remove Alias /mediawiki /var/lib/mediawiki
vi /etc/apache2/sites-available/www.immie.org.conf
# Add 'Alias /wiki /var/lib/mediawiki'

• Now visit the site and follow instruction. This upgrade the database and generate a new Localsettings.php

cp LocalSettings.php /etc/LocalSettings.php
chown www-data:www-data /etc/LocalSettings.php
chmod 700 /etc/LocalSettings.php
rm LocalSettings.php
cd /var/www
cp -rp --no-clobber /wiki/images /var/lib/mediawiki
mv wiki mediawiki

• Add MathJax.

cd /var/lib/mediawiki/extensions
git clone https://github.com/hbshim/mediawiki-mathjax MathJax
chown -R www-data:www-data MathJax
cd /usr/share/javascript/mathjax/config/local
ln -sf /var/lib/mediawiki/extensions/MathJax/mwMathJaxConfig.js
vi mwMathJaxConfig.js
# Edit URL at the end of the file
vi /etc/mediawiki/LocalSettings.php
# Add Mathjax stuff:
#
# # Extension:MathJax
# wfLoadExtension( 'MathJax' );
# # MathJax location
# $wgMathJaxJS = "/mathjax/MathJax.js";
# # Configuration - see "http://docs.mathjax.org/en/latest/config-files.html"
# $wgMathJaxProcConf = "TeX-AMS-MML_HTMLorMML-full";
# # Local configuration file (excluding .js)
# $wgMathJaxLocConf = "local/mwMathJaxConfig";
# $wgParserCacheType = CACHE_NONE;

Troubleshooting

• See above for GeSHi not running.

Troubleshooting

See MediaWiki - how to debug.

Mainly add to LocalSettings.php:

$wgShowExceptionDetails = true;
$wgDevelopmentWarnings = true;
error_reporting( -1 );
ini_set( 'display_startup_errors', 1 );
ini_set( 'display_errors', 1 );

$wgDebugLogFile = "/var/lib/mediawiki/images/debug.log";

Backup

Some references:

• See Configuration Noekeon.org
• See Mediawiki guide to backup here
  • See also here for complete procedure

My procedure:

• Copy this file to the wiki server, and make it executable.

backup_wiki ([{{#filelink: backup_wiki}} download])

{{#fileanchor: backup_wiki}}

#! /bin/bash

# This script will create a backup of the MySQL databases used in Mediawiki wiki
# The backup is output to standard output (gzipped), so that the backup can easily be transferred
# over an ssh connection for instance
#

   echo "         is the path to the LocalSettings.php file containing the database name, password..."
   echo ""
   echo "Example:"
   echo ""
   echo "  $0 ./LocalSettings.php > ~/backup/wiki-backup.sql.gz"
   echo ""
   exit 1

• Run this script on the machine where the backup files are to be saved (adapt the script to your needs):

~/bin/backup_noekeon ([{{#filelink: backup_noekeon}} download])

{{#fileanchor: backup_noekeon}}

#! /bin/bash

# This script will create a backup of the miki wiki database on noekeon.org
# Backup will be saved in ~/backup

BACKUPDIR=~/backup
WIKINAME=www.noekeon.org_miki
FSQLNAME=$BACKUPDIR/wiki-$WIKINAME-$(date '+%Y%m%d').sql.gz
FFILENAME=$BACKUPDIR/wiki-$WIKINAME-$(date '+%Y%m%d').tar.gz

mkdir -p $BACKUPDIR

echo "Backing up the MySQL database to '$FSQLNAME'..."
ssh noekeon '~daemenj/private/backup_wiki ~daemenj/kiwi.noekeon.org/miki/LocalSettings.php' > "$FSQLNAME"

echo "Backing up the files & extensions to '$FFILENAME'..."
ssh noekeon 'cd ~daemenj/kiwi.noekeon.org; /usr/bin/nice -n 19 tar -cz miki/' > "$FFILENAME"

To restore a MediaWiki backup on a local LAMP server (see also [3] for DB creation, and [4] for MySQL restore command):

MYSQL_HISTFILE=/dev/null  mysql --user=root -p mysql

mysql> CREATE DATABASE mikiwiki;
mysql> GRANT ALL PRIVILEGES ON mikiwiki.* TO miki@localhost IDENTIFIED BY '********';
mysql> quit

#Restore the wiki files
sudo mkdir /var/www/miki
cd /var/www/miki
sudo tar --strip 1 -xvzf ~/backup/wiki-20091111-www.noekeon.org_miki.daily.tar.gz
sudo chown -R www-data /var/www/miki
sudo chgrp -R www-data /var/www/miki
#Edit /var/www/miki/LocalSettings.php to match current config
sudo vi /var/www/miki/LocalSettings.php
# ... $wgDBserver="localhost"

# Restore the SQL backup (! note that mikiwiki is not the password, but the db name !!!):
gunzip < wiki-20091111-www.noekeon.org_miki.daily.sql.gz | mysql -u miki -p mikiwiki
# ... enter password for user miki

To Do

• DONE — Upgrade jsMath to MathJax (see also [5]) (this requires MediaWiki 1.19 or higher)
