Install

Version 1.5 was not yet on amd64 feeds but v1.4.x reclaimed php4 so I took mediawiki v1.5 from the i386 feeds as anyway mediawiki is all arch.

  • Raise the PHP memory limit: create /var/lib/mediawiki1.5/.htaccess with
php_value memory_limit 32M

Preventing access to pages

Better solution seems to use this patch:

Or as refered on http://meta.wikimedia.org/wiki/Hidden_pages this one:

Disable anonymous reading

Easy to get:

Customisation

Logo

  • I created a symlink from /var/lib/mediawiki1.5/local to /etc/mediawiki1.5/localdata
  • In LocalSettings.php: $wgLogo = "$wgScriptPath/local/mylogo.png";

Menus

Import/Export

HTML-WikiConverter

apt-get install libhtml-wikiconverter-perl

Dialogs are not yet packaged, cf bugreports 419918 and 448912, so for now: 

perl -MCPAN -e 'install HTML::WikiConverter::MediaWiki'

Here is the script I used to import my phpwiki pages: 

#!/bin//bash


for i in lists/*; do
    mkdir -p $(basename $i)
    cd $(basename $i)
    for p in $(cat ../$i); do
	echo $p
	if [ ! -e "$p.html" ]; then
	    wget -q -O - "http://wiki.teuwen.org/$p" > "$p.html"
	fi
	cat > "$p.txt" <<EOF
''Converted with [[MediaWiki#HTML-WikiConverter|HTML::WikiConverter::MediaWiki]] from my old phpwiki site''
----
EOF
	cat "$p.html"|\
	   awk '
		/class=.wikitext/ {b=1};
		/Begin browse-footer/ {b=0};
		b==1' \
	 | sed 's/<div class="wikitext">//g' \
	 | sed 's/<span style="white-space: nowrap">//g' \
	 | sed 's/<span class="wikipage">//g' \
	 | sed 's/<img src="\/phpwikidata\/themes\/[a-zA-Z0-9]\+\/images\/[a-zA-Z0-9]\+.png" alt="" class="linkicon" border="0" \/>//g' \
	 | sed 's/\x92/\x27/g' \
	 |html2wiki --encoding iso-8859-1 --dialect MediaWiki >> "$p.txt"
#	  >> "$p.txt"
    done
    cd ..
done

Upgrade to 1.11

A big jump from 1.5...
Now the package is simply called mediawiki instead of mediawiki1.x
Strangely apt-get wanted to install mysql-server even if the package just recommends it.
So I downloaded the package and used dpkg -i

Upgrade to 1.12

Debian did a transparent upgrade but things were a bit broken, for some special or unknown pages I got a SQL error about a missing protected_titles table.
Solution is in this bugreport: run 

php /var/lib/mediawiki/maintenance/update.php

Extensions

OpenID support

I installed the following extension:

I installed the extension into /etc/mediawiki/extensions and made a symlink from /var/lib/mediawiki/extensions
I created the extra SQL table: 

mysql -uroot -p mediawiki < openid_table.sql

But I had first to edit openid_table.sql to add my table prefix (cf $wgDBprefix)
I installed php-openid: 

apt-get install php-openid

Some modifications in /etc/mediawiki/LocalSettings.php: 

# Adding /usr/share/php in the include_path to find the Debian php-openid package:
ini_set( "include_path", ".:$IP:$IP/includes:$IP/languages".":/usr/share/php" );
require_once("$IP/extensions/OpenID/OpenID.php");
$wgTrustRoot = "http://wiki.yobi.be/";
$wgOpenIDLoginLogoUrl = "local/login-bg.gif";

(the logo was downloaded from http://www.openid.net/login-bg.gif)

I had to patch the extension as apparently the API of php-OpenID changed since

Normally the extension makes your personal page an OpenID server as well but I didn't try
Now you can login via Special:OpenIDLogin or associate your OpenID URL to your existing account via Special:OpenIDConvert
BTW initially I didn't know about Special:OpenIDConvert and I manipulated directly the SQL table ${wgDBprefix}user_openid

Tips

When developing extensions I had the problem that cached pages didn't get refreshed properly even if they claim it shouldn't concern logged users.
It is possible to force one individual page to be invalidated and refreshed by using ?action=purge
