1. The following line is coming from an earlier bookmarked tutorial (not sure if it is needed anymore)
apt-get install mediawiki-math
2. Download Math extension from this link
3. Then you should extract the archive in the "extensions" folder within your MediaWiki installation directory.
4. Next, you need to add the following line to your LocalSettings.php file:
require_once("$IP/extensions/Math/Math.php");
sudo apt-get install ocaml cd extensions/Math/math make
6. The next step is to execute the "maintenance/update.php" script via shell:
php maintenance/update.php
Done. Go to test it. [Tested on mediawiki 1.22 on Ubuntu 12.04]. Navigate to "Special:Version" on your wiki to verify that the extension is successfully installed.

Auto timeout & php.ini
See
- http://www.mediawiki.org/wiki/Manual_talk:Configuration_settings#Auto-Logout
- https://www.mediawiki.org/wiki/Manual:FAQ#…do_I_get_logged_out_constantly?
- https://superuser.com/questions/204905/mediawiki-increase-session-timeout
On ubuntu, change /etc/php5/apache2/php.ini.
session.cache_expire=180 session.gc_maxlifetime = 1440 session.cookie_lifetime = 1440
After modifying php.ini, you need to restart apache. sudo /etc/init.d/apache2 restart
Colored font
See https://meta.wikimedia.org/wiki/Wiki_color_formatting_help for a list of common used colors.
<span style="color: red"> ..... </span>
Syntax highlight
Use the "syntaxhighlight" (for newer versions of mediawiki) or source (for older versions) tag for inline/non-inline syntax highlight. For example,
library(d3Network)
Source <- c("A", "A", "A", "A", "B", "B", "C", "C", "D")
Target <- c("B", "C", "D", "J", "E", "F", "G", "H", "I")
NetworkData <- data.frame(Source, Target)
d3SimpleNetwork(NetworkData, height = 800, width = 1024, file="tmp.html")
can be created by
<source lang="rsplus">
library(d3Network)
Source <- c("A", "A", "A", "A", "B", "B", "C", "C", "D")
Target <- c("B", "C", "D", "J", "E", "F", "G", "H", "I")
NetworkData <- data.frame(Source, Target)
d3SimpleNetwork(NetworkData, height = 800, width = 1024, file="tmp.html")
</source>
Note for some reason, when I use the syntaxhighlight tag (use syntaxhighlight instead of source tag), 'r' is not recognized on my mediawiki 1.22 although 'bash' works.
This syntax highlight extension package https://github.com/artemklevtsov/MediaWiki-SyntaxHighlight seems more complete. It supports markdown, cpp, r, bash, cxx, ... (no Fortran?) languages. But highlight.js library supports even more.
favicon
Move favicon.ico to the mediawiki folder and include the following line in the <LocalSettings.php>
$wgFavicon = "$wgScriptPath/favicon.ico";
Note that the attribute of the ico file has to be at least 644. If not, just run the following line
chmod 644 favicon.ico
To download a favicon, use the approach here. For example, to download the favicon icon from https://wiki.ubuntu.com/ website, we just open the url https://wiki.ubuntu.com/favicon.ico.
The approach works is based on the assumption that the favicon.ico file name is not changed and usually located under the website root directory.

- Alternative PHP Cache (php-apc)
In summary:
1. Install php-apc. sudo apt-get install php-apc
2. nano LocalSettings.php. Change $wgMainCacheType from CACHE_NONE to CACHE_ACCEL.
$wgMainCacheType = CACHE_ACCEL;
3. (optional) sudo /etc/init.d/apache2 reload
Article size and its limit
By default the size is 2048 KB. You can modify it in LocalSettings.php.
$wgMaxArticleSize = 100; # 100 KB
To view what the size of the current (and other revisions) of the page is, open the page on the frontend and view its history.
