= Wiki software =
Wiki software allows an organization to have a manual that can be edited by a number of collaborators. Wikipedia is the best known example.

=== MediaWiki ===
[http://www.mediawiki.org MediaWiki] is the free, open source server software that Wikipedia uses. It is scalable to very large uses. It runs on the [[#LAMP server installation|LAMP server stack]] (which uses the MySQL database and is available as an installation option with the (K)ubuntu [[#Servers|server]]), or it can be used with a postgreSQL database. Installation instructions are [http://www.mediawiki.org/wiki/Manual:Running_MediaWiki_on_Ubuntu here]. Also see these <!--->[http://ubuntudoctorsguild.dyndns.org/mediawiki/index.php/MediaWiki tips]<--->[[MediaWiki_tips|tips]]. Install from the repositories:
 sudo apt-get install mediawiki

*Edit the config file so it recognizes MediaWiki:
 sudo nano /etc/mediawiki/apache.conf

Uncomment (remove the #) the line:
 Alias /mediawiki /var/lib/mediawiki

*Restart apache2:
 sudo /etc/init.d/apache2 restart

*Run/install MediaWiki by logging into:
 <nowiki>http://localhost/mediawiki</nowiki>

:You will be prompted for configuration variables to be set. The trickiest is the MySQL user/password. Hopefully you remember your MySQL superuser that you set at the time of LAMP (or MySQL) installation.

*Copy your local settings configuration file to /etc/mediawiki (and make a backup of the original):
 sudo cp /var/lib/mediawiki/config/LocalSettings.php /etc/mediawiki
 sudo mv /var/lib/mediawiki/config/LocalSettings.php /var/lib/mediawiki/config/LocalSettings_at_install.php

Edit your configuration variables there:
 sudo kate /etc/mediawiki/LocalSettings.php

*If you are using a virtual host server, make a symbolic link (named in this example ''mywiki'') from your /usr/share/mediawiki installation folder to your /var/www folder:
 sudo ln -s /usr/share/mediawiki /var/www/''mywiki''

then make sure you have an apache2 virtual hosts configuration file (in /etc/apache2/sites-available) that points to /var/www/''mywiki'' as the DocumentRoot. Make a symbolic link from your virtual host configuration file in /etc/apache2/sites-available to /etc/apache2/sites-enabled to enable it. Restart apache2 after enabling the sites. (Warning: MediaWiki is not secure at installation and can be easily hacked by new users. Do not publish your wiki to the Internet before reading all the instructions and changing the configuration file (LocalSettings.php) so that it is more secure.)  
You would then access the database at:
 <nowiki>http://my.virtualwikihost.org</nowiki>

*How do I import a copy of Ubuntuguide into my own wiki?

==== ReCaptcha ====
[http://recaptcha.net/learnmore.html ReCaptcha] is a webservice [http://en.wikipedia.org/wiki/CAPTCHA CAPTCHA] module to present a text challenge for user-input that is unreadable by computer bots, lessening the chance of automated input (spam and vandalism). This can be used for wikis and for other uses. <!--->Install the perl library:
 sudo apt-get install libcatcha-recaptcha-perl<--->

A reCaptcha plugin for MediaWiki is available [http://recaptcha.net/plugins/mediawiki/ here] (and instructions are repeated below).

*Download and install:
 cd /var/lib/mediawiki/extensions
 sudo wget -O currentrecaptcha.zip <nowiki>http://recaptcha.googlecode.com/files/recaptcha-mediawiki-1.7.zip</nowiki>
 sudo unzip currentrecaptcha.zip
 sudo rm currentrecaptcha.zip

*Sign up for a private/public key pair from the [https://admin.recaptcha.net/accounts/login/?next=/recaptcha/createsite/%3Fapp%3Dmediawiki ReCaptcha] website.

*Edit the Mediawiki LocalSettings.php file (assuming you put it in /etc/mediwiki):
 sudo nano /etc/mediawiki/LocalSettings.php

:and add the following lines:
 #For ReCaptcha
 require_once( "$IP/extensions/recaptcha/ReCaptcha.php" );
 # Sign up for these at <nowiki>http://recaptcha.net/api/getkey</nowiki>
 $recaptcha_public_key = ' ''xyxyxyxyxyxyxyxyx'' ';
 $recaptcha_private_key = ' ''ababababababababa'' ';

::where ''xyxyxyxyxyxyxyxyx'' is the public key obtained in the previous step and ''ababababababababa'' is the private key.

Now ReCaptcha should appear automatically for new user sign-ups, anonymous edits that contain new external links, and brute-force password cracking attempts.
