Installation

On Unix Debian based (so Ubuntu as well), do the following: 

mkdir /var/www/sites/domain.co.uk
cd /var/www/sites/domain.co.uk
wget http://download.wikimedia.org/mediawiki/1.20/mediawiki-1.20.2.tar.gz
tar xvzf mediawiki-*.tar.gz
cd mediawiki-1.20.2
mv mediawiki-1.20.2/* .
mv .gitreview .jshintignore .jshintrc ..
apt-get install mysql-server build-essential
apt-get install php5-mysql php-pear php5-dev php5-gd php5-imagick php5-intl libcurl3-openssl-dev libicu-dev gobjc++
pecl install intl
apt-get install memcached libmemcached-dev php-auth php-mail php-mail-mime
pecl install Memcache
pear install net_smtp
vim /etc/php5/apache2/php.ini # you need Apache installed first)
# as well as
vim /etc/php5/cli/php.ini
/Dynamic

Add in the following lines: 

extension=intl.so
extension=memcache.so
memcache.hash_strategy="consistent"

Choose a caching software between APC and xcache. If you want APC, use this. If you want xcache, do: 

apt-get install php5-xcache
memcached -u root -d -m 2048 -l 10.0.0.40 -p 11211
/etc/init.d/apache2 restart
cd /var/www/sites
chown root:root domain.co.uk/ -R
cd /var/www/sites/domain.co.uk
chmod 700 LocalSettings.php
apt-get install qmail

Then check this: http://www.mediawiki.org/wiki/Manual:Config_script

And go to domain.co.uk/index.php and run through the configuration. Then download the LocalSettings.php file.

http://www.mediawiki.org/wiki/Manual:Securing_database_passwords

Account confirmation

http://www.mediawiki.org/wiki/Extension:ConfirmAccount

Upload the .tar.gz to /var/www/sites/domain.co.uk/extensions 

tar -xzf ConfirmAccount.tar.gz
vim LocalSettings.php
require_once("$IP/extensions/ConfirmAccount/ConfirmAccount.php");

Exit the file and run php maintenance/update.php

To turn off "Your biography must be at least 50 words long.", as this does not use $wgAccountRequestMinWords any more: 

vim /var/www/sites/domain.co.uk/extensions/ConfirmAccount/ConfirmAccount.config.php

Edit: 

'Biography'       => array( 'enabled' => true, 'minWords' => 50 ),

If you get the below error when approving an account: 

Could not create directory "mwstore://accountcreds-backend/accountcreds-public/1/12/123".
chown www-data:www-data images/ -R
chmod 755 images/ -R

Also check your "$wgFileExtensions = {'gif', 'png');" entry

You may need to create an array, something like this:

$wgFileExtensions = array('gif','png');

Capitalise headers and tab titles

vim domain.co.uk/skins/monobook/main.css 

.portlet h5 {
        background: transparent;
        padding: 0 1em 0 .5em;
        display: inline;

        font-size: 91%;
        font-weight: normal;
        white-space: nowrap;
}
.portlet h6 {
        background: #ffae2e;
        border: 1px solid #2f6fab;
        border-style: solid solid none solid;
        padding: 0 1em 0 1em;
/*      text-transform: lowercase; /* force text to lowercase */

        text-transform: capitalize; /* force text to proper case */
        display: block;

        text-transform: capitalize;
#p-cactions li a {
/*      text-transform: lowercase; */
        text-transform: capitalize; /* force text to proper case */
}

require_once("$IP/extensions/ConfirmEdit/ReCaptcha.php"); 
$wgCaptchaClass = 'ReCaptcha';
$wgReCaptchaPublicKey = 'your public key here';
$wgReCaptchaPrivateKey = 'your private key here';

Short URL configuration

http://www.mediawiki.org/wiki/Manual:Short_URL 

vim LocalSettings.php
$wgScriptPath       = "";
$wgArticlePath      = '/wiki/$1';
$wgUsePathInfo      = true;
$wgScriptExtension  = ".php";
a2enmod rewrite
/etc/init.d/apache2 restart
vim /etc/apache2/sites-available/domain.co.uk
    RewriteEngine On

Old edited Special:AllMessages

"To protect the wiki against automated account creation, we kindly ask you to solve the simple sum below and enter the answer in the box (more info):"

with the following extract from /extensions/ConfirmEdit/ReCaptcha.i18n.php

"To help protect against automated page creation, please type the two words you see in the box below (more info):"

Migrating to a new server

On the original server, do this: 

mysqldump --default-character-set=binary --user=root --password=EnterPasswordHere databasename > dbdump.txt

Then copy all your content and the dbdump.txt file across to the new server.

To delete a useless database, do this from within MySQL: 

DROP DATABASE wikidb;

You will need to create an empty database first: 

create database DatabaseName;

Then on the new server do: 

mysql --silent --local --password=EnterPasswordHere DatabaseName < dbdump.txt

Go into MySQL and create the MySQL user from the old server (specified in LocalSettings.php on the original server) by doing: 

create user 'DatabaseUser'@'localhost' identified by 'password';
GRANT ALL PRIVILEGES ON DatabaseName.* TO 'DatabaseUser'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION ;

Edit your LocalSettings.php to ensure the following setting are correct:

$wgDBtype = "mysql"; $wgDBserver = "localhost"; $wgDBname = "DatabaseName"; $wgDBuser = "DatabaseUser"; $wgDBpassword = "DatabaseUserPassword*";
