Below is a list of all the packages required by Mediawiki for installation on Ubuntu.

~$ sudo apt-get update && sudo apt-get install apache2 mysql-server php5 php5-mysql libapache2-mod-php5 ImageMagick php5-intl

Alternatively, if you think you have already installed some of the packages, you can quickly check

Remove anonymous users? [Y/n] y
Disallow root login remotely? [Y/n] y
Remove test database and access to it? [Y/n] y
Reload privilege tables now? [Y/n] y

login to db

~$ mysql -u root -p

Create mysql wiki user

~$ mysql> CREATE USER 'wiki'@'localhost' IDENTIFIED BY 'THISpasswordSHOULDbeCHANGED';
~$ mysql> exit

login as new user to verify account works

~$ mysql -u wiki -p
~$ mysql> exit

~$ mysql -u root -p
~$ mysql> CREATE DATABASE sewikidatabase;

unpack mediawiki in a temp directory

~$ sudo pwd
/home/user/downloads/
~$ sudo mkdir /var/www/html/sitename.com/wiki
~$ tar xvzf mediawiki-1.22.6.tar.gz

Configure Apache2

Since we're going with a subsite configuration, the virutalhost file is going to be simple and only point to the site's root directory

~$ sudo vi /etc/apache2/sites-available/yoursite.com.conf
add:
<VirtualHost *:80>
        ServerName yoursite.com
        ServerAdmin [email protected]
        DocumentRoot /var/www/yoursite.com
        TransferLog /var/log/apache2/yoursite.com-access_log
        ErrorLog /var/log/apache2/yoursite.com-error_log
</VirtualHost>
