Installation Overview
All instructions done on Oracle Linux 6.5
Below are instructions for setting up a single instance of mediawiki on a server, however i've specifically included certain instructions in order to easily allow for multiple instances of mediawiki on the same server. If you want to configure multiple instances, once done with the the configuration below, you can go to the Multiple Instances page.

configure apache
make a backup of the default httpd.conf
~$ sudo cp /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.conf.default
make sure that the following is in your httpd.conf and is NOT commented out

give folder rights to apache user
~$ sudo chown -R apache:apache /var/www/html/servername/mediawiki-1.22.6/
verify
~$ ls -la /var/www/html/servername/ total 12 drwxr-xr-x. 3 root root 4096 Apr 28 14:52 . drwxr-xr-x. 3 root root 4096 Apr 28 15:16 .. drwxr-xr-x. 13 apache apache 4096 Apr 24 17:24 mediawiki-1.22.6
restart apache and finalize install
~$ sudo service httpd restart
Browse to your site's URL
it will let you know no LocalSettings.php file was found and give you a link to begin installation. This install script asks you a bunch of questions and will generate the LocalSettings.php based on your responses.
Save the LocalSettings.php file and copy to your site's directory, which in this case was:
~$ /var/www/html/servername/mediawiki-1.22.6/
If you opted for Image Uploads, it would have asked for which directory deleted files will go in, by default it is /var/www/html/servername/mediawiki-1.22.6/images/deleted/, so do the following:
~$ sudo mkdir /var/www/html/servername/mediawiki-1.22.6/images/deleted/ ~$ sudo chown apache:apache /var/www/html/servername/mediawiki-1.22.6/images/deleted/
Restart Apache
~$ sudo service httpd restart
Reload the page and your wiki should be operational or at least ready for further configuration.
