Here is how to install Drupal on a Centos5 Linux installation, hosted on http://RimuHosting.com

1. log in as root
2. Update to latest version with: apt-get update ; apt-get upgrade
3. Install modules with: yum -y install php-mysql mod_auth_mysql mysql-server php-gd php-mbstring
4. Enable .htaccess: cp /etc/httpd/conf/httpd.conf httpd.sav
vi /etc/httpd/conf/httpd.conf and change AllowOverride None to All
5. Restart apache with: service httpd restart
6. Now setup MySQL: mysqladmin -u root password rootsqlpassword
7. Make sure mysqld and httpd start on boot by checking the boxes: webmin / system / bootup and shutdown
8. Download your preferred version of Drupal and unarchive it with: tar -zxvf drupal-x.x.tar.gz
9. Move drupal to a suitable directory: mv nameofdrupalfolder /var/www/drupal
10. Make directories for contrib modules and themes:
mkdir /var/www/modules
mkdir /var/www/themes
11. For a single site setup, /var/www/html is the root, so cd /var/www/html
12. Link to copy of Drupal with
    ln -s /var/www/drupal/includes includes
ln -s /var/www/drupal/misc misc
ln -s /var/www/drupal/modules modules
ln -s /var/www/drupal/profiles profiles
ln -s /var/www/drupal/scripts scripts
ln -s /var/www/drupal/themes themes
cp /var/www/drupal/* .
cp /var/www/drupal/.* .
cp -R /var/www/drupal/sites .
ln -s /var/www/themes sites/all/themes
ln -s /var/www/modules sites/all/modules
13. Make files directory and give the installer access to the sites directory:
mkdir /var/www/html/files
chmod 777 /var/www/html/files
chmod 777 /var/www/html/sites/default
14. Create a database (e.g. called drupal) using: webmin / servers / mysql
15. visit the server's root web page and complete the installation using Drupal
16. Secure sites access: chmod 775 /var/www/html/sites/default
17. Well done! You are finished
