just posting this because some n00bs always fucks it up and then ask
us how to do it.
So here are the basic steps to install Drupal on Ubuntu using Apache
1) Download Drupal here
2) unpack it into /var/www folder with tar xvzf drupal-XXX.tar.gz (where XXX is the version number)
3) p0wn your /var/www folder with: sudo chown -R your_n00b_username /var/www
4) change permissions for /var/www/sites/default
5) enable clean URL's (http://drupal.org/node/43783)
a) sudo gedit /etc/apache2/httpd.conf add the following
<Directory />
Options FollowSymLinks
AllowOverride all
Order deny,allow
Deny from all
</Directory>
<Directory /usr/share/phpmyadmin>
Options Indexes FollowSymLinks
DirectoryIndex index.php
Order deny,allow
Deny from all
Allow from 127.0.0.1
Allow from 10.0.0.0/24
</Directory>
b) sudo gedit /etc/apache2/sites-enabled/000-default
change: <Directory /var/www/> Options Indexes FollowSymLinks MultiViews
AllowOverride none
to: <Directory /var/www/> Options Indexes FollowSymLinks MultiViews
AllowOverride all
3) sudo a2enmod rewrite; sudo /etc/init.d/apache2 restart
That's it :) See wasn't that hard
