Drupal System Requirements
Here are a few directives that may need tweaking beyond the posted Drupal requirements. I have padded these greatly. You will consume much
less than these limits.

* LimitRequestBody directive in /etc/httpd/conf.d/php.conf increase to 1 GB * post_max_size directive in /etc/php.ini increase to 50M
* upload_max_filesize directive in /etc/php.ini increase to 50M
* memory_limit directive in /etc/php.ini increase to 50M

In addition, you could really use modrewrite on apache. This helps create clean URLs but more importantly helps google index your site
completely. Google has limits on the number of links it will index using url parameters.
