Rolling Apache Logfiles
This is a little snippet I whipped up long ago to roll our logs, feel free to use...
The weblog_rotate.pl is a script from Uthe Urchin folk, available at http://download.urchin.com/support/weblog_rotate.pl

PHP on mod_fcgid with Apache2 and mod_suexec
This took a little doing and some major tweaking. Assuming you have the LoadModule line already...
Add the handler for php files, specify the wrapper (in this case the file in the root of the site) and setup connect and communication timeouts. The timeouts are in seconds and you need to set it like that or higher or else file uploads will timeout and I have heard of issues with Wordpress if you don't increase it.
And in php.fcgi...
This should look familiar to another post...
There isn't a definition for suexec in terms of executable location. There doesn't have to be. Apache will automatically wrap it properly. This configuration is far easier than mod_fastcgi and works just as well. Probably easily expanded to work with ruby on rails although I havn't tried yet...

Block Blacklisted Bandwidth Thieves from Hotlinking Your Image Files
Code for an .htaccess file located in a directory containing images (or any other type of file for that matter) to which you want to block hotlinking from blacklisted websites.
Alternate last line to simply block the images from being hotlinked instead of serving a replacement image:
RewriteEngine On RewriteCond %{HTTP_REFERER} ^http://(www\.)?evilwebsite\.com [NC,OR] RewriteCond %{HTTP_REFERER} ^http://forum\.evilwebsite\.com [NC,OR] RewriteCond %{HTTP_REFERER} ^http://(www\.)?bandwidththieves\.net [NC] RewriteRule \.(jpeg|jpg|gif|bmp|png|JPEG|JPG|GIF|BMP|PNG)$ http://example.com/pwnt.gif [L]
example.com/pwnt.gifis the location of the file you want to serve in place of the hotlinked image. Mine just says 'PWNT'.
Alternate last line to simply block the images from being hotlinked instead of serving a replacement image:
RewriteRule \.(jpeg|jpg|gif|bmp|png|JPEG|JPG|GIF|BMP|PNG)$ - [F]
Parse .html files as PHP
To parse files with a .html extension as PHP, add this line to httpd.conf, your VirtualHost container, or .htaccess:
You can substitute your own arbitrary file extensions for .html if you want to use, for example, filename.foo on your site.
AddHandler application/x-httpd-php .html
You can substitute your own arbitrary file extensions for .html if you want to use, for example, filename.foo on your site.
Disallow serving of PHP pages if mod_php is not loaded
If mod_php doesn't load for some reason, your PHP files may be served unparsed, as plain text. This presents the possibility that your database passwords or other senstive information may be visible. Adding the following to your httpd.conf, VirtualHost container, or .htaccess file will deny access to any PHP files if the PHP module is not loaded.
<IfModule !mod_php4.c> <FilesMatch "\.php$"> Order allow,deny Deny from all Allow from none </FilesMatch> </IfModule>

Turn off (mostly) useless apache modules
When I first ported my old Php app to Textdrive, I got all manners of weird errors. Many of these were from weird Apache modules that are enabled by default here.
My solution was to turn off most of these things in my .htaccess file. Here it goes:
