– Install Prerequisites:

sudo apt-get install apache2-dev libtool git

Git clone the mod_clouflare repo from cloulflare:

cd ~/
git clone https://github.com/cloudflare/mod_cloudflare.git
cd mod_cloudflare

Use the Apache extension tool to convert the .c file into a module:

apxs -a -i -c mod_cloudflare.c

Restart Apache:

sudo apachectl restart

Verify that the module is active:

apache2ctl -M|grep cloudflare

The output should show “cloudflare_module (shared)“

Now your apache logs should show the real client IP instead of the cloudflare IPs.

tail -f /var/log/apache2/access.log

-Below is screenshot of access log that shows the real client IP(right click and open image in new lab for high res image):
