When changes are made to the httpd.conf on a cPanel server, people don’t update the distiller file normally. So when apache is recompiled, the changes are lost. To avoid this, please be sure that you save the changes to the distiller file by running the following;

/usr/local/cpanel/bin/apache_conf_distiller –update –main

This will confirm that the changes were saved and will save the changes to the main distiller config, saving them for the future apache recompilations.

HOLD ON, this is not it yet!!!! We need to get it into PHP rite?

The new WHM has utility to complete the task.

Log into WHM >> Software >> Module Installers >> PHP Pecl and install imagick to get the whole thing binding into PHP.

That should be it, if by any chance you got a problem with a 64 bit OS and WHM can not find imagick then install it manually, by following the steps below

Check if ImageMagick-devel is installed, if not install it using yum.

Then you need to download the Imagick PHP extensions, located here: http://pecl.php.net/package/imagick

cd /usr/src/
wget http://pecl.php.net/get/imagick-x.x.x.tar.gz
tar -zxvf imagick-x.x.x.tar.gz
cd imagick-x.x.x
phpize
./configure
make
make install

Now go back into WHM and try to activate imagick again. That is it You are all done.
