Cpanel -actually- has 2 scripts in /scripts/ folder to check and install ImageMagick. They are /scripts/checkimagemagick to check whether ImageMagick has been installed or not, and /scripts/installimagemagick to install ImageMagick (if you got message ‘missing’ after execute /scripts/checkimagemagick).
After installing ImageMagick through /scripts/installimagemagick, make sure you have enabled imagick in PHP PECL (Module Installer >> PHP PECL . click ‘manage’ button). And then restart apache / httpd
Fiuh.. It was easier than i thought..
