Here’s my quick howto on installing GNUPG PHP Pecl extension (pecl docs) in Cpanel. Please note that this covers only the installation process and no further details on setting up gpg keys or using the function with extension or sample PHP scripts.
Installation process is very straightforward provided you met the requirements like php-pear, gnupg, libgpg-error, and gpgme. You can install it directly from
WHM -> Module Installers -> PHP Pecl, enter
gnupg and click the Install button. You can do the same via shell with this command
pecl install gnupg. Then restart your Apache. Be sure to double check if the extension was added to you
On Cpanel servers most of the requirements are present, like
php-pear (if you compiled your apache/php with pear),
gnupg, libgpg-error, etc, except for gpgme which is the main library used by
gnupg extension. Our system is running CentOS 4.7 with latest STABLE branch of Cpanel (S35075 at this time of writing), PHP 5.2.9 with pear and libgpg-error (version 1.0-1 only). Only missing requirement was
gpgme which i installed from source as it was not available on our default yum repository. You can also install it from other repositories like
centos.karan.org. At this time the latest
gpgme version is 1.1.8 but I installed version 1.1.2 because it’s the latest version compatible with our libgpg.
I also encountered an error library path when I check the extension,
so I had to add
/etc/ld.so.conf and run
ldconfig, so that libraries in this directory are detected automatically.
