Checking if mod_ssl is installed

moin moin Keith,

you already answered about how to install via yum list.

You also need to make sure it's enabled. Not sure that Red Hat follows
the mods-available / mods-enabled model, but I believe it does. If so, you
need to symlink from mods-enabled to mods-available for mod_ssl. You might
have a2enmod available. Don't know if it does anything other than safely
create the link.

ciao,
