Am 17. Mar, 2014 schwätzte keith smith so: 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, der.hans > Hi I'm looking into how to create a self-signed SSL on CentOS 6.x and the reference I am looking at says I should issue the command :   yum install mod_ssl  . > > I assume mod_ssl would have been installed with Apache.  So I would like to check that.  I looked at the man page for yum and it seems there is no way to check if it is installed. > > How can I check to see if a package or module has been installed? > > Thanks!! > > Keith -- # http://www.LuftHans.com/ http://www.LuftHans.com/Classes/ # "it's not what you do, it's how the whiteboard looks..."
