How do I upgrade Apache on my Cpanel box?
There are two ways to update your Apache version on cpanel. The first is from within WHM. Underneath the “Software” section in the menubar, is “Apache Update.”
Merely click this link, and then follow the on screen directions. From the command line, you can run /scripts/easyapache, which will provide an interface to update apache that provides a few more options than WHM. Either way, you will want to go ahead and make a backup of your Apache configuration before preforming an update to a newer version.
