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.” Click this link and then follow the on screen directions.
The second option is from the command line. Run “/scripts/easyapache”, which will provide an update interface including a few more options than WHM.
It is highly recommended that you create a backup of your Apache configuration before preforming an update to a newer version.
