If you don’t intend to come to cPanel, Inc for support about unsupported customizations, feel welcome to perform any customization you desire (e.g. preventing MySQL upgrades from cPanel/WHM). After all, it is your server.

I know there are customers that have performed very interesting customizations to cPanel/WHM including running it on unsupported distributions, adding load balancing functionality and so forth. While we do not provide support for such things or assist in creating such functionality, we’re not going to actively try to stop you from doing those things either – as long as it doesn’t violate the EULA of course. That’s what most people use our community forums for anyway, for assistance from fellow users regarding customizing cPanel/WHM beyond what is supported .

I know experienced SysAdmins prefer having control over our software rather than attempt to operate within the constraints of the software’s GUI and command-line interfaces. If you ever need any assistance with doing something to control the way cPanel operates (e.g. adding something to the account creation routines, integrating administrative functions with a custom web app etc.), you now have my direct email address – feel free to contact me at any time or drop by the community forums.
