Cpanel has a lot of supporting software that you may be using on your server. In case something goes amiss, here is a list of scripts that reinstall cpanel-provided software on your system. For most all of these, you can pass a –force as an argument to force a reinstall of the application.

Update: Most of the scripts that were previously mentioned in this post have been deprecated and/or change over time. We will do our best to keep this list updated.
