Yum Package Manager
Yum is an automatic updater and package installer/remover for rpm systems. It automatically computes dependencies and figures out what things should occur to install packages. It makes it easier to maintain groups of machines without having to manually update each one using rpm. Yum has a plugin interface for adding simple features. Yum can also be used from other python programs via its module inteface.

The cPanel & WHM update script (/scripts/upcp)
This script handles most of the updates on your cPanel & WHM system. You can run this script in 2 ways:
* On the command line, by entering /scripts/upcp as the root user.
* In WHM, using the Upgrade to Latest Version feature at Main >> cPanel >> Upgrade to Latest Version.
In addition to updating cPanel & WHM, this script also updates most of the software on your system by calling a number of other scripts within the /scripts directory.
Cpanel software update scripts description
In addition to /scripts/upcp
Update System Software Updates your system software. This script is essentially the same as running yum update.
Update Server Software Updates software dependencies required by cPanel that are provided by the operating system.
There are a number of scripts that update applications installed with cPanel.
cpanelsync’s Exclude Functionality
Setting cPanel-distributed files to immutable will cause a variety of problems. If you wish to prevent cPanel from updating certain files, do not make the files immutable. Instead, enter those files’ paths in /etc/cpanelsync.exclude.
Each entry in the /etc/cpanelsync.exclude file must use a fully specified path, with each path on its own line.
For example, if you wish to prevent the following files from updating:
/usr/local/cpanel/scripts/pkgacct
/usr/local/cpanel/Cpanel/Logd.pm
Add the files’ paths to /etc/cpanelsync.exclude using the following 2 commands:
echo “/usr/local/cpanel/scripts/pkgacct” >> /etc/cpanelsync.exclude
echo “/usr/local/cpanel/Cpanel/Logd.pm” >> /etc/cpanelsync.exclude
Note: This method only prevents the cpanelsync utility from updating files. It does not prevent updates that occur at application runtime. You cannot use cpanelsync.exclude to prevent modifications to configuration files, datastores, or similar types of files.
