Linux yum command skip updating packages

Q. How can I skip any packages updating while using yum update command in CentOS / RedHat / RHEL / Fedora Linux server system?

A.yum command under RedHat / Centos has the -x or --exclude option. It will exclude a specific package by name or shell glob (* or ?) from updates on all repositories.

yum exclude package syntax

Use the following syntax ( you must login as the root user to use following commands):
yum -x {package-name} update
yum --exclude={package-name} update

For example, exclude httpd or kernel package from update, enter:
# yum -x httpd* update
# yum --exclude=kernel* update
For further information read yum command man page:
$ man yum
