Your request is showing a troubling trend among posters on this list.
Many do not make use of the fabulous search engines provided by the
likes of Yahoo, Microsoft, or Google.

The other trend is that many do not bother to look at installed documentation.

Please do a "man yum.conf" and "man yum" to learn about the most
important utility in your toolbox. Then edit /etc/yum.conf and change
the value for "installonly_limit"
