Sometimes we may need to save installation packages which are installed by using yum.
This is useful if we want to reinstall the rpm packages when internet is not available .
# vi /etc/yum.conf
Now we have all packages saved in /var/cache/yum directory and we can install all packages including dependencies with the command rpm -ivh *.rpm
# cd /var/cache/yum
#rpm -ivh *.rpm
If any dependencies are missing , we can insert the OS installation disk and type the command ‘ yum localinstall *.rpm’.
#yum localinstall *.rpm
