Save yum packages for later offline installation

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
