Installing with yum from a text file.
To install a list of specific packages that are installed on one server to another server .
rpm -qa > installed.txt
will create a text file with a list of all installed packages
copy installed.txt from server1 using rsync to server2, like this:
rsync installed.txt server2:
then on server2 type
yum -y install $(cat installed.txt)
This will now install all the packages listed in installed.txt on server2.
