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.
