[SOLVED] Mirror software packages from one server to another

szboardstretcher · 01-03-2011, 01:01 PM

Server A is running Centos 5.5, Server B is running Centos 5.5.

What is the simplest way to grab the package list from Server A, and use yum/rpm to make sure that the same packages are installed on server B, and if not -- install them?

Code:

rpm -qa --qf "%{NAME}\n" | tr '\n' ' ' > /tmp/packages.txt

Transfer over packages.txt

Code:

yum install $(cat packages.txt)

(Actually, I wonder if `rpm -qa --qf "%{NAME} "` will work, making the tr unnecessary. Don't have a RedHat-based distro in front of me)
