Hi. I maintain a network of ~80 FC7 machines. The machines are a
mix of hardware types, but (ideally) have identical packages
installed. However, often a machine will deviate from the ideal for
a variety of reasons (e.g., it was offline when the user requested
the package). I would like to be able to specify the packages to be
installed in a central location, and have packages install/uninstall
when this list changes.
My primary use case is when I have a user request a package be
installed on all the workstations, typically something that is
already in the Fedora "everything" repository. I don't install
everything by default, but there are additions that are made
periodically. Right now I have scripts to ssh into each machine and
do the install. But this breaks down when there is a machine offline
for some reason (e.g., turned off and waiting for a Dell service rep
to stop by).
There is a Debian package called pkgsync (http://packages.debian.org/
unstable/admin/pkgsync) that appears to do this for apt/dpkg.
Pkgsync appears to allow an admin to maintain a list of "must have",
"may have", and "may not have" packages, and have the installed
packages on a given client periodically synchronize to this list.
But I have found nothing similar for yum.
I know there are tools such as cfengine and puppet that could do this
for me. But they have a steep learning curve, and if possible I'd
rather find a simpler way to do this.
