Re: Multi server package management

[wagnerc@plebeian.com (Chris Wagner)]

Here's what we did for a 500+ node cluster.  2 approaches depending on
need/time.

1) sync all ssh keys so u don't need a password.  Then do a foreach script
to run the command remotely via ssh <command>.

2) all nodes export a nfs directory which is also a cron run-parts
directory. so anything put there is run as a job.  a central server(only)
has write to the dir, mounts via automounter and copies in scripts that do
whatever maintenance is required. the job should be self deleting so it
doesn't run again.  this system is called crondrops.  the whole thing is
scripted, very neat.
