At our lab, we have several services handled by different phd students (like myself). Fluctuation is high and people do the job next to their research duties. Until now, services were running on different machines, with different OS setups that can result in administration hell quickly.
We want to consolidate our service setup. Our main idea is that the guys responsible for the services should not meddle with the underlying system anymore. Apart from core systems like NFS and kerberos, a typical service is able to run as non-root already. I'm talking about apache, mysql, subversion, mail with openxchange, and so on. Redirecting privileged ports is also no issue (source).
What is left is the configuration of the service and its payload. One scenario we envisioned is that every service has its own user and home directory, accessable by the corresponding admins. Backup and fallback of the service is easy, as everything needed for the service to run is found in one place.
Are there established ways to create
such a setup?
Does a mostly unique
method exist to make services find
their files (other than in system
directories) while still using the
corresponding debian packages?
Are there any catches with our idea that
we may have overlooked?
Would you
maybe claim that virtualization is
the answer to our problem? (In our
POV, it wouldn't help us keeping system
setup strictly separated from service
setup.)
Thank you for any advice!
