Hi All,
We are considering using RoR as the framework for our collection of
sites. Everything looks good so far in our evaluation of RoR, except
for one issue. We have 1000+ sites that are all identical except for
their database and a few customer media files. We would like to have
one install of RoR serve all of our sites, rather than creating 1000+
RoR installs.
For some context, currently we are considering running apache2.2 with
mod_proxy_balancer to mongrel, but very open to suggestions. So we
could set up vhosts to proxy the sites to mongrel. Once mongrel
received the request, somehow come up with a rails context that would
connect it to that sites database. Or some such mechanism...
So that is the goal. I have not evaluated all of the possible options
on how this might be done, but two come to mind as I begin my work:
1) It appears that I can set the rails environment in the
environment.rb file, and that I can connect that environment name to a
database in the database.yml file. So could I somehow select the
environment from the requested url with some fancy lookup code or
translation (ie. www.test.com uses database www_test_com) in the
environment.rb file or a custom environment in the environments
directory? I am not sure exactly when the environment files are
executed? Are they only executed once in the "** Starting Rails with
development environment ..." startup step of mongrel.
2) Can we somehow use Mongrel::Rails::RailsConfigurator::rails method
and set the environment there based on the requested url? Somehow hook
into mongrel using -S script or a plugin of some kind?
3) I sincerely hope someone has a better answer because the above sound
to me like total hacks, and very unlikely to work.
Thanks for any input in advance. I am completely new to rails and ruby,
so please forgive my ignorance.
Cheers,
James Pellow
