[Zope] The best way to set up Multiple Zopes?

ProxyPass is certainly a nice clean way to do it.  Since you are 
already using Virtual Hosts this should be no problem - just set up 
a VHost for each site.

If you want distinct zope installations then configure each one to 
run with a separate port base (eg. 8000, 7000, 8100, 8200).  
Conceptually you want to assign a block of 100 ports to each zope 
installation, out of this block zope uses the ports it wants (xx21 ftp, 
xx80 http, xx99 monitor).

Finally, proxy pass each VHost to localhost:xx80/

Not with multiple zopes, but with a combination of zope and other 
http servers on the same machine and the principle is the same, 
although it won't be too long before we are running multiple zopes.

Obviously, each instance of zope is going to require another set of 
resources (memmory, disk, i/o).


Are you sure you need multiple zopes?  Or could you run each site 
inside a directory in one zope with, say, a SiteRoot product in each 
one?

Cheers,
Stephen
