[rt-users] Two RT intances in two Apache servers in the same box. Is it possible?

[Bob Goldstein]

If you are going to run 2 apaches on the same box,
you must be running on different ports.


The way I described running 2 RT's on the same apache,
each had it's own set of fastcgi processes.  I suspect
(but haven't tried) that you could actually kill one
set of fastcgi's, without killing the other set.
Apache would restart them, and this would give you
the same affect as restarting apache does now.

(That is, the whole point of restarting apache is
to reload code changes.  If you are using mod_perl,
you need to do this.  But if you are using fastcgi,
the code is loaded into fastcgi, not into apache itself.)
