Hi!

I have an application that needs to be run on multiple virtual hosts  
(Apache2) with each instance having it’s own environment / database.  
Using dispatch.cgi I simply configure two virtual hosts pointing to the  
same application path and just add a “SetEnv RAILS\_ENV  
\<environment\_name\>” to each virtual host section in the Apache  
configuration. But with FastCGI / dispatch.fcgi this doesn’t work.

Any ideas how to run multiple instances (each having a different  
database) of the same application with Apache and FastCGI?

Regards,

Tobias

I am doing something similar, but with lighttpd. Rails automatically  
handles different environments with different databases. Just set them  
up in database.yml.

The basic config looks like:

$HTTP[“host”] == “[www.mydomain.com](http://www.mydomain.com)” {  
server.document-root = “/home/mydomain/public/”  
fastcgi.server = (  
“.fcgi” =\>  
( “localhost” =\>  
(  
“socket” =\>  
“/home/lighttpd/var/run/lighttpd-fcgi-mwprod.socket”,  
“bin-path” =\> “/home/magneticworld/public/dispatch.fcgi”,  
“bin-environment” =\> ( “RAILS\_ENV” =\> “production” ),  
“max-load-per-proc” =\> 25,  
“min-procs” =\> 1,  
“max-procs” =\> 4,  
“idle-timeout” =\> 30  
)  
)  
)  
}

$HTTP[“host”] == “[dev.mydomain.com](http://dev.mydomain.com)” {  
server.document-root = “/home/mydomain/public/”  
fastcgi.server = (  
“.fcgi” =\>  
( “localhost” =\>  
(  
“socket” =\>  
“/home/lighttpd/var/run/lighttpd-fcgi-mwdev.socket”,  
“bin-path” =\> “/home/magneticworld/public/dispatch.fcgi”,  
“bin-environment” =\> ( “RAILS\_ENV” =\> “development” ),  
“max-load-per-proc” =\> 25,  
“min-procs” =\> 1,  
“max-procs” =\> 4,  
“idle-timeout” =\> 30  
)  
)  
)  
}

2 sites, 2 environments, 2 dbs, running from the same root.

Thanks! That’s exactly what I want to do. It’s just, that I want to do  
it with Apache2. It seems I can’t set different fcgi servers with  
different environments for each virtual host in Apache.

No Apache-Rails-Guru around?
