Hi all.  
I guess I am not the first to encounter this…  
I want to deploy some rails apps, using only one domain  
([www.mydomain.com](http://www.mydomain.com)), so that [www.mydomain.com/app1/](http://www.mydomain.com/app1/)… will be mapped to  
the app1 directory,  
[www.mydomain.com/app2/](http://www.mydomain.com/app2/)… will be mapped to the app2 directory.

I would like to use nginx + mongrels  
I couldn’t figure out how to express this in the nginx config file.  
I did something like :

http {  
.  
.  
.

# cluster serving app1

upstream mongrel1 {  
server 127.0.0.1:7000;  
server 127.0.0.1:7001;  
}

# cluster serving app2

upstream mongrel2 {  
server 127.0.0.1:8000;  
server 127.0.0.1:8001;  
}

server {  
.  
.  
.  
location /app1 {  
.  
.  
.  
proxy\_pass http://mongrel\_app1;  
}

location /app2 {  
.  
.  
.  
proxy\_pass http://mongrel\_app2;  
}  
}

}

But this doesn’t work, I get error messages in the production.log files  
because the app1 / app2 prefixes are stll there for rails to figure out.

Thanks for your help

Nadav

Thanks man, this was the problem. I added the prefix option to  
config/mongrel\_cluster.yml in each of the applications directories and  
now it works fine.

Cheers
