Hi, I have a problem:  
upstream backend {  
server 172.16.0.1:80;  
server 172.16.0.2:80;  
}  
server {  
listen 80;  
server\_name [www.domain.com](http://www.domain.com);  
location / {  
proxy\_pass [http://backend](http://backend);  
}  
}  
Now I have the model as above, but I don’t know can configure to sync  
data between 2 servers? please, help me …

Hardly an nginx problem, but whatever the backends are, use nfs for  
the web space, or push your site code to every backend’s web space.  
Database should be accessible on an internal network.
