Hello,

I have 3 servers and on each server is installed nginx and apache. I  
want  
to set these 3 servers load balance each other. One of them will be main  
server that will accept the traffic from clients and balance to the  
other 2  
servers. I have a failover ip that can be switched at any time to the  
other  
2 servers in case that main server fail totally.

So I have a question about nginx configuration related to upstreams  
part.  
Should I proceed that way:

1. On Main server i set upstreas like that:

server 127.0.0.1:8080; (this is apache installed on same machine)  
server server2; (this is second server, on it on port 80 listens  
nginx)  
server server3 backup; (this is third server, on it on port 80 listens  
nginx)

1. On second and third servers i set only 1 upstream:

server 127.0.0.1:8080; (i set only this and not the others to prevent  
loop)

Is this correct way to do it or there is a better way?

Awaiting for your reply.

Thank you in advance.

Best regards,  
Ali
