Hi,this is Ichiro.  
When I used nginx as a load balancer, I want to set the connection limit  
of an individual server.

ex)---------------------------------------------  
upstream 192.168.1.1 {  
server 192.168.11.1:80; ← 100 conn/sec  
server 192.168.11.2:80; ← 100 conn/sec  
}

## total 200 conn/sec

It is not a connection limit of the entire VirtualServer[192.168.1.1],  
and I want to set it to an individual server[192.168.11.[1,2]].

Is such a setting possible?  
Would you teach this setting method?

Regards.

Hi!

You need a third party module ( [NGINX 3rd Party Modules | NGINX](http://wiki.nginx.org/3rdPartyModules) )  
such as EY Balancer: [http://github.com/ry/nginx-ey-balancer/tree/master](http://github.com/ry/nginx-ey-balancer/tree/master)

Hello Ensiferous.  
Thanks you!

I read explanation of EY Balancer, so understood that I just matched a  
purpose.  
I’m tring to install that soon!

Kind regards,  
Ichiro

Hi.  
This is Ichiro.

I installed EY Balancer Module.  
So I looked like to be finished this problem.  
This problem seemed to be over.

However, a problem occurred one more…

The queue beyond max\_connections is kept waiting forever.  
I tuned up ”max\_connections\_module.c", but behavior does not change.

Can you throw away connection beyond the “max\_connections” to  
sorry\_server?

ex)---------------------------------------------  
\*nginx.conf  
upstream 192.168.1.1 {  
server 192.168.11.1:80; \<- 1 conn/sec  
server 192.168.11.2:80; \<- 1 conn/sec  
max\_connections 1  
}

_max\_connections\_module.c  
if (conf == NULL) return NGX\_CONF\_ERROR;  
max\_connections\_rr\_index = 0;  
conf-\>max\_connections = 1;  
conf-\>max\_queue\_length = 10; /_ default max queue length 10000 _/  
conf-\>queue\_timeout = 10; /_ default queue timeout 10 seconds \*/  
return conf;
