Hello,

I’m novice in HAPROXY, i’am using 1.8 V  
bellow my roundrobin configuration :

=========================  
global  
log /dev/log local0  
log /dev/log local1 notice  
chroot /var/lib/haproxy  
stats socket /run/haproxy/admin.sock mode 660 level admin expose-fd listeners

listen stats  
bind \*:88

stats enable  
stats uri /stats

=============================  
The problem is when i use my Haproxy’s link one time and i see at stats i found that my proxy send tow requests at time for both servers 1 & 2 not in turns as should be in roundrobin mode

Did you have any solution for me ?

Thanks

I’m not sure what you are saying. Can you provide the logs and explain based on the logs the difference between what you see and what you expect?

When i send one http request from my **[LBalanced.link.com](http://LBalanced.link.com)** i have this in my stats :  
 ![lb-after](https://us1.discourse-cdn.com/flex016/uploads/haproxy/original/1X/e26b1390cc4f9205b5ec434594817aef40dee94f.png)

what i expact is to see only 1 request for SERVER1 and 0 request for SERVER2  
So for me Roundrobin is not working and don’t know what wrong with my conf ?!

I assume those are two different requests.

Check the haproxy logs, to get more informations.

Yes this is the problem, when i send one request from my [LBalanced.link.com](http://LBalanced.link.com) logs say that :

Nov 27 10:49:08 localhost haproxy[8981]: My\_@IP:50209 [27/Nov/2018:10:49:08.570] Loadbalancer\_Prod Nodes\_Prod/SERVER1 0/0/1/1/50 200 55719 - - ---- 1/1/0/0/0 0/0 “GET / HTTP/1.1”  
Nov 27 10:49:09 localhost haproxy[8981]: My\_@IP:50209 [27/Nov/2018:10:49:09.112] Loadbalancer\_Prod Nodes\_Prod/SERVER2 0/0/1/2/4 200 55719 - - ---- 1/1/0/0/0 0/0 “GET /favicon.ico HTTP/1.1”

So effectively my loadbalancer re-send 2 requests when i send him only one  
Did you have any idea what can be the root cause ? or at least can you confirm if my config is good ?

Thank you
