HAProxy setup for NLS

[judge01]

Hello,

Has anybody implemented HAProxy loadbalancer as frontend for NLS Cluster? i am currently trying to set it up and im having troubles with it. my HAProxy config is below. the problem is that when i hit the balancer, from the balancer logs it shows that both NLS are being connected to and i could not log in successfully to the NLS Page.

global
log 127.0.0.1 local2
chroot /var/lib/haproxy
pidfile /var/run/haproxy.pid
maxconn 4000
user haproxy
group haproxy
daemon
stats socket /var/lib/haproxy/stats

I know it's something that can be done, though we don't have any specific documentation regarding the process. A former co-worker may have left behind some notes I can dig through, but most topics regarding load-balancing are considered out of scope for "official support" at this time.

looking forward to anything that might help. thanks.

His notes didn't provide anything useful unfortunately. We can leave this thread open though in case anyone in the community has anything to offer.
