Re: HAproxy and lvs

Hi John,

As mentioned in the previous thread, LVS lives in the Kernel and works
as a router. HAproxy is userspace and a reverse proxy so a completely
different beast! So to answer your question, no it doesn't.

It seems that HAproxy can also perform TCP load balance.
Does HAproxy leverage lvs when performing TCP load balance?

HAProxy with LVS-DR

[Witold Duranek]

Hi,

I am having small architecture of two apache server with LVS 
loadbalancer in DR mode. I've installed haproxy (1.3.20) in front of 
eache apache server to protect  them against  slowloris with this 
haproxy config:


global
   daemon
   user hpr
   group hpr
   maxconn 2
   pidfile /var/run/haproxy.pid
   stats socket /var/run/haproxy.stat mode 600

defaults
   mode http
   maxconn 4096
   timeout client 60s
   timeout server 60s
   timeout queue  60s
   timeout connect 4s
   timeout http-request 5s
   option httpclose
   option abortonclose
   balance roundrobin
   option forwardfor
   retries 2
   errorfile 503 /usr/local/etc/haproxy/errorfiles/503sorry.http

frontend public
   bind external_ip:80
   default_backend apache

backend apache
   option httpchk OPTIONS * HTTP/1.1\r\nHost:\ www
   server dwww1 127.0.0.1:80 maxconn 248 check port 80

listen stats
   bind   :
   stats enable
   stats hide-version
   stats uri /
   stats realm   dwww1\ statistics
   stats authadmin:admin
   stats refresh 5s

everything seems to be ok, but unfortunately after couple seconds apache 
is stop responding and haproxy send a lot of 503 errors

T / HTTP/1.0

i also trying to disable keepalive and running only one apache server 
(one with haproxy) in LVS with no luck
when i omit LVS everthing works. Does anybody have similar problems with 
running haproxy with LVS-DR ?


Kind regards,
