Apache vHost doesnt work behind HaProxy

JuKu · August 8, 2018, 4:16pm

Hi all together,

i am using HaProxy as proxy for an apache2 webserver setup.
Apache2 is listening on port 8080 and HaProxy is listening on port 80 and 443. I am also using SSL.
If i browse phab.example.com:8080 (domain changed here) everything is working fine, vHosts works and so on.
But if i browse phab.example.com (which requests to HaProxy), i always get the content of /var/www/html and i dont know why.

My HaProxy configuration /etc/haproxy/haproxy.cfg:

gist.github.com

haproxy.cfg

global
	log /dev/log	local0
	log /dev/log	local1 notice
	chroot /var/lib/haproxy
	stats socket /run/haproxy/admin.sock mode 660 level admin
	stats timeout 30s
	user haproxy
	group haproxy
	daemon

phab.example.com (not working, over HaProxy):

I have fixed the problem now!
Apache2 vHosts only listen on public server ip, not on internal 127.0.0.1 ip.
So i have to change backend line server phab1 127.0.0.1:8080 check to server phab1 193.30.xxx.xxx:8080 check.
