HAProxy "503 Service Unavailable" for webserver running on a KVM virtual machine
- by Menda
I'm setting up a server with KVM (IP 192.168.0.100) and I have created inside of it one virtual machine using network bridging at 192.168.0.194. This virtual machine has an nginx instance running, which I can access from the server or from any computer computer in the internal network just typing in the browser http://192.168.0.194.
However, I try configure HAProxy in the same server that hosts KVM and looking the status page of HAProxy it always shows the virtual machine as "DOWN". If I try from the server http://localhost, it should be the same than if I go to http://192.168.0.194. My goal is to build a reverse proxy, but I tried this little example and won't work. What am I doing bad?
This is my config file in the server:
# /etc/haproxy/haproxy.cfg
global
maxconn 4096
user haproxy
group haproxy
daemon
defaults
log global
mode http
option httplog
option dontlognull
retries 3
option redispatch
maxconn 2000
contimeout 5000
clitimeout 50000
srvtimeout 50000
listen ServerStatus *:8081
mode http
stats enable
stats auth haproxy:haproxy
listen Server *:80
mode http
balance roundrobin
cookie JSESSIONID prefix
option httpclose
option forwardfor
option httpchk HEAD /check.txt HTTP/1.0
server mv1 192.168.0.194:80 cookie A check
Thanks.
