Try this guy as a test, Gorakhnath? ( I suspect either user haproxy cannot
bind that port or -- maybe more likely? -- that the listening ip is
incorrect)
# cat /etc/haproxy.cfg.quicktest
global
log 127.0.0.1 local0
log 127.0.0.1 local1 notice
#log loghost local0 info
maxconn 4096
#debug
#quiet
#user haproxy
#group haproxy
defaults
log global
mode http
option httplog
option dontlognull
retries 3
option redispatch
maxconn 2000
contimeout 5000
clitimeout 50000
srvtimeout 50000
listen webfarm
bind :80
mode http
stats enable
stats auth jhon:x
balance roundrobin
cookie JSESSIONID prefix
option httpclose
option forwardfor
option httpchk HEAD /check.txt HTTP/1.0
server webA 192.168.1.34:80 cookie A check
server webB 192.168.1.41:80 cookie B check
Then
# haproxy -f /etc/haproxy.cfg.quicktest
Double checking the interface is good if the above does not work:
# ip addr
regards!
