How to divert traffic based on hostname using HAProxy?
- by Bosky
I've had some initial success with HAProxy setting up a bunch of app servers listening on various other ports.
I now have another webserver listening on one port, and i'd like to what changes to make to my config to flow traffic by hostname as well.
The following is the current setup, assuming:
my apache webserver is running at examplecom:8001
my bunch of app servers 0.0.0.0:8081, 0.0.0.0:8082 , 0.0.0.0:8083
global
log 127.0.0.1 local0
log 127.0.0.1 local1 notice
maxconn 4096
debug
#quiet
#user haproxy
#group haproxy
defaults
log global
mode http
option httplog
option dontlognull
retries 3
redispatch
maxconn 2000
contimeout 5000
clitimeout 50000
srvtimeout 50000
listen appservers 0.0.0.0:80
mode http
balance roundrobin
option httpclose
option forwardfor
#option httpchk HEAD /check.txt HTTP/1.0
server inst1 0.0.0.0:8081 cookie server01 check inter 2000 fall 3
server inst2 0.0.0.0:8082 cookie server02 check inter 2000 fall 3
server inst3 0.0.0.0:8083 cookie server01 check inter 2000 fall 3
server inst4 0.0.0.0:8084 cookie server02 check inter 2000 fall 3
capture cookie vgnvisitor= len 32
(any other comments on the ^ setup are welcome.)
Now I'd like to continue the same above, but in addition in case - if the hostname is myspecialtopleveldomain<dot>com, then would like to flow traffic to example<dot>com:8001
