Haporxy : redirect connection to 2nd server if server 1 down and ; to 3rd server when server 2 goes down;
I have layer 4 Haproxy setup with three servers configured as follows :
listen db_rw
bind *:3306
log global
mode tcp
option tcpka
default-server port 9200 inter 2s downinter 5s rise 3 fall 2 slowstart 60s maxconn 1024 weight 100
server server1 192.168.0.101:3306 check
server server2 192.168.0.102:3306 check backup
server server3 192.168.0.103:3306 check backup
Here always server1 is up since others are configured backup until server1 is down; But when server1 is down it will then send request to other two servers 2,3 when server1 is down;
My intension is that, when server 1 is down ; request should be forwarded to server2; when server 2 is down then send request to server 3 only; I am using listen ;
Could anyone tell me how to accomplish this sitation;
I think using acl and *srv_is_up * could be possible;

I Think you have done it right already, have a look at this article : failover-and-worst-case-management-with-haproxy
It seems as though it will only use 1 backup until it fails in turn.
If you want to use both you need to specify option allbackups in backend
