Did haproxy recognize server2 was down? With thgis configuration the backup keyword needs to be removed from serverBKP (because the rule is implemented with a use_backend directive), this was wrong in my earlier config. Lukas
Re: ACL HAPROXY (check servers UP and DOWN) and redirect traffic
Hi Lukas,
Thanks for the reply and willingness to help.
I did a test and it didn't work. I dropped the server2 interface and only
server1 was UP.
Traffic continues to exit through the main bakend. My wish is that the
traffic is directed to the backup server.
Any tips?
Thank you very much.

Re: ACL HAPROXY (check servers UP and DOWN) and redirect traffic
Hello,
I suggest you put your backup server in a dedicated backend and select
it in the frontend. I guess the same could be done with use-server in
a single backend, but I feel like this is cleaner:
frontend haproxy
option forwardfor
bind server.lab.local:9191
use_backend backup_servers if { nbsrv(backend_servers) lt 2 }
default_backend backend_servers
backend backend_servers
server server1 192.168.239.151:9090 check
server server2 192.168.239.152:9090 check
backend backup_servers
server serverBKP 192.168.17.2:9090 backup

ACL HAPROXY (check servers UP and DOWN) and redirect traffic
Can anyone help me? How to create an ACL to use the backup server if a server goes DOWN. So, if the two backend servers are UP, I use the registered servers. If one (only one) becomes unavailable, traffic is directed to the backup server. Below my settings. frontend haproxy option forwardfor bind server.lab.local:9191 default_backend backend_servers backend backend_servers server server1 192.168.239.151:9090 check server server2 192.168.239.152:9090 check server serverBKP 192.168.17.2:9090 backup Thank you for your help --
