[lvs-users] misc_check healthchecker question

[T Billings <stabilizr1@xxxxxxxxx>]

Hi,

I'm trying to load balance to some mysql servers using Keepalived/LVS and am 
having some issues getting the health checker to work.   I've configured each 
real server with a misc_check healchecker which is a script that does runs 
through some tests and returns a 0 for success and 1 for failure.  Problem is 
that when it returns a 1 keepalived does not remove the system from service.   
What am I missing?  Below is what is currently in my keepalived.conf but I've 
also had misc_timeout and misc_dynmic in there as well as weight = 1 defined 
before the misc_check.

Thanks in advance for your help.


virtual_server 123.45.67.80 3306 {
        delay_loop 30
        lb_algo rr
        lb_kind DR
        protocol TCP

        real_server 123.45.67.81 3306 {
                MISC_CHECK {
                        misc_path /etc/keepalived/bin/db_check.sh
                        }
        }
}
