Re: [Keepalived-devel] vrrp_script doesn't seem to work

[Vonlanthen, E. <Elm...@un...>]

Hello,
 
I see, that on machine 2 the vrrp-script is not defined. So machine 1
has a priority of 121 if everything is ok and machine 2 has a priority
of 100.
 
If the server on machine 1 isn't listening anymore on port 80 the prio
would be 101. But this value is still higher then the prio of machine 2.
(but the configuration with "weight -2" should work)
 
I think that is the problem. But I am not expert.
 
Best regards
Elmar

	Hi,
	    I am trying to configure keepalived on 2 machines using
keepalived 1.1.13 so that if one goes down, the other will take over.
This part seems to work fine.
	    Now I want to further specify that if port 80 on machine 1
is no longer being listened, its priority will be reduced so that
machine 2 can take over.
	    I did that by introducing vrrp_script block into the conf
file on machine 1 as shown below, but it doesn't seem to work. Any idea
why it doesn't work? Thanks.
	
	    Here's the keepalived.conf on machine 1.
	
	! Configuration File for keepalived
	
	global_defs {
	   notification_email {
	     web...@xx...
	   }
	   notification_email_from mac...@xx...
	   smtp_server 127.0.0.1
	   smtp_connect_timeout 30
	}
	
	vrrp_script chk_http_port {
	       script "</dev/tcp/127.0.0.1/80"
	       interval 2
	       !weight -5
	}
	
	vrrp_instance VI_1 {
	    state MASTER
	    interface eth0
	    virtual_router_id 51
