Keepalived vrrp_script does not failover - centos

Question

I have 2 nodes with keepalived and haproxy services (CentOS7).
If I'm shutdown one node all working fine. But I want to failover the VIPS if haproxy is down.
This is 1st node config:
vrrp_script ha_check {
script "/etc/keepalived/haproxy_check"
interval 2
weight 21
}
vrrp_instance VI_1 {
state MASTER
interface eno16777984
virtual_router_id 151
priority 101
advert_int 1
authentication {
auth_type PASS
auth_pass 11111
}
virtual_ipaddress {
10.0.100.233
}
smtp_alert
track_script {
ha_check
}
}
2nd node:
vrrp_script ha_check {
script "/etc/keepalived/haproxy_check"
interval 2
fall 2
rise 2
timeout 1
weight 2
}
vrrp_instance VI_1 {
state BACKUP
interface eno16777984
virtual_router_id 151
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 11111
}
virtual_ipaddress {
10.0.100.233
}
smtp_alert
track_script {
ha_check
}
}
cat /etc/keepalived/haproxy_check
systemctl status haproxy | grep "inactive"
When I stop haproxy it still does not failover the VIPs to the next
host.
[root#cks-hatest1 keepalived]# tail /var/log/messages
Nov 30 10:35:24 cks-hatest1 Keepalived_vrrp[5891]: VRRP_Script(ha_check) failed

Nov 30 10:35:46 cks-hatest1 Keepalived_vrrp[5891]: VRRP_Script(ha_check) succeeded
What I am doing wrong? Thank you in advance!

Answer 1

In your script you are checking if
systemctl status haproxy
contains keyword "inactive". Is that the value you get when you stop haproxy service manually?
As soon as haproxy service is stopped your logs contains it is started again. Can you verify that?
Also, try with replacing the script as
script "killall -0 haproxy"

Answer 2

It's easy. Try this for example:
vrrp_script check_haproxy {
script "pidof haproxy"
interval 2
weight 2
}
In the end of config you should add following part too:
track_script {
check_haproxy
}
