Keepalived: virtual IP appear in both node trouble and track scripts seem not working
 
Hi everyone

I have 2 servers Redhat 5.7. Both of them are installed Keepalived 1.2.1 just for fail over

My issue is: when i start keepalived, both node have the vitual IP, even they saw VRRP instance and VRRP priority of each other. And the VRRP scripts seem not work.

My purpose for the track scripts is: if 1 port service down, keepalived will assign the vitual ip for the other node

Here is my keepalived configuration is Master:
global_defs {
notification_email {
root
}
notification_email_from root
! smtp_server 192.168.200.1
smtp_connect_timeout 30
router_id 12
}

vrrp_script chk_1 {
script "</dev/tcp/127.0.0.1/8384"
interval 1
weight -110
}

vrrp_script chk_2 {
script "</dev/tcp/127.0.0.1/161"
interval 1
weight -110
}

vrrp_instance VI_1 {
state MASTER
interface bond1
virtual_router_id 50
priority 120
advert_int 1

track_interface {
bond1 weight -150
}

track_script {
chk_1
}

authentication {
auth_type PASS
auth_pass 121
}

virtual_ipaddress {
10.211.4.105/192
}
}

vrrp_instance VI_2 {
state MASTER
interface bond0
virtual_router_id 59
priority 120
advert_int 1

track_interface {
bond0 weight -150
}

track_script {
chk_2
}

authentication {
auth_type PASS
auth_pass 122
}

virtual_ipaddress {
192.168.6.23/24
}
}

And the configuration in node 2:

global_defs {
notification_email {
root
}
notification_email_from root
! smtp_server 192.168.200.1
smtp_connect_timeout 30
router_id 12
}

vrrp_script chk_1 {
script "</dev/tcp/127.0.0.1/8384"
interval 1
weight -110
}

vrrp_script chk_2 {
script "</dev/tcp/127.0.0.1/161"
interval 1
weight -110
}

vrrp_instance VI_1 {
state SLAVE
interface bond1
virtual_router_id 50
priority 90
advert_int 1

track_interface {
bond1 weight -50
}

track_script {
chk_1
}

authentication {
auth_type PASS
auth_pass 121
}

virtual_ipaddress {
10.211.4.105/192
}
}

vrrp_instance VI_2 {
state SLAVE
interface bond0
virtual_router_id 59
priority 90
advert_int 1

track_interface {
bond0 weight -50
}

track_script {
chk_2
}

authentication {
auth_type PASS
auth_pass 122
}

virtual_ipaddress {
192.168.6.23/24
}
}

Hi Trung and All

I have same problem, both machines took the VIP on the keepalived. I saw this thread treat solved but I can't find any solution.

Would you let me know the answer?

Regards,
Andy
