Virtual IP can not achieve the master switchover

[xchkun]

Hi,
Through keepalived nginx master and backup, but the main nginx lost, the virtual IP will not drift to nginx, configured as follows:
10.10.14.9 The host hosts the main nginx and keepalived containers
10.10.14.8 The host has prepared nginx and keepalived containers
keepalived configure:
global_defs {
default_interface ens33
}

#vrrp_script chk_nginx {

script "/etc/keepalived/check_nginx.sh"

interval 2

weight -5

fall 3

rise 2

#}

vrrp_instance VI_1 {
interface ens33

track_interface {
ens33
}

state MASTER
virtual_router_id 51
priority 100
nopreempt

unicast_peer {
10.10.14.8
10.10.14.9
}

virtual_ipaddress {
10.10.14.16
}

authentication {
auth_type PASS
auth_pass 1111
}

track_script {

chk_nginx

}
