配置文件内容
[root@localhost ~]# more /etc/keepalived/keepalived.conf 
! Configuration File for keepalived
! extra script call demonstration
! scripts are supported in Instance and groups
! declarations.
global_defs {
    router_id localhost
}
vrrp_script check_run{
    script "/opt/test.sh"
        interval 5
}
vrrp_sync_group G1 {
  group {
    VI_1
  }
}

vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 51
    priority 90
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass admin123
    }
        track_script{
            check_run
        }
    virtual_ipaddress {

}

脚本很简单
[root@localhost opt]# ./test.sh
hello

查看日志,无法绑定VIP

但是如果将keepalived.conf 中的
        track_script{
            check_run
        }
这三行注释掉,又能绑定VIP。查看日志如下:
[root@localhost opt]# vi /etc/keepalived/keepalived.conf

! declarations.
global_defs {
    router_id localhost
}
vrrp_script check_run{
    script "/opt/test.sh"
        interval 5
}
vrrp_sync_group G1 {
  group {
    VI_1
  }
}

vrrp_instance VI_1 {
    state BACKUP
    interface eth0
    virtual_router_id 51
    priority 90
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass admin123
    }
#       track_script{
#           check_run
#       }
    virtual_ipaddress {

}

无论换了哪个版本,都是一样。脚本也chmod 777了。iptables和selinux都已经关闭。求哪位大神帮忙解决下。
