keepalived 配置高可用notify_master或者notify_backup不执行脚本

用keepalived配置了一个主备tomcat，配置文件如下：

! Configuration File for keepalived
global_defs {
    notification_email {
        [email protected]
        [email protected]
    }
    notification_email_from [email protected]
    smtp_server mail.example.com
    smtp_connect_timeout 30
    router_id LVS_DEVEL
}
vrrp_script chk_tomcat {
    #script "killall -0 nginx"
    script "/etc/keepalived/tomcat_check.sh"
    interval 2
    weight -5
    fall 3  
    rise 2
}
vrrp_instance VI_1 {
    state MASTER
    interface eth0
    mcast_src_ip 192.168.128.150
    virtual_router_id 51
    priority 100
    advert_int 2
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        192.168.128.152
    }
    track_script {
       chk_tomcat
    }

notify_master "/d/d_ctl.sh start"
notify_backup "/d/d_ctl.sh stop"

}

切换时，脚本始终不执行，过google了半天，发现有一个这样写到：

 原文链接：https://serverfault.com/questions/709428/track-script-doesnt-work-after-keepalived-update

chcon -t keepalived_unconfined_script_exec_t /etc/keepalived/chk_available.sh

我的是这样执行：（主keepalived和备keepalived都执行）

chcon -t keepalived_unconfined_script_exec_t  /d/d_ctl.sh

再重启keepalived测试，完全解决
