keepalived 脚本不执行 报SECURITY VIOLATION - scripts are being executed but script_security not enabled.

查看/var/log/messages keepalived相关日志，查看提示，是否没有权限，script_security not enabled

1、确认脚本可以手动执行，是否有执行权限，脚本第一句需要加#!/bin/bash

2、keepalived配置文件是否省略了global_defs {}，本地测试省去这段脚本不会执行，

加上后虽然还提示SECURITY VIOLATION - scripts are being executed but script_security not enabled.

但是脚本执行了，查看/var/log/messages 可看到 VRRP_Script(chk_mysql) succeeded
