keepalived 腳本不執行 報SECURITY VIOLATION - scripts are being executed but script_security not enabled.

查看/var/log/messages keepalived相關日誌，查看提示，是否沒有權限，script_security not enabled

1、確認腳本可以手動執行，是否有執行權限

2、keepalived配置文件是否省略了global_defs {}，本地測試省去這段腳本不會執行，

加上後雖然還提示SECURITY VIOLATION - scripts are being executed but script_security not enabled.

但是腳本執行了，查看/var/log/messages 可看到 VRRP_Script(chk_mysql) succeeded
