VPN管理系统freeradius奇怪问题

这几天在给新买的linode部署服务器，弄了VPN（pptp+L2TP),为了方便管理，弄了FreeRADIUS+daloRADIUS.

目前的状况是
1.VPN:PPTP和L2TP均正常
2.设置了一个二级域名做为daloRADIUS web管理页面
已经可以登录并且可以添加新用户，添加新user后，在数据库（Mysql)的userinfo也有显示
3.但是bug就是
调用radiusd -X 始终无法运行，提示的是

意思就是sql的模块没有加载，本来这个是可以在/etc/raddb/radiusd.conf通过
取消注释 $INCLUDE sql.conf 可以修正，可是现在时已经修正了，依旧显示这个问题。
服务器reboot也试过了还是显示这个问题。
现在真的是郁闷了找不到是哪里的问题了，搜索相关关键字，英文中文资料都翻遍了，大概就是这几个方案
1.取消注释 $INCLUDE sql.conf （排除)
2.重新编译Mysql （我是通过yum安装，后来又重新yum安装了freeradiusmysql

求各位朋友提点一下。
