can't find /etc/raddb/sql

[ICHIBA Sara]

hello there,

I'm trying to install freeradius on a centos 7 VM. So far I installed
mariadb-server 1:5.5.41-2.el7_0 ,  freeradius   3.0.4-6.el7 ,
freeradius-mysql      3.0.4-6.el7  and freeradius-utils     3.0.4-6.el7 .

I'm using yum to install these packages. But when I try to import the sql
schema i can't find it.

any ideas? What's wrong whith what I did??
