$ mysql -uroot -p
> CREATE DATABASE radius;
> use radius;
> source /etc/freeradius/sql/mysql/admin.sql;
admin.sql 里面可以修改 raidius 的账号密码,但也需要在 raddb/sql.conf 中修改
> source /etc/freeradius/sql/mysql/schema.sql;
> source /etc/freeradius/sql/mysql/ippool.sql;
> source /etc/freeradius/sql/mysql/schema.sql;
> source /etc/freeradius/sql/mysql/wimax.sql;
> source /etc/freeradius/sql/mysql/cui.sql;
> source /etc/freeradius/sql/mysql/nas.sql;

配置 freeradius

配置文件在/usr/local/etc/raddb

1
# cd /usr/local/etc/raddb

仔细阅读 radiusd.conf

打开 radius 的 sql 模块

1
# ln -s ../mods-available/sql

将数据库配置变为 mysql,并且取消用户名密码端口 ip 这一组注释

1
# radius -X

检查启动信息,如果出现

1
rlm_sql_mysql: Connected to database 'radius' on Localhost via UNIX socket, server version 5.5.54-0ubuntu0.14.04.1, protocol version 10
