一、安装FreeRadius 和 MySQL

[root@radius ~]# yum install freeradius2 freeradius2-mysql freeradius2-utils

[root@radius ~]# yum install mysql mysql-server

二、开启MySQL和Radius服务

[root@radius ~]# service mysqld start

[root@radius ~]# radiusd –X

[root@radius ~]# service radiusd start

三、设置服务开机启动

[root@radius ~]# chkconfig mysqld --level 2345 on

[root@radius ~]# chkconfig radiusd --level 2345 on

四、做个简单的测试(可选操作)

①定义一个radius客户端ip

[root@radius ~]# vim /etc/raddb/clients.conf

删除原来的所有

配置示例：

client localhost {

ipaddr = 127.0.0.1

secret = testing123

require_message_authenticator = no

nastype = other

}

②定义一个用户和密码

[root@radius ~]# vim /etc/raddb/users

在第一行添加

配置示例：

testing Cleartext-Password := "password"

③以调试模式开启radius

[root@radius ~]# radiusd –X

状态如下：

Ready to process requests.

④测试服务是否正常

[root@radius ~]# radtest testing password localhost 0 testing123

返回结果(关键是返回Access-Accept)示例：

Sending Access-Request of id 152 to 127.0.0.1 port 1812

User-Name = "testing"

User-Password = "password"

NAS-IP-Address = 127.0.0.1

NAS-Port = 0

rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=152, length=20

五、创建一个MySQL数据库

[root@radius ~]# mysql -uroot –p

mysql> CREATE DATABASE radius;

mysql> GRANT ALL ON radius.* TO radius@localhost IDENTIFIED BY "radpass";

mysql> exit

[root@radius ~]# cd /etc/raddb/sql/mysql/

[root@radius mysql]# mysql -uroot -p radius < schema.sql

六、检查一下是否创建成功

[root@radius mysql]# mysql -uroot -p

mysql> show databases;

+--------------------+

| Database           |

+--------------------+

| information_schema |

| mysql              |

| radius             |

| test               |

+--------------------+

4 rows in set (0.03 sec)

mysql> use radius

mysql> show tables;

+------------------+

| Tables_in_radius |

+------------------+

| radacct          |

| radcheck         |

| radgroupcheck    |

| radgroupreply    |

| radpostauth      |

| radreply         |

| radusergroup     |

+------------------+

7 rows in set (0.00 sec)

七、配置FreeRadius使用SQL

[root@radius ~]# vim /etc/raddb/sql.conf

示例：

sql {

database = "mysql"

driver = "rlm_sql_${database}"

server = "localhost"

login = "radius"

password = "radpass"

radius_db = "radius"

acct_table1 = "radacct"

acct_table2 = "radacct"

postauth_table = "radpostauth"

authcheck_table = "radcheck"

authreply_table = "radreply"

groupcheck_table = "radgroupcheck"

groupreply_table = "radgroupreply"

usergroup_table = "radusergroup"

deletestalesessions = yes

sqltrace = no

sqltracefile = ${logdir}/sqltrace.sql

num_sql_socks = 5

connect_failure_retry_delay = 60

lifetime = 0

max_queries = 0

nas_table = "nas"

$INCLUDE sql/${database}/dialup.conf

}

[root@radius ~]# vim /etc/raddb/radiusd.conf

找到：

$INCLUDE sql.conf

去掉注释

以下区段需要注释掉files，去掉sql前的注释(没有则不需要)

[root@radius ~]# vim /etc/raddb/sites-available/default

authorize{}

accounting{}

session{}

post-auth{}

[root@radius ~]# vim /etc/raddb/sites-available/inner-tunnel

authorize {}

八、创建测试数据

①创建用户组[radgroupcheck]

②创建用户密码[radcheck]

③创建用户应答属性[radreply]

④创建组应答属性[radgroupreply]

下面是一个示例：

这个例子包含三个用户fredf，barney，dialrouter

fredf由NAS(网络接入服务器)动态分配ip

barney分配一个静态的ip

dialrouter表示的是一个典型的拨号路由

mysql> select * from radcheck;

+----+----------------+--------------------+------------------+------+

| id | UserName | Attribute | Value | Op |

+----+----------------+--------------------+------------------+------+

| 1 | fredf | Cleartext-Password | wilma | := |

| 2 | barney | Cleartext-Password | betty | := |

| 2 | dialrouter | Cleartext-Password | dialup | := |

+----+----------------+--------------------+------------------+------+

3 rows in set (0.01 sec)

mysql> select * from radreply;

+----+------------+-------------------+---------------------------------+------+

| id | UserName | Attribute | Value | Op |

+----+------------+-------------------+---------------------------------+------+

| 1 | barney | Framed-IP-Address | 1.2.3.4 | := |

| 2 | dialrouter | Framed-IP-Address | 2.3.4.1 | := |

| 3 | dialrouter | Framed-IP-Netmask | 255.255.255.255 | := |

| 4 | dialrouter | Framed-Routing | Broadcast-Listen | := |

| 5 | dialrouter | Framed-Route | 2.3.4.0 255.255.255.248 | := |

| 6 | dialrouter | Idle-Timeout | 900 | := |

+----+------------+-------------------+---------------------------------+------+

6 rows in set (0.01 sec)

mysql> select * from radgroupreply;

+----+-----------+--------------------+---------------------+------+

| id | GroupName | Attribute | Value | Op |

+----+-----------+--------------------+---------------------+------+

| 34 | dynamic | Framed-Compression | Van-Jacobsen-TCP-IP | := |

| 33 | dynamic | Framed-Protocol | PPP | := |

| 32 | dynamic | Service-Type | Framed-User | := |

| 35 | dynamic | Framed-MTU | 1500 | := |

| 37 | static | Framed-Protocol | PPP | := |

| 38 | static | Service-Type | Framed-User | := |

| 39 | static | Framed-Compression | Van-Jacobsen-TCP-IP | := |

| 41 | netdial | Service-Type | Framed-User | := |

| 42 | netdial | Framed-Protocol | PPP | := |

+----+-----------+--------------------+---------------------+------+

12 rows in set (0.01 sec)

创建测试用户

INSERT INTO radcheck (username,attribute,op,value) VALUES ('dialrouter','Cleartext-Password',':=','dialup');

INSERT INTO radreply (username,attribute,op,value) VALUES ('dialrouter','Framed-IP-Address',':=','2.3.4.1');

INSERT INTO radreply (username,attribute,op,value) VALUES ('dialrouter','Framed-IP-Netmask',':=','255.255.255.255');

INSERT INTO radreply (username,attribute,op,value) VALUES ('dialrouter','Framed-Routing',':=','Broadcast-Listen');

INSERT INTO radreply (username,attribute,op,value) VALUES ('dialrouter','Framed-Route',':=','2.3.4.0 255.255.255.248');

INSERT INTO radreply (username,attribute,op,value) VALUES ('dialrouter','Idle-Timeout',':=','900');

INSERT INTO radgroupreply (groupname,attribute,op,value) VALUES ('netdial','Service-Type',':=','Framed-User');

INSERT INTO radgroupreply (groupname,attribute,op,value) VALUES ('netdial','Framed-Protocol',':=','PPP');

九、测试是否创建成功

[root@radius ~]# radiusd -X

[root@radius ~]# radtest dialrouter dialup localhost 1812 testing123

Sending Access-Request of id 148 to 127.0.0.1 port 1812

User-Name = "dialrouter"

User-Password = "dialup"

NAS-IP-Address = 127.0.0.1

NAS-Port = 1812

rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=148, length=69

Framed-IP-Address = 2.3.4.1

Framed-IP-Netmask = 255.255.255.255

Framed-Routing = Broadcast-Listen

Framed-Route = "2.3.4.0 255.255.255.248"

Idle-Timeout = 900

十、配置RouteOS 使用radius认证

[root@radius ~]# vim /etc/raddb/clients.conf

client RouterOS {

ipaddr = 192.168.137.50

secret = 111

shortname = RouterOS

nastype = other

}

RouteOS的配置如下：
