PPTP + FreeRADIUS + MySQL 安装与配置

FreeRADIUS 是实现 RADIUS 协议的开源软件,而 RADIUS 主要用来实现认证(Authentication)、授权(Authorization)以及计费(Accounting)功能。本文内容在Centos 5.7 32bit下测试成功。

一,VPN服务器安装配置

# 安装编译环境

yum install -y wget gcc gcc-c++ make

# 安装ppp

yum install -y ppp

# 安装PPTP VPN

wget http://hello-linux.googlecode.com/files/pptpd_with_freeradius_plugins.sh
chmod +x pptpd_with_freeradius_plugins.sh
./pptpd_with_freeradius_plugins.sh

注意:此PPTP VPN脚本已经加入了FreeRADIUS插件,不能脱离FreeRADIUS独立使用。如果你只想安装PPTP VPN的话,请不要使用此脚本。
此时如果提示“错误691:由于域上的用户名和/或密码无效而拒绝访问”,请不要担心,这是正常的。

二,FreeRADIUS 客户端安装与配置

# freeradius-client安装

cd /root
wget ftp://ftp.freeradius.org/pub/freeradius/freeradius-client-1.1.6.tar.gz
tar zxvf freeradius-client-1.1.6.tar.gz
cd freeradius-client-1.1.6
./configure && make && make install

# freeradius-client配置

vi /usr/local/etc/radiusclient/radiusclient.conf

找到 authserver 和 acctserver 将值改为 localhost
将 radius_deadtime 0 和 bindaddr * 将这两项注释掉(或者通过以下命令来注释之)

sed -i ‘s/radius_deadtime/\#radius_deadtime/g‘ /usr/local/etc/radiusclient/radiusclient.conf
sed -i ‘s/bindaddr/\#bindaddr/g‘ /usr/local/etc/radiusclient/radiusclient.conf

# 指定FreeRADIUS Server地址,并设置通信密码

cat >>/usr/local/etc/radiusclient/servers<<EOF
localhost   testing123
EOF

注意:这里的通信密码不建议更改!经本人测试,更改后使用不正常。

# 增加字典。这一步很重要!否则windows客户端无法连接服务器

wget -c http://hello-linux.googlecode.com/files/dictionary.microsoft
mv ./dictionary.microsoft /usr/local/etc/radiusclient/
cat >>/usr/local/etc/radiusclient/dictionary<<EOF
INCLUDE /usr/local/etc/radiusclient/dictionary.sip
INCLUDE /usr/local/etc/radiusclient/dictionary.ascend
INCLUDE /usr/local/etc/radiusclient/dictionary.merit
INCLUDE /usr/local/etc/radiusclient/dictionary.compat
INCLUDE /usr/local/etc/radiusclient/dictionary.microsoft
EOF

三,FreeRADIUS 服务端安装与配置

# 安装 mysql

yum install mysql mysql-devel mysql-server
service mysqld start
chkconfig mysqld on
mysqladmin -uroot -p password 新密码
# 此时会让你输入原密码,一般 mysql 安装好以后的初始密码为空,因此直接回车即可
# 如果使用非上述方式安装了MySQL(比如lnmp一键安装包里自带的mysql),请执行以下两条语句
ln -s /usr/local/mysql/bin/mysql /usr/bin
ln -s /usr/local/mysql/bin/mysqladmin /usr/bin

# 安装 freeradius-server

wget ftp://ftp.freeradius.org/pub/freeradius/freeradius-server-2.1.12.tar.gz
tar zxf freeradius-server-2.1.12.tar.gz
cd freeradius-server-2.1.12
./configure | grep mysql
# grep 这步操作主要是查看mysql的几个参数是不是都是yes,如果不是,需要检查下mysql安装.
make && make install

# 基本文本数据的本地测试

vi /usr/local/etc/raddb/users
# 找到 steve Cleartext-Password := “testing” , 取消该段的相关注释
steve   Cleartext-Password := "testing"
        Service-Type = Framed-User,
        Framed-Protocol = PPP,
        Framed-IP-Address = 172.16.3.33,
        Framed-IP-Netmask = 255.255.255.0,
        Framed-Routing = Broadcast-Listen,
        Framed-Filter-Id = "std.ppp",
        Framed-MTU = 1500,
        Framed-Compression = Van-Jacobsen-TCP-IP
radiusd -X
# 进入debug日志输出模式
# 如果有出现
Listening on authentication address * port 1812
Listening on accounting address * port 1813
Listening on command file /usr/local/var/run/radiusd/radiusd.sock
Listening on proxy address * port 1814
Ready to process requests.
# 这些字样说明正常启动成功了
 
# 重新打开一个窗口,执行下面这条命令
radtest steve testing localhost 1812 testing123 # 用户名steve密码testing , 连接密钥testing123
# 出现 rad_recv: Access-Accept packet 字样说明验证成功

# freeradius 和 mysql 集成

mysqladmin -u root -p create radius
mysql -u root -p radius < /usr/local/etc/raddb/sql/mysql/schema.sql
mysql -u root -p radius < /usr/local/etc/raddb/sql/mysql/nas.sql
mysql -u root -p radius < /usr/local/etc/raddb/sql/mysql/ippool.sql
mysql -u root -p radius < /usr/local/etc/raddb/sql/mysql/wimax.sql
mysql -u root -p
mysql> GRANT SELECT ON radius.* TO ‘radius‘@‘localhost‘ IDENTIFIED BY ‘radpass‘;
mysql> GRANT ALL on radius.radacct TO ‘radius‘@‘localhost‘;
mysql> GRANT ALL on radius.radpostauth TO ‘radius‘@‘localhost‘;
mysql> use radius;
 
# 加入组信息,本例中的组名为user
mysql> insert into radgroupreply (groupname,attribute,op,value) values (‘user‘,‘Auth-Type‘,‘:=‘,‘Local‘);
mysql> insert into radgroupreply (groupname,attribute,op,value) values (‘user‘,‘Service-Type‘,‘=‘,‘Framed-User‘);
mysql> insert into radgroupreply (groupname,attribute,op,value) values (‘user‘,‘Framed-IP-Netmask‘,‘:=‘,‘255.255.255.0‘);
 
# 加入用户信息
mysql> INSERT INTO radcheck (UserName, Attribute, Value) VALUES (‘sqltest‘, ‘Password‘, ‘testpwd‘);
 
# 用户加到组里
mysql> insert into radusergroup(username,groupname) values(‘sqltest‘,‘user‘);
 
# 限制账户同时登陆次数
mysql> INSERT INTO radgroupcheck (GroupName, Attribute, op, Value) values("user", "Simultaneous-Use", ":=", "1");
vi /usr/local/etc/raddb/sql.conf
# 设定数据库类型,帐号,密码,数据库,根据实际情况修改
# 找到 readclients = yes 取消前面的注释,取消该注释主要是启用nas表查询,clients.conf就可以不需要了
 
vi /usr/local/etc/raddb/radiusd.conf
# 查找$INCLUDE sql.conf(第700行),去掉#号
 
vi /usr/local/etc/raddb/sites-enabled/default
# 找到authorize {}模块,注释掉files(170行),去掉sql前的#号(177行)
# 找到accounting {}模块,注释掉radutmp(396行),去掉sql前面的#号(406行)
# 找到session {}模块,注释掉radutmp(450行),去掉sql前面的#号(454行)
# 找到post-auth {}模块,去掉sql前的#号(475行),去掉sql前的#号(563行)
 
vi /usr/local/etc/raddb/sites-enabled/inner-tunnel
# 找到authorize {}模块,注释掉files(124行),去掉sql前的#号(131行)
# 找到session {}模块,注释掉radutmp(251行),去掉sql前面的#号(255行)
# 找到post-auth {}模块,去掉sql前的#号(277行),去掉sql前的#号(301行)

# 正常启动 FreeRADIUS 并加入开机自启动项

cd /root
wget http://hello-linux.googlecode.com/files/radiusd
mv radiusd /etc/init.d/
chmod +x /etc/init.d/radiusd
vi /etc/init.d/radiusd
# 找到prefix=/usr/local/radius(第25行),将其改为prefix=/usr/local
/etc/init.d/radiusd start
 
vi /etc/rc.local
# 在最后一行插入/etc/init.d/radiusd start

# 最终测试

# 用刚才插入数据库的用户名和密码来检验
radtest sqltest testpwd localhost 1812 testing123
# 出现 rad_recv: Access-Accept packet 字样说明安装已经成功

至此,安装已完成。

可能出现的问题:

/usr/local/etc/raddb/sites-enabled/inner-tunnel[118]: Failed to find module “sql”.
/usr/local/etc/raddb/sites-enabled/inner-tunnel[34]: Errors parsing authorize section.
 
# 在系统里找下是否有rlm_sql_mysql.so这个文件,如果没有,那么依次执行以下命令:
cd /root/freeradius-server-2.1.12/src/modules/rlm_sql/drivers/rlm_sql_mysql
./configure --with-mysql-dir=/var/lib/mysql --with-mysql-lib-dir=/var/lib/mysql/lib --with-mysql-include-dir=/var/lib/mysql/include
make && make install
cd /usr/local/lib
cp rlm_sql_mysql.* /root/freeradius-server-2.1.12/src/modules/rlm_sql/drivers/rlm_sql_mysql/
radiusd -X
radiusd: error while loading shared libraries:libfreeradius-radius-2.1.12.so: cannot open shared object file: No such file or directory
 
执行以下命令即可:
ldconfig
