CentOS 5.4 pptp + freeradius2 +mysql +daloradius 完美整合（图文并茂）

只写操作的过程，其它没有相应的说明！！

CentOS 5.4下配置pptpd服务器已经在其它篇章中有描述，这里为文章的链接入口<< CentOS release 5.4 (Final) 配置PPTP VPN服务器（初步）>>

！！本文也是在此基础上做的改变，请先参照上述文章，完成PPTP VPN服务器的构建，再做如下步骤！！

一、安装相关配置包

1、安装httpd、mysql及php相关包

[root@localhost ~]# yum -y install httpd httpd-devel mysql mysql-server mysql-devel[root@localhost ~]# yum -y install php php-devel php-mysql php-common php-gd php-mbstring php-mcry

2、配置httpd服务：

[root@localhost ~]# netstat -ant |grep 80[root@localhost ~]# /etc/init.d/httpd startStarting httpd:                                            [  OK  ][root@localhost ~]# vi /etc/sysconfig/iptables[root@localhost ~]# grep 80 /etc/sysconfig/iptables-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 80 -j ACCEPT  #增加此行[root@localhost ~]# /etc/init.d/iptables restartFlushing firewall rules:                                   [  OK  ]Setting chains to policy ACCEPT: filter nat                [  OK  ]Unloading iptables modules:                                [  OK  ]Applying iptables firewall rules:                          [  OK  ]Loading additional iptables modules: ip_conntrack_netbios_n[  OK  ][root@localhost ~]# chkconfig httpd --listhttpd           0:off   1:off   2:off   3:off   4:off   5:off   6:off[root@localhost ~]# chkconfig httpd on  #设置httpd自动启动[root@localhost ~]# chkconfig httpd --listhttpd           0:off   1:off   2:on    3:on    4:on    5:on    6:off[root@localhost ~]# netstat -ant |grep 80tcp        0      0 :::80                       :::*                        LISTEN

3、启动mysql数据库：

[root@localhost ~]# /etc/init.d/mysqld startInitializing MySQL database:  Installing MySQL system tables...OKFilling help tables...OKTo start mysqld at boot time you have to copysupport-files/mysql.server to the right place for your systemPLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !To do so, start the server, then issue the following commands:/usr/bin/mysqladmin -u root password 'new-password'/usr/bin/mysqladmin -u root -h localhost.localdomain password 'new-password'Alternatively you can run:/usr/bin/mysql_secure_installationSee the manual for more instructions.You can start the MySQL daemon with:cd /usr ; /usr/bin/mysqld_safe &You can test the MySQL daemon with mysql-test-run.plcd mysql-test ; perl mysql-test-run.plPlease report any problems with the /usr/bin/mysqlbug script!The latest information about MySQL is available on the web athttp://www.mysql.comSupport MySQL by buying support/licenses at http://shop.mysql.com                                                           [  OK  ]Starting mysqld:                                           [  OK  ]

4、设置数据库密码;

[root@localhost ~]# mysqladmin -u root password 'leekwen'

5、安装Freeradius2相关包

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

6、启动radius进程，调试模式：

[root@localhost ~]# radiusd -XFreeRADIUS Version 2.1.12, for host i386-redhat-linux-gnu, built on Jan  9 2013 at 05:02:57Copyright (C) 1999-2009 The FreeRADIUS server project and contributors. ... adding new socket proxy address * port 51738Listening on authentication address * port 1812Listening on accounting address * port 1813Listening on command file /var/run/radiusd/radiusd.sockListening on authentication address 127.0.0.1 port 18120 as server inner-tunnelListening on proxy address * port 1814Ready to process requests.

7、开启另外一个终端进行测试，如图：

8、如果结果与上图不同，请临时关闭防火墙后，临时关闭防火墙命令如下：

[root@localhost ~]# iptables -F

重新运行测试命令：

[root@localhost ~]# radtest steve testing localhost 1812 testing123

##############
#  ！！error ！！  #
##############
Failed binding to authentication address * port 1812: Address already in use
/etc/raddb/radiusd.conf[240]: Error binding to port for 0.0.0.0 port 1812

请先用 lsof 命令查看，再用 killall -9 radiusd命令结束后，重新开启服务后，在进行测试！

二、下载ppp源码文件，集成ppp client:

1、下载源码：

[root@localhost ~]# wget ftp://ftp.samba.org/pub/ppp/ppp-2.4.4.tar.gz--2013-07-01 18:33:36--  ftp://ftp.samba.org/pub/ppp/ppp-2.4.4.tar.gz           => `ppp-2.4.4.tar.gz'Resolving ftp.samba.org... 216.83.154.106, 2001:470:1f05:1a07::1Connecting to ftp.samba.org|216.83.154.106|:21... connected.Logging in as anonymous ... Logged in!==> SYST ... done.    ==> PWD ... done.==> TYPE I ... done.  ==> CWD /pub/ppp ... done.==> SIZE ppp-2.4.4.tar.gz ... 688763==> PASV ... done.    ==> RETR ppp-2.4.4.tar.gz ... done.Length: 688763 (673K)100%[===========================================>] 688,763      135K/s   in 5.3s2013-07-01 18:33:45 (127 KB/s) - `ppp-2.4.4.tar.gz' saved [688763]

2、解压并做相关配置

[root@localhost ~]# tar zxf ppp-2.4.4.tar.gz[root@localhost ~]# cp -R ppp-2.4.4/pppd/plugins/radius/etc/ /etc/radiusclient[root@localhost ~]# cp /etc/radiusclient/radiusclient.conf /etc/radiusclient/radiusclient.conf.bak[root@localhost ~]# vi /etc/radiusclient/radiusclient.conf行号                修改前的配置文件                                修改后的配置文件25   issue         /usr/local/etc/radiusclient/issue      修改为：issue        /etc/radiusclient/issue46   servers      /usr/local/etc/radiusclient/servers     修改为：servers     /etc/radiusclient/servers50   dictionary  /usr/local/etc/radiusclient/dictionary   修改为：dictionary /etc/radiusclient/dictionary61   mapfile    /usr/local/etc/radiusclient/port-id-map   修改为：mapfile   /etc/radiusclient/port-id-map

说明：修改相关配置文件的路径，确保radiusclient.conf这个文件中radiusclient相关的路径都是“/etc/radiusclient”开头的.

3、配置字典文件：

[root@localhost ~]# ls -l /etc/radiusclient/dictionary*-rw-r--r-- 1 root root  7656 Jul  1 18:34 /etc/radiusclient/dictionary-rw-r--r-- 1 root root 12295 Jul  1 18:34 /etc/radiusclient/dictionary.ascend-rw-r--r-- 1 root root  1395 Jul  1 18:34 /etc/radiusclient/dictionary.compat-rw-r--r-- 1 root root   599 Jul  1 18:34 /etc/radiusclient/dictionary.merit-rw-r--r-- 1 root root  2649 Jul  1 18:34 /etc/radiusclient/dictionary.microsoft[root@localhost ~]# vi /etc/radiusclient/dictionary行号          文件内容253  INCLUDE /etc/radiusclient/dictionary.microsoft254  INCLUDE /etc/radiusclient/dictionary.merit    #增加此行255  INCLUDE /etc/radiusclient/dictionary.ascend   #增加此行256  INCLUDE /etc/radiusclient/dictionary.compat   #增加此行

4、在pptpd服务中添加freeradius插件：

[root@localhost ~]# vi /etc/ppp/options.pptpd行号          文件内容128  # put plugins here129  # (putting them higher up may cause them to sent messages to the pty)130  plugin /usr/lib/pppd/2.4.4/radius.so    #增加此行131  plugin /usr/lib/pppd/2.4.4/radattr.so    #增加此行132  radius-config-file /etc/radiusclient/radiusclient.conf    #增加此行[root@localhost ~]# tail -n 3 /etc/ppp/options.pptpdplugin /usr/lib/pppd/2.4.4/radius.soplugin /usr/lib/pppd/2.4.4/radattr.soradius-config-file /etc/radiusclient/radiusclient.conf

三、建立radius数据库及导入相应的数据库表：

可采用命令或使用Navicat for MySQL工具来完成：
1、radius中提供了mysql的导入文件：

[root@localhost ~]# ls /etc/raddb/sql/mysql/*.sql -l-rw-r----- 1 root radiusd  661 Jan  9 02:04 /etc/raddb/sql/mysql/admin.sql-rw-r----- 1 root radiusd  452 Jan  9 02:04 /etc/raddb/sql/mysql/cui.sql-rw-r----- 1 root radiusd  761 Jan  9 02:04 /etc/raddb/sql/mysql/ippool.sql-rw-r----- 1 root radiusd  399 Jan  9 02:04 /etc/raddb/sql/mysql/nas.sql-rw-r----- 1 root radiusd 4318 Jan  9 02:04 /etc/raddb/sql/mysql/schema.sql-rw-r----- 1 root radiusd  407 Jan  9 02:04 /etc/raddb/sql/mysql/wimax.sql

2、这里采用了命令方式，首先建立radius数据库：
为了方便以后使用Navicat for MySQL工具管理Mysql数据库，所以做了权限等方便的修改：

3、具体操作可复制代码：

[root@localhost ~]# mysql -uroot -pEnter password:Welcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 4Server version: 5.0.95 Source distributionCopyright (c) 2000, 2011, Oracle and/or its affiliates.

4、防火墙中关于数据库相关的设置：

[root@localhost ~]# grep 3306 /etc/sysconfig/iptables[root@localhost ~]# vi /etc/sysconfig/iptables[root@localhost ~]# /etc/init.d/iptables restartFlushing firewall rules:                                   [  OK  ]Setting chains to policy ACCEPT: filter nat                [  OK  ]Unloading iptables modules:                                [  OK  ]Applying iptables firewall rules:                          [  OK  ]Loading additional iptables modules: ip_conntrack_netbios_n[  OK  ][root@localhost ~]# grep 3306 /etc/sysconfig/iptables-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 3306 -j ACCEPT

四、修改radius的相关配置文件：

[root@localhost ~]# cp /etc/raddb/radiusd.conf /etc/raddb/radiusd.conf.bak[root@localhost ~]# vi /etc/raddb/radiusd.conf行号 ｜      修改后配置                ｜           未修改的配置700  ｜ $INCLUDE sql.conf              ｜ #  $INCLUDE sql.conf <------去掉注释#712  ｜ $INCLUDE sql/mysql/counter.conf｜ #  $INCLUDE sql/mysql/counter.conf  <------去掉注释#[root@localhost ~]# cp /etc/raddb/sql.conf /etc/raddb/sql.conf.bak[root@localhost ~]# vi /etc/raddb/sql.conf行号 ｜     修改后配置           ｜     未修改的配置38   ｜   login = "root"         ｜   login = "radius"   <------修改连接mysql的用户名39   ｜   password = "leekwen"   ｜  password = "radpass"<------修改连接mysql的密码100  ｜   readclients = yes      ｜ #readclients = yes   <------去掉注释#

说明：如果在运行radiusd -X 时会加载配置文件；
如果看到加载的配置文件时，出现下面的错误:

!!! Error !!!

Duplicate virtual server "inner-tunnel" in file /etc/raddb/sites-enabled/inner-tunnel:11 
and file /etc/raddb/sites-enabled/inner-tunnel.bak:11
请将/etc/raddb/sites-enabled/inner-tunnel.bak 与 /etc/raddb/sites-enabled/default.bak全部删除，
这也是为什么下面在编辑前没有备份这两个文件的原因：

[root@localhost ~]# vi /etc/raddb/sites-enabled/default行号  ｜       修改后配置                    ｜               未修改的配置170    #       files                         ｜          files  <------增加注释#177            sql                           ｜  #       sql    <------去掉注释#372    #       files                         ｜          files  <------增加注释#406            sql                           ｜  #       sql  <------去掉注释#454            sql                           ｜  #       sql  <------去掉注释#475            sql                           ｜  #       sql  <------去掉注释#[root@localhost ~]# vi /etc/raddb/sites-enabled/inner-tunnel行号  ｜      修改后配置                     ｜           未修改的配置124   #       files                          ｜           files <------增加注释#131           sql                            ｜   #       sql  <------去掉注释#255           sql                            ｜   #       sql  <------去掉注释#277           sql                            ｜   #       sql  <------去掉注释#

2、启动radiusd服务，并在数据库总插入测试账号，并查看测试结果！

3、测试通过后，修改默认密钥密码：

[root@localhost ~]# cp /etc/raddb/clients.conf /etc/raddb/clients.conf.bak[root@localhost ~]# vi /etc/raddb/clients.conf行号  ｜      修改后配置                  ｜           未修改的配置101       secret          = leekwen       ｜        secret          = testing123

4、重新启动相关服务后，进行数据库用户测试！

5、此测试通过后，进行客户端的拨号连接，并在服务端查看客户端的拨号日志：

6、到此，已经完成了，pptpd + freeradius2 + mysql 三者之间的整合，后续章节中将增加前台配置页面daloradius，用它提供一个友好的配置界面！！
