    部分内容转自VOIPFC,原文使用的SER版本不是最新的了,我在自己实践的基础上将对文档进行一下完善。

    -----------------------------------------
     
    文档正文
    SER 0.9.4+Freeradius安装(源代码安装)配置过程
     
    环境:
    centos4.2: 相当于redhat el4或fc4.
    SER0.9.4, radiusclient-ng-0.5.2(ser的radius客户端)
    freeradius1.0.1(centos自带)
    mysql4.1.12(centos自带)
     
    目标:
    1).SER通过mysql数据库对sip客户进行认证.
    2).SER通过radius对sip客户进行计费.
     
    安装:
    1.安装ser服务器
    ==>到[url]www.iptel.org/ser[/url]下载ser-0.9.4_src.tar.gz.
    ==>到[url]http://developer.berlios.de/projects/radiusclient-ng[/url]下载
    radiusclient-ng-0.5.2.tar.gz.
    ==>编译/安装radiusclient-ng-0.5.2.tar.gz.
    ==>tar zxvf ser-0.9.4_src.tar.gz解压文件.
    ==>进入解压后目录的modules/acc目录下, 修改Makefile使ser启用sql
    计费和radius计费支持.
    去掉#DEFS+=-DSQL_ACC行前面的"#"号
    去掉#DEFS+=-DRAD_ACC
    #include ../../Makefile.radius两行前面的"#"号
    ==>进入ser主目录, 执行make编译ser, 执行make install安装ser.

    2.配置ser的mysql支持
    ==>进入ser源程序的modules/mysql目录.
    ==>执行make编译ser的mysql支持模块.
    ==>执行cp mysql.so /usr/local/lib/ser/modules把生成的动态链接
    库拷贝到ser的模块目录中.
    ==>执行/usr/local/sbin/ser_mysql.sh create生成mysql数据库结构
    需要输入mysql的root用户的密码, 执行成功后会在创建一个名叫ser
    的mysql数据库.

    3.配置ser的radius计费支持
    ==>到[url]http://mirror.centos.org/centos/4.2/os/i386/CentOS/RPMS/[/url]
    下载radius服务器的支持(5个文件), 如果安装centos4.2时选择的是
    完全安装, 则不需要这一步.
    freeradius-1.0.1-3.RHEL4.i386.rpm
    freeradius-mysql-1.0.1-3.RHEL4.i386.rpm
    libtool-libs-1.5.6-4.EL4.1.i386.rpm
    net-snmp-5.1.2-11.EL4.6.i386.rpm
    net-snmp-utils-5.1.2-11.EL4.6.i386.rpm
    ==>执行rpm -ivh freeradius-1.0.1-3.RHEL4.i386.rpm, 根据提示信
    息安装相应的freeradius支持库, 再安装这个包.
    ==>cd /usr/share/doc/freeradius-1.0.1目录
    执行:mysql -uroot -ppassw0rd radius < db_mysql.sql安装free
    radius的mysql数据库, 执行成功后会在mysql中创建一个名为radius
    的数据库
    ==>进入/etc/raddb目录, 修改radiusd.conf配置文件.
    去掉#passwd = /etc/passwd行前面的"#"号
    去掉#group = /etc/group行前面的"#"号
    去掉authorize {...}中#sql前的"#"号
    去掉accounting {...}中#sql前的"#"号
    ==>进入/etc/raddb目录, 修改sql.conf配置文件.
    修改password = "rootpass"这行为password = "passw0rd"(即root
    用户的密码)
    ==>进入/etc/raddb目录, 修改users配置文件.
    注释掉:
    DEFAULT Auth-Type = System
    Fall-Through = 1
    这两行, 目的是禁止radius用本地账号对用户进行验证.

    4.配置ser服务器的sql计费/radius计费支持
    ==>进入/usr/local/etc/ser目录, 根据"ser源程序安装目录/modules/
    acc目录中的README文件配置ser的sql计费和radius计费支持, 具体
    配置参数参考/usr/local/etc/ser目录

    5.启动各个服务器, 测试
    ==>radius -X以debug模式启动freeradius服务器
    ==>ser start启动ser服务器
    ==>使用serctl工具添加分机, 格式serctl add user secret email
    ==>执行serctl add 1111 1111 1111@localhost添加一个分机, 需要输
    入mysql用户ser的密码heslo, 并且export SIP_DOMAIN=localhost这
    个环境变量
    ==>执行serctl add 2222 2222 2222@localhost添加一个分机, 需要输
    入mysql用户ser的密码heslo, 并且export SIP_DOMAIN=localhost这
    个环境变量
    ==>在另一个窗口中执行serctl moni命令, 观察ser的调试输出, 开始
    用两个分机拨号, 接通后, 观察radius的调试窗口, 发现有信息输出
    通话结束, 查看ser数据库中的acc表和radius数据库中的radacct表,
    会发现它们各自都多了三行, 分别记录sip的INVITE/ACK/BYE方法的
    时间, 这样, 就可以实现ser的计费功能了.

    6.ser的web管理方式
    关于SERWEB的内容本文不做过多涉及,将另开新贴讨论,下面的两个工具我目前都在用,而且正在计划改写,包括汉化、整合、做Extmail的语音邮箱插件、移植到Postgresql等。
    以下信息从voip-info网站得到
    ==>serweb可以查看帐户等信息, 但不能修改.
    ==>ser-sip-prov-0_1.tar.gz可以添加帐户.

    附录:
    1.注意, 有时候SER不能正常启动, 需要使用命令:
    ldconfig 使系统注册SER所依赖的某些库.
