SER 0.9.4+Freeradius安裝(源程式碼安裝)配置過程

環境： centos4.2: 相當於redhat el4或fc4. SER0.9.4, radiusclient-ng-0.5.2(ser的radius客戶端) freeradius1.0.1(centos自帶) mysql4.1.12(centos自帶)

目標： 1).SER通過mysql資料庫對sip客戶進行認證. 2).SER通過radius對sip客戶進行計費.

安裝： 1.安裝ser伺服器 ==>到[url]www.iptel.org/ser[/url]下載ser-0.9.4_src.tar.gz. ==>到[url]http://developer.berlios.de/projects/radiusclient-ng[/url]下載 radiusclient-ng-0.5.2.tar.gz. ==>編譯/安裝radiusclient-ng-0.5.2.tar.gz. ==>tar zxvf ser-0.9.4_src.tar.gz解壓文件. ==>進入解壓後目錄的modules/acc目錄下, 修改Makefile使ser啟用sql 計費和radius計費支援. 去掉#DEFS+=-DSQL_ACC行前面的"#"號 去掉#DEFS+=-DRAD_ACC #include ../../Makefile.radius兩行前面的"#"號 ==>進入ser主目錄, 執行make編譯ser, 執行make install安裝ser.

2.配置ser的mysql支援 ==>進入ser源程式的modules/mysql目錄. ==>執行make編譯ser的mysql支援模組. ==>執行cp mysql.so /usr/local/lib/ser/modules把生成的動態鏈接 庫拷貝到ser的模組目錄中. ==>執行/usr/local/sbin/ser_mysql.sh create生成mysql資料庫結構 需要輸入mysql的root用戶的密碼, 執行成功後會在創建一個名叫ser 的mysql資料庫.

3.配置ser的radius計費支援 ==>到[url]http://mirror.centos.org/centos/4.2/os/i386/CentOS/RPMS/[/url] 下載radius伺服器的支援(5個文件), 如果安裝centos4.2時選擇的是 完全安裝, 則不需要這一步. 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 ==>執行rpm -ivh freeradius-1.0.1-3.RHEL4.i386.rpm, 根據提示信 息安裝相應的freeradius支援庫, 再安裝這個包. ==>cd /usr/share/doc/freeradius-1.0.1目錄 執行：mysql -uroot -ppassw0rd radius < db_mysql.sql安裝free radius的mysql資料庫, 執行成功後會在mysql中創建一個名為radius 的資料庫 ==>進入/etc/raddb目錄, 修改radiusd.conf配置文件. 去掉#passwd = /etc/passwd行前面的"#"號 去掉#group = /etc/group行前面的"#"號 去掉authorize {…}中#sql前的"#"號 去掉accounting {…}中#sql前的"#"號 ==>進入/etc/raddb目錄, 修改sql.conf配置文件. 修改password = "rootpass"這行為password = "passw0rd"(即root 用戶的密碼) ==>進入/etc/raddb目錄, 修改users配置文件. 注釋掉： DEFAULT Auth-Type = System Fall-Through = 1 這兩行, 目的是禁止radius用本地帳號對用戶進行驗證.

4.配置ser伺服器的sql計費/radius計費支援 ==>進入/usr/local/etc/ser目錄, 根據"ser源程式安裝目錄/modules/ acc目錄中的README文件配置ser的sql計費和radius計費支援, 具體 配置參數參考/usr/local/etc/ser目錄

5.啟動各個伺服器, 測試 ==>radius -X以debug模式啟動freeradius伺服器 ==>ser start啟動ser伺服器 ==>使用serctl工具添加分機, 格式serctl add user secret email ==>執行serctl add 1111 1111 1111@localhost添加一個分機, 需要輸 入mysql用戶ser的密碼heslo, 並且export SIP_DOMAIN=localhost這 個環境變數 ==>執行serctl add 2222 2222 2222@localhost添加一個分機, 需要輸 入mysql用戶ser的密碼heslo, 並且export SIP_DOMAIN=localhost這 個環境變數

==>在另一個窗口中執行serctl moni命令, 觀察ser的調試輸出, 開始 用兩個分機撥號, 接通後, 觀察radius的調試窗口, 發現有資訊輸出 通話結束, 查看ser資料庫中的acc表和radius資料庫中的radacct表, 會發現它們各自都多了三行, 分別記錄sip的INVITE/ACK/BYE方法的 時間, 這樣, 就可以實現ser的計費功能了.

6.ser的web管理方式

關於SERWEB的內容本文不做過多涉及，將另開新貼討論，下面的兩個工具我目前都在用，而且正在計劃改寫，包括漢化、整合、做Extmail的語音郵箱插件、移植到Postgresql等。 以下資訊從voip-info網站得到 ==>serweb可以查看帳戶等資訊, 但不能修改. ==>ser-sip-prov-0_1.tar.gz可以添加帳戶. 附錄： 1.注意, 有時候SER不能正常啟動, 需要使用命令: ldconfig 使系統註冊SER所依賴的某些庫. 2.SER配置文件(/usr/local/etc/ser.cfg): # # $Id: ser.cfg,v 1.25.2.1 2005/02/18 14:30:44 andrei Exp $ # # simple quick-start config script #
