kamailio,asteisk,realtime 实现负载均衡(集群)完整配置笔记
環境
負載均衡+數據庫服務器
Centos-5.4 + kamailio-3.1.4 + mysql-5.0.77-4.el5_6.6
IP:192.168.1.30
?
asterisk服務器1
Centos-5.4 + asterisk-1.8
IP:192.168.1.31
?
asterisk服務器2
Centos-5.4 + asterisk-1.8
IP:192.168.1.32
?
目的
?
1：假設一個簡易的asterisk 集群，通過realtime 技術，在集中的一個數據庫中管理所有集群節點的分機號和撥號規則
2：asterisk服務器1上分機號段為 8100-8199
asterisk服務器2上分機號段為 8200-8299
3: 實現同一臺asteisk服務器上分機互打
4：實現同一號段分機互打
5：實現不同號段分機互打（由kamailio服務器轉發）
?
配置
?
1：asterisk服務器1
[root@localhost asterisk]# cat /etc/asterisk/res_config_mysql.conf
[general]
dbhost = 192.168.1.30
dbname = asterisk
dbuser = root
dbpass = luckytuo@gmail.com
dbport = 3306
?
?
[root@localhost asterisk]# cat /etc/asterisk/extconfig.conf
[settings]
sipusers => mysql,general,ast_sipfriends ; edit by tolooney
sippeers => mysql,general,ast_sipfriends ; edit by tolooney
extensions => mysql,general,ast_extensions_01 ; edit by tolooney
?
?
[root@localhost asterisk]# cat /etc/asterisk/extensions.conf
[internal]
switch => Realtime/internal@extensions ; edit by tolooney
?
[root@localhost asterisk]# cat /etc/asterisk/sip.conf
[general]
context=internal
rtcachefriends=yes
disallow=all
allow=ulaw
allow=ilbc
?
2：asterisk服務器2
[root@localhost asterisk]# cat /etc/asterisk/res_config_mysql.conf
[general]
dbhost = 192.168.1.30
dbname = asterisk
dbuser = root
dbpass = luckytuo@gmail.com
dbport = 3306
?
?
[root@localhost asterisk]# cat /etc/asterisk/extconfig.conf
[settings]
sipusers => mysql,general,ast_sipfriends ; edit by tolooney
sippeers => mysql,general,ast_sipfriends ; edit by tolooney
extensions => mysql,general,ast_extensions_02 ; edit by tolooney
?
?
[root@localhost asterisk]# cat /etc/asterisk/extensions.conf
[internal]
switch => Realtime/internal@extensions ; edit by tolooney
?
[root@localhost asterisk]# cat /etc/asterisk/sip.conf
[general]
context=internal
rtcachefriends=yes
disallow=all
allow=ulaw
allow=ilbc
?
?
備注：分機號存放在ast_sipfriends表中，撥號規則分別存在ast_extensions_01，ast_extensions_02..表中
