opensips负载均衡最终脚本
0、安装
（1）安装rtpproxy
yum install rtpproxy 使用： rtpproxy -A 172.29.50.9 -F -l 192.168.1.100 -m 32004 -M 40000 -s udp:192.168.1.100:1111 -d DBUG LOG_LOCAL
解释：
rtpproxy启动
./rtpproxy -A 110.172.192.68 -l 0.0.0.0 -s udp:localhost:7890 -n tcp:localhost:7890 -F -d DBUG -m 50002 -M 50020 -d log_level:log_facility
参数解释如下：
-A 本机外网地址
-l 本机内网侦听地址
-s 本机侦听opensips通知端口
-n 超时通知接收端口
-F 不检查是否为超级用户模式
-d 调试消息输出级别
-m rtp最小端口
-M rtp最大端口
-d log_level为日志级别，值如下
DBUG INFO WARN ERR CRIT
log_facility为日志输出到哪，利用的系统日志
{"LOG_AUTH", LOG_AUTH},

（2）安装mediaproxy
wget http://download.ag-projects.com/MediaProxy/mediaproxy-2.6.1.tar.gz tar -xzvf mediaproxy-2.6.1.tar.gz ./setup.py install 开启： iptables -I INPUT -p udp --dport 5060 -j ACCEPT media-dispatcher start media-relay start #在启动的时候一定要观察/var/log/messages
具体配置参考：
