信令服务器（opensips简介）

概述在众多的sip服务器中，主要有俩大类，一类侧重于媒体/业务服务器，比如freeswitch/asterisk，另一类侧重于代理/负载服务器，比如opensips/kamailio。今天我们对opensips做一个简单介绍。OpenSIPS 是用于语音、视频、IM、在线状态和任何其他SIP扩展的开源 SIP 代理服务器。OpenSIPS 是一种多功能、多用途的SIP信令服务器，运营商、电信或 ITSP 将其用于 Class4/5平台、中继、企业/虚拟 PBX 解决方案、会话边界控制器、应用服务器、前端负载等解决方案、IMS 平台、呼叫中心等等。OpenSIPS 被推荐用于任何类型的 SIP 场景/服务：高吞吐量 – 数万CPS，数百万个在线呼叫（参见官方测试）路由和集成的灵活性 – 用于实现自定义路由逻辑的路由脚本，多个接口 API（参见手册）有效的应用程序构建 – 超过 120 个模块提供功能，用于 SIP 处理、后端操作、集成、路由逻辑（请参阅模块列表）本章节主要介绍opensips的编译安装、配置启动的通用流程。开发环境Centos：CentOS release 6 (Final)或以上版本opensips：2.4.9GCC/C++：4.4.7编译安装依赖库yum install -y autoconf automake libtool gcc-c++ ncurses-devel make zlib-devel lynx flex bison mysql pcre python-devel openssl-devel mysql-devel安装hiredisgit clone https://github.com/redis/hiredis.git hiredis
cd hiredis
make install源码安装包：https://opensips.org/pub/opensips/2.4.9/opensips-2.4.9.tar.gz
wget https://opensips.org/pub/opensips/2.4.9/opensips-2.4.9.tar.gz
tar –zxvf opensips-2.4.9.tar.gz编译安装：方法1：cd opensips-2.4.9
make include_modules="cachedb_redis db_mysql dialplan python tls_mgm proto_tls proto_ws proto_wss " prefix="/usr/local/opensips" install方法2：cd opensips-2.4.9
make menuconfig
增加 cachedb_redis db_mysql dialplan python tls_mgm proto_tls proto_ws proto_wss 模块编译
修改安装目录为 /usr/local/opensips
保存退出menuconfig
make install目录结构默认安装路径为 /usr/local/opensips编译安装完成后，检查安装目录opensips
