使用背景：存在 Freeswitch 等语音网关应用服务，期望实现负载均衡、前置处理的功能，类似于Web应用服务的Nginx的角色
市场调研，发现了几家颇受欢迎的开源产品：
- Kamailio
- OpenSIPS
- Asterisk
Kamailio和OpenSIPS由于其灵活性、高性能和强大的路由能力，在开源SIP服务器领域尤其受到欢迎。
基于以上背景，从头开始学习并了解Kamailio.
Kamailio 是什么？
Kamailio是一个：
- SIP Server，SIP服务器
- SIP Proxy Server，SIP代理服务器
- SIP Registrar Server，SIP注册服务器
- SIP Location Server，SIP地址查询服务器
- SIP Redirection Server，SIP重定向服务器
- SIP Application Server，SIP应用服务器
- SIP Loadbalance Server，SIP负载均衡服务器
- SIP WebSocket Server，SIP WebSocket服务器
- SIP SBC Server，SIP SBC服务器
Kamailio基于GPLv2+开源协议发布，主要处理SIP协议，当你发现你的需求要对SIP报文类似于插桩、修饰的时候，你就应该想到这类产品。
Kamailio 开源项目地址，拥有2.2K的 Star, 也是不错的成绩。
当然，了解Kamailio 这个SIP服务器的前提就是，你知道什么是SIP。
很贴心的，官方还给专门写了一篇文章，作为你了解Kamailio的背景知识。这篇文章我也有学习和整理。
官方也推荐了其他的SIP知识学习网站：
- siptutorial.net
- tutorialspoint.com
- voip-info.org
书籍：
- SIP Beyond VoIP
- Understanding the Session Initiation Protocol
- SIP Demystified
- Internet Communications Using SIP
认识它，从源码安装、使用开始 5.8.x
光看文章介绍，总是有点干巴巴，也有关于他的中文文档，但是看着四年多没有更新，讲的内容又很基础，我们直接就从英文文档入手吧，基础的是入门指南，想要了解更多当然要阅读CookBook-5.5.x，你还可以在这里找到其他版本的CookBook。
目前2024年最新版本是在 5.8.x，那么我们就跟着入门指南实践部署一个基于Debian(uBuntu下)单机版本源码构建Kamailio（Debian和Centos也有构建好的安装方式，可以自行选择）
- Kamailio 5.8.2
- MySQL 5.7(8.x不行，初始化语法不兼容)，提前准备好
- git指令
- 一个Linux服务器
获取源码
创建目录
mkdir -p ~/kamailio-5.8
cd ~/kamailio-5.8
git上分支从3.1-5.8/master开发版，可以自行选择，我这边检出5.8最新稳定版本
git clone --depth 1 --no-single-branch git://git.kamailio.org/kamailio kamailio
cd kamailio
git checkout -b 5.8 origin/5.8
配置项目
在kamailio文件夹下，src文件夹是我们需要关注的，后续的编译配置都在这个目录下
在src文件夹下，项目结构是这样的：
￥:~/kamailio-5.8/kamailio/src$ ls -l

在Makefile所在的项目根目录，初始化配置文件
make cfg
编译之后就会多出一些文件，这些也是在Makefile的脚本中可以有迹可循的
-rw-r--r-- 1 kama kama 16 Jun 20 13:28 librpath.lst # 指定库文件的路径
-rw-r--r-- 1 kama kama 6350 Jun 20 13:28 main.d # 帮助管理编译时的依赖关系
-rw-r--r-- 1 root root 479768 Jun 20 13:28 main.o # 编译后的二进制形式的目标文件
-rw-r--r-- 1 kama kama 966 Jun 14 11:20 makecfg.lst # 包含了编译Kamailio时需要的额外配置指令或变量定义
-rw-r--r-- 1 kama kama 1885 Jun 26 09:50 modules.lst # 依赖模块的初始化文件，这个如果存在就会删了重新生成
-rw-r--r-- 1 root root 3600 Jun 20 13:27 config.mak # 用来指导后续的编译步骤（通常通过执行make命令）如何基于你的配置需求来构建Kamailio
其中 modules.lst 主要负责引入和排除加载的镜像，是通常使用过程中需要修改的，比如增加数据库模块、缓存模块、http请求模块

modules= $(filter-out $(modules_noinc), $(addprefix modules/, $(include_modules) )) $(modules_noinc)
modules_configured:=1
可以直接打开文件进行编辑，或者使用命令的方式 make include_modules="app_lua db_mysql" exclude_modules="xxxxx" cfg
以上你如果选用了对应的模块，前提是你的环境已经安装了哦，比如已经安装了MySQL(我这边安装的是MySQL5.7)，已经安装了Lua(我这边安装的是Lua5.4,liblua5.4-dev)
编译并安装项目
make all编译
$:~/kamailio-5.8/kamailio/src$ sudo make all
make[2]: 'libsrdb2.so.1.0' is up to date.

make[1]: 'app_jsdt.so' is up to date.
....
make install 安装
$:~/kamailio-5.8/kamailio/src$ sudo make install
安装完成后:
所有配置文件将位于：/usr/local/etc/kamailio，核心配置文件位于：/usr/local/etc/kamailio/kamailio.cfg
可执行文件位于： /usr/local/sbin/
- kamailio - SIP 服务器脚本
- kamdbctl - 创建和管理数据库的脚本，比如你使用MySQL作为其存储时就需要使用到这个
- kamctl - 管理和控制SIP服务器的脚本
- kamcmd - CLI 可以与SIP服务器交互的命令行接口
已经安装的模块位于：/usr/local/lib/kamailio/modules/，如果引用还有报包不存在的，就需要看看这里确认，没有的话编译安装可能要重来
一些文档位于： /usr/local/share/doc/kamailio/,/usr/local/share/man/man5/,/usr/local/share/man/man8/
日志输出位于： /var/log/syslog，好像有点疑惑为什么不是和其他的一样是关于kamailio的命名，这个可以配置
配置日志输出
kamailio.cfg配置文件中，找到关于日志的配置行log_facility=LOG_LOCAL0，确定没有注释掉- 对于Unbuntu 22.04，找到
/etc/rsyslog.d/50-default.conf文件，对syslog的配置进行调整
...
#注释掉这一行
#*.*;auth,authpriv.none -/var/log/syslog
#新加
*.*;auth,authpriv.none,local0.none -/var/log/syslog #追加local0
#新加
if $syslogfacility-text=='local0' then -/var/log/kamailio.log #将local0 输出到 kamailio.log，路径可以自定义 /var/log/kamailio/kamailio.log
...
配置MySQL数据库存储
默认情况下，不会引入任何数据库存储，我们这边是因为需要做持久化(也是正常使用的需求)，前面modules已经引入 db_mysql的模块

后台启动服务
/usr/local/sbin/kamailio start
那么这个时候也有可能你配置文件里面写的有语法、引用等异常，你会看到ERROR: PID file /run/kamailio/kamailio.pid does not exist -- Kamailio start failed，还要去日志看错误信息，很麻烦怎么办呢？
校验下服务，能看到错误输出，如果没有错误，再用后台启动

直观地看到错误信息，上面这个错误就很明显了，服务端口已经起着了，或者和别的服务端口冲突了。一切正常的话没有ERROR的话，就是没有语法错误。
对于新手的我，改脚本直接上文件写的，有这个命令还是很好用的，能告诉我第几行有错误。
终止服务

通常kamailio启动会调起很多端口，stop有时候清不干净，我通常会使用这个命令
