Kamailio Sip 会议服务搭建

Kamailio Sip 会议服务搭建

在搭建Kamailio服务之前，请确保你已经安装了必要的依赖，如SIP proxy库（libkamailio）、数据库（如MySQL）、以及必要的编译工具（如make和gcc）。以下是一个简化的Kamailio服务器搭建流程：

1. 安装数据库（如MySQL）和数据库驱动（如mysqlclient）。
2. 安装Kamailio SIP代理软件。
3. 配置Kamailio以连接数据库。
4. 启动Kamailio服务。

以下是在基于UbuntuServer系统上的示例安装过程：

安装UbuntuServer

配置 SSH(非必要)

注：使用root登录后不用输入 sudo

sudo passwd root							#配置root密码
Enter new UNIX password: 					 #输入密码
Retype new UNIX password: 				   	 #再次输入密码
passwd: password updated successfully		  #完成设置

编辑 /etc/ssh/sshd_config (非必要)

sudo nano /etc/ssh/sshd_config

找到 改成 PermitRootLogin yes (非必要)
ctrl+o 保存 回车
ctrl+x退出

reboot		#重启一下服务器

给Server换源

注：使用root登录后不用输入 sudo

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup	#备份源地址
sudo nano /etc/apt/sources.list					#编辑sources.list文件

替换文件中的源地址为新的源。例如，使用阿里云的源：

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
...

sudo apt update			#更新软件列表
sudo apt upgrade		#升级所有包

安装MySQL和数据库驱动

sudo apt-get install mysql-server mysql-client
sudo apt-get install libmysqlclient-dev

安装Kamailio SIP代理软件

sudo apt-get update
sudo apt-get install kamailio kamailio-mysql-modules

mysql 5.7 设置root远程访问

登录mysql root用户

mysql -u root -p

输入root密码登录

执行以下语句：

mysql> use mysql; 
mysql> GRANT ALL ON *.* TO root@'%' IDENTIFIED BY 'Zt33133...' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;
mysql> exit;

以上步骤可能在mysql低版本上可行，如果还不能连接，继续下面操作

退出mysql,执行以下命令

vim /etc/mysql/mysql.conf.d/mysqld.cnf

找到bind-address=127.0.0.1，这一行，将其注释掉，即可

reboot		#重启一下服务器

配置Kamailio以连接MySQL数据库

打开 /etc/kamailio/kamailio.cfg，添加下面几行（添加在最顶端即可）

#!define WITH_MYSQL
#!define WITH_AUTH
#!define WITH_USRLOCDB

打开 /etc/kamailio/kamctlrc，去掉SIP_DOMAIN前的注释，并且修改成自己的服务器地址192.168.15.16（根据自己服务器的实际情况来写），我的是SIP_DOMAIN=192.168.15.16。然后去掉DBENGINE=MYSQL前的注释语句，选定mysql数据库，其他的按照如下内容来修改：

# The Kamailio configuration file for the control tools.
# Here you can set variables used in the kamctl and kamdbctl setup
# scripts. Per default all variables here are commented out, the control tools
# will use their internal default values.

## your SIP domain
SIP_DOMAIN=192.168.15.16

## chrooted directory
# $CHROOT_DIR="/path/to/chrooted/directory"

## database type: MYSQL, PGSQL, ORACLE, DB_BERKELEY, or DBTEXT, by default none is loaded

# If you want to setup a database with kamdbctl, you must at least specify
# this parameter.
DBENGINE=MYSQL

## database host
DBHOST=localhost

## database name (for ORACLE this is TNS name)
DBNAME=kamailio

# database path used by dbtext or db_berkeley
# DB_PATH="/usr/local/etc/kamailio/dbtext"

## database read/write user
DBRWUSER=kamailio

## password for database read/write user
DBRWPW="kamailiorw"

## database read only user
# DBROUSER=kamailioro
DBROUSER=kamailioro

## password for database read only user
DBROPW=kamailioro

## database super user (for ORACLE this is 'scheme-creator' user)
DBROOTUSER="root"

# user name column
USERCOL="username"

# SQL definitions
# If you change this definitions here, then you must change them
# in db/schema/entities.xml too.
# FIXME

# DEFAULT_ALIASES_EXPIRES=$FOREVER
# DEFAULT_Q="1.0"
# DEFAULT_CALLID="Default-Call-ID"
# DEFAULT_CSEQ="13"

# DEFAULT_LOCATION_EXPIRES=$FOREVER

# Program to calculate a message-digest fingerprint
# MD5="md5sum"

# awk tool
# AWK="awk"

# If you use a system with a grep and egrep that is not 100% gnu grep compatible,
# e.g. solaris, install the gnu grep (ggrep) and specify this below.
#

# grep tool
# GREP="grep"

# egrep tool
# EGREP="egrep"

# sed tool
# SED="sed"

# tail tool
# LAST_LINE="tail -n 1"

# expr tool

# EXPR="expr"

# Describe what additional tables to install. Valid values for the variables
# below are yes/no/ask. With ask (default) it will interactively ask the user
# for an answer, while yes/no allow for automated, unassisted installs.
#

# If to install tables for the modules in the EXTRA_MODULES variable.
# INSTALL_EXTRA_TABLES=ask

# If to install presence related tables.

# INSTALL_PRESENCE_TABLES=ask

# Define what module tables should be installed.
# If you use the postgres database and want to change the installed tables, then you
# must also adjust the STANDARD_TABLES or EXTRA_TABLES variable accordingly in the
# kamdbctl.base script.

# kamailio standard modules
# STANDARD_MODULES="standard acc lcr domain group permissions registrar usrloc msilo
# alias_db uri_db speeddial avpops auth_db pdt dialog dispatcher
# dialplan"

# Kamailio extra modules
# EXTRA_MODULES="imc cpl siptrace domainpolicy carrierroute userblacklist htable purple"

## type of aliases used: DB - database aliases; UL - usrloc aliases
## - default: none
# ALIASES_TYPE="DB"

## control engine: FIFO or UNIXSOCK
## - default FIFO
# CTLENGINE="FIFO"

## path to FIFO file
# OSER_FIFO="FIFO"

## check ACL names; default on (1); off (0)
# VERIFY_ACL=1

## ACL names - if VERIFY_ACL is set, only the ACL names from below list
## are accepted
# ACL_GROUPS="local ld int voicemail free-pstn"

## verbose - debug purposes - default '0'
VERBOSE=1

## do (1) or don't (0) store plaintext passwords
## in the subscriber table - default '1'

# STORE_PLAINTEXT_PW=0

## PID file path - default is: /var/run/Kamailio.pid
# PID_FILE=/var/run/kamailio/kamailio.pid
PID_FILE=/var/run/kamailio/kamailio.pid

## Extra start options - default is: not set
# example: start kamailio with 64MB share memory: STARTOPTIONS="-m 64"
# STARTOPTIONS=

建立MySQL数据库

sudo kamdbctl create

添加用户

sudo kamctl add 10001 123456
sudo kamctl add 10002 123456

重新启动kamctl

sudo kamctl stop
sudo kamctl start

确保替换user, password, host, port, 和 database为你的数据库实际的连接信息。

使Kamailio服务开机自启

## 此方法应该是正确的，但是不知为何UbuntuServer下失效了
# 启动Kamailio服务
sudo systemctl start kamailio
# （可选）使Kamailio服务开机自启
sudo systemctl enable kamailio

创建一个sip.sh启动脚本赋予权限并且编辑sip.sh内容加入启动服务

sudo touch /sip.sh		#创建脚本
sudo chmod 777 /sip.sh	 #赋予权限
sudo nano /sip.sh		#编辑脚本
systemctl start kamailio	#编辑sip.sh填入这行
#然后ctrl+o保存
#然后ctrl+x退出

输入 crontab -e 命令编辑crontab文件。添加这一行内容

@reboot sleep 50 && /sip.sh		#在系统重启后，等待50秒后执行.
#然后ctrl+o保存
#然后ctrl+x退出

reboot #重启测试

注：使用root登录后不用输入 sudo
