Centos7 下安装freeswitch 1.9 +x264+odbc mysql

前期准备

yum install net-tools
关闭防火墙

//临时关闭
systemctl stop firewalld
//禁止开机启动
systemctl disable firewalld
setenforce 0

借用1.6版本的部分依赖库，懒得区分什么是刚需，copy一下直接贴过来了

yum install -y http://files.freeswitch.org/freeswitch-release-1-6.noarch.rpm epel-release

yum install -y git gcc-c++ autoconf automake libtool wget python ncurses-devel zlib-devel libjpeg-devel openssl-devel e2fsprogs-devel sqlite-devel libcurl-devel pcre-devel speex-devel ldns-devel libedit-devel libxml2-devel libyuv-devel opus-devel libvpx-devel libvpx2* libdb4* libidn-devel unbound-devel libuuid-devel lua-devel libsndfile-devel yasm-devel

安装lua5.2及以上版本

1.CentOS7默认已经安装了5.1.4 然并卵，freeswitch1.4以后就需要5.2以上lua来支持了,不然后期调试mysql lua会带来恶心的感觉。

①查看当前lua版本号：

lua -v

Lua 5.1.4  Copyright (C) 1994-2008 Lua.org, PUC-Rio

②查看lua和luac的位置：

which lua luac

/usr/bin/lua
/usr/bin/luac

2.编译Lua5.3版本

①下载lua-5.3.5.tar.gz

②make linux

出现错误：lua.c:80:31: fatal error: readline/readline.h: No such file or directory

表示需要安装依赖库：yum install readline-devel

③make install

cd src && mkdir -p /usr/local/bin /usr/local/include /usr/local/lib /usr/local/man/man1 /usr/local/share/lua/5.3 /usr/local/lib/lua/5.3
cd src && install -p -m 0755 lua luac /usr/local/bin
cd src && install -p -m 0644 lua.h luaconf.h lualib.h lauxlib.h lua.hpp /usr/local/include
cd src && install -p -m 0644 liblua.a /usr/local/lib
cd doc && install -p -m 0644 lua.1 luac.1 /usr/local/man/man1

可以看到，lua和luac被安装到了/usr/local/bin中

④lua -v查看版本，发现还是旧的版本，那我们就将/usr/bin中的lua和luac删除，然后将/usr/local/bin中的lua和luac创建一个ln到/usr/bin中即可

cd /usr/bin

rm -rf lua luac

ln -s /usr/local/bin/lua /usr/bin/lua

ln -s /usr/local/bin/luac /usr/bin/luac

lua -v

Lua 5.3.3  Copyright (C) 1994-2016 Lua.org, PUC-Rio

安装mod_av支持的lib

要支持h264视频通话，所以需要单独安装
mod_av 依赖libav, libav需要 x264 lib才能支持h264。

先下载源码
https://libav.org/
https://download.videolan.org/pub/videolan/x264/snapshots/

cd /usr/loca/src
git clone https://git.videolan.org/git/x264.git
wget https://libav.org/releases/libav-12.3.tar.gz
tar -zxvf libav-12.3.tar.gz

因为编译x264会提示
Found no assembler
Minimum version is nasm-2.13
所以需要手动安装 nasm 因为centos7自带的版本不够，
下载一个顺眼的版本 来三部曲安装吧
https://www.nasm.us/pub/nasm/releasebuilds/

wget https://www.nasm.us/pub/nasm/releasebuilds/2.14/nasm-2.14.tar.gz
tar -zxvf nasm-2.14.tar.gz
cd nasm-2.14
./configure
make
make install
cd ../x264
./configure --enable-shared --enable-static --disable-opencl
make
make install
cp /usr/local/lib/pkgconfig/x2* /usr/lib64/pkgconfig #否则libav在configure时会提示ERROR:x264 not found

libav编译时出错：
libavcodec/libx264.c: In function ‘X264_frame’:
libavcodec/libx264.c:246:9: error: ‘x264_bit_depth’ undeclared (first use in this function)
if (x264_bit_depth > 8)
^
libavcodec/libx264.c:246:9: note: each undeclared identifier is reported only once for each function it appears in
libavcodec/libx264.c: In function ‘X264_init_static’:
libavcodec/libx264.c:707:9: error: ‘x264_bit_depth’ undeclared (first use in this function)
if (x264_bit_depth == 8)
看了一圈没几个正经解决方案，参考x264对ffmpeg的补丁解决 http://git.videolan.org/?p=ffmpeg.git;a=patch;h=2a111c99a60fdf4fe5eea2b073901630190c6c93

 static av_cold void X264_init_static(AVCodec *codec)
 {
-    if (x264_bit_depth == 8)
+    if (X264_BIT_DEPTH == 8)
         codec->pix_fmts = pix_fmts_8bit;
-    else if (x264_bit_depth == 9)
+    else if (X264_BIT_DEPTH == 9)
         codec->pix_fmts = pix_fmts_9bit;
-    else if (x264_bit_depth == 10)
+    else if (X264_BIT_DEPTH == 10)
         codec->pix_fmts = pix_fmts_10bit;
}

cd ../libav-12.3
./configure --enable-shared --enable-libx264 --enable-gpl
make
make install
cp /usr/local/lib/pkgconfig/*.pc /usr/lib64/pkgconfig/
cp -f /usr/local/lib/* /usr/lib64/

增加mod_nuimrcp模块

编辑 vim ./build/modules.conf.in
修改 #applications/mod_av为applications/mod_av
修改 #asr_tts/mod_unimrcp 为 asr_tts/mod_unimrcp

安装odbc

因为后面会涉及到odbc的安装，所以先安装odbc

yum install -y unixODBC unixODBC-devel mysql-connector-odbc

安装完成后编辑/etc/odbcinst.ini

# Example driver definitions
 
# Driver from the postgresql-odbc package
# Setup from the unixODBC package
[PostgreSQL]
Description     = ODBC for PostgreSQL
Driver          = /usr/lib/psqlodbcw.so
Setup           = /usr/lib/libodbcpsqlS.so
Driver64        = /usr/lib64/psqlodbcw.so
Setup64         = /usr/lib64/libodbcpsqlS.so
FileUsage       = 1
 
 
# Driver from the mysql-connector-odbc package
# Setup from the unixODBC package
[MySQL]
Description     = ODBC for MySQL
Driver          = /usr/lib64/libmyodbc5.so
Setup           = /usr/lib64/libodbcmyS.so
Driver64        = /usr/lib64/libmyodbc5.so
Setup64         = /usr/lib64/libodbcmyS.so
FileUsage       = 1

编辑/etc/odbc.ini

[freeswitch]
Description=MySQL realtime database
Driver=/usr/lib64/libmyodbc5.so
SERVER =数据库地址
PORT =3306
DATABASE = freeswitch
OPTION  =67108864
CHARSET = UTF8
USER = 数据库账号
PASSWORD = 数据库密码
Threading = 0

输入：isql -v freeswitch测试是否能够连通

安装php–为freeswitch后期扩展开发预备

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

//查看
yum search php72w
//安装php以及扩展
yum install php72w php72w-fpm php72w-cli php72w-common php72w-devel php72w-gd php72w-pdo php72w-mysql php72w-mbstring php72w-bcmath

编译freeswitch 1.9

configure中间出现的错误：

configure: error: “Cannot build without libtiff (does your system require a libtiff-devel package?)”

yum install -y  libtiff-devel

make中间出现的错误：

making all mod_signalwire
make[4]: Entering directory `/usr/local/src/freeswitch/src/mod/applications/mod_signalwire'
Makefile:916: *** You must install libks to build mod_signalwire.  Stop.
make[4]: Leaving directory `/usr/local/src/freeswitch/src/mod/applications/mod_signalwire'
make[3]: *** [mod_signalwire-all] Error 1

本来想粗暴注释掉mod_signalwire解决，但逃避不是办法，解决一下吧
需要安装 libks 和 signalwire-c
https://github.com/signalwire/libks
https://github.com/signalwire/signalwire-c

libks需要cmake (Minimum version 3.6.2)，比较坑，所以手动安装cmake
https://cmake.org/files/ 这里是编译安装，也可以自己下载编译好的直接用
https://cmake.org/files/v3.13/cmake-3.13.3-Linux-x86_64.tar.gz 建议直接下载编译好的，编译时间很恶心

yum install libatomic.x86_64   #libks还会提示少libatomic

cd /usr/local/src
wget https://cmake.org/files/v3.13/cmake-3.13.3.tar.gz
tar -zxvf cmake-3.13.3.tar.gz
cd cmake-3.13.3 
./bootstrap
gmake
make install

cd /usr/local/src
git clone https://github.com/signalwire/libks.git
cd libks
cmake .
make
make install
 cp /usr/lib/pkgconfig/libks.pc /usr/lib64/pkgconfig/   #这个比较坑爹，不然还是还找不到libks模块
cd /usr/local/src
git clone https://github.com/signalwire/signalwire-c.git
cd signalwire-c
cmake .
make
make install
cp /usr/local/lib/pkgconfig/*.pc /usr/lib64/pkgconfig/
cp -f /usr/local/lib/* /usr/lib64/

cd /usr/local/freeswitch
./bootstrap.sh -j
./configure --enable-core-odbc-support  #如果读者不想使用mysql管理，只需要执行./configure即可
make
make install

ln -sf /usr/local/freeswitch/bin/freeswitch /usr/local/bin/
ln -sf /usr/local/freeswitch/bin/fs_cli /usr/local/bin/

//安装声音文件
make cd-sounds-install
make cd-moh-install

在fs上开启rport功能

<paramname="NDLB-force-rport" value="true"/>

设置rtp自动调整功能

<paramname="disable-rtp-auto-adjust" value="false"/>

防火墙和NAT设置

云端映射/nat设置
需要打开的端口：

udp     16384:32768
udp     4569
udp     5060
tcp     5060
udp     5080
tcp     5080
tcp     8000
udp     8000

配置conf/autoload_configs/verto.conf.xml

<param name="ext-rtp-ip" data="外网ip">

配置conf/sip_profiles/internal.xml

<param name="aggressive-nat-detection" value="true"/>
<param name="multiple-registrations" value="true"/>
<param name="ext-rtp-ip" value="外网ip"/>
<param name="ext-sip-ip" value="外网ip"/>
<param name="NDLB-received-in-nat-reg-contact" value="true"/>
<param name="NDLB-force-rport" value="true"/>
<param name="NDLB-broken-auth-hash" value="true"/>
<param name="enable-timer" value="false"/>
<param name="auth-calls" value="true"/>

配置conf/sip_profiles/external.xml

<param name="aggressive-nat-detection" value="true"/>
<param name="ext-rtp-ip" value="外网ip"/>
<param name="ext-sip-ip" value="外网ip"/>
<param name="NDLB-force-rport" value="true"/>

配置conf/autoload_configs/switch.conf.xml

<param name="rtp-start-port" value="16384"/>
<param name="rtp-end-port" value="32768"/>

加载mod_av

启动freeswitch，在控制命令中输入:

load mod_av

或者修改/usr/local/freeswitch/conf/autoload_configs下的modules.conf.xml

取消掉mod_av的注释即可（该方法是修改启动时加载项，修改后重启FreeSwitch即可）

进入/usr/local/freeswitch/bin目录下

./freeswitch -nonat

连接MySQL数据库

FreeSwitch默认是使用的SQLite数据库，这里我们将使用MySQL数据库来管理FreeSwitch中的账户，并实现账户之间能够互相拨打电话。

首先进入到/usr/local/freeswitch/conf/autoload_configs目录下，编辑lua.conf.xml文件

在<setting> 标签下添加如下的代码：

    <param name="xml-handler-script" value="gen_dir_user_xml.lua"/>
    <param name="xml-handler-bindings" value="directory"/>

然后在/usr/local/freeswitch/scripts/下创建gen_dir_user_xml.lua文件

freeswitch.consoleLog("notice", "Debug from gen_dir_user_xml.lua, provided params:n" .. params:serialize() .. "n")

local req_domain = params:getHeader("domain")
local req_key = params:getHeader("key")
local req_user = params:getHeader("user")
local dbh = freeswitch.Dbh("freeswitch","sip","password")

if dbh:connected() == false then
freeswitch.consoleLog("notice", "gen_dir_user_xml.lua cannot connect to database" .. dsn .. "n")
return
end
XML_STRING =
[[<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<document type=" freeswitch/xml">
<section name="directory">
<domain name="]] .. req_domain .. [[">
<user id="]] .. req_user .. [[">
<params>
<param name="password" value=" FreeSwitch+ysyhL9T"/>
<param name="dial-string" value="{sip_invite_domain=${dialed_domain},
presence_id=${dialed_user}@${dialed_domain}}${sofia_contact(${dialed_user}@${dialed_domain})}"/>
</params>
<variables>
<variable name="user_context" value="default"/>
</variables>
</user>
</domain>
</section>
</document>]]
local my_query = string.format("select pass_word,user_context from users where sip_id='%s' limit 1", req_user)
assert (dbh:query(my_query, function(u) -- there will be only 0 or 1 iteration (limit 1)
freeswitch.consoleLog("NOTICE",u.pass_word.."n")
XML_STRING =
[[<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<document type=" freeswitch/xml">
<section name="directory">
<domain name="]] .. req_domain .. [[">
<user id="]] .. req_user .. [[">
<params>
<param name="password" value="]] .. u.pass_word .. [["/>
<param name="dial-string" value="{sip_invite_domain=${dialed_domain},
presence_id=${dialed_user}@${dialed_domain}}${sofia_contact(${dialed_user}@${dialed_domain})}"/>
</params>
<variables>
<variable name="user_context" value="]] .. u.user_context .. [["/>
</variables>
</user>
</domain>
</section>
</document>]]
end))

编辑/usr/local/freeswitch/conf/directory/default.xml
删除如下代码

    <group name="default">
        <users>
          <X-PRE-PROCESS cmd="include" data="default/*.xml"/>
        </users> 	
     </group>

MySQL数据库中，创建freeswitch数据库，添加如下的表，并插入元素：

CREATE DATABASE IF NOT EXISTS freeswitch default charset utf8 COLLATE utf8_general_ci;

drop table if exists `users`;

CREATE TABLE IF NOT EXISTS `users` (
    `user_id` int(11) NOT NULL AUTO_INCREMENT,
    `domain` varchar(90) NOT NULL COMMENT '域',
    `sip_id` varchar(90) NOT NULL COMMENT '音视频聊天ID',
    `mail_box` varchar(90) NOT NULL COMMENT '邮箱',
    `number_alias` varchar(90) NOT NULL COMMENT '',
    `pass_word` varchar(255) NOT NULL COMMENT '密码',
    `dial_string` varchar(90) NOT NULL COMMENT '',
    `user_context` varchar(90) NOT NULL COMMENT '',
    `author_id` int(11) NOT NULL COMMENT '作者',
    `create_time` int(11) NOT NULL COMMENT '创建时间',
    `del_time` int(11) NOT NULL COMMENT '删除时间',
    `handler_id` int(11) NOT NULL COMMENT '处理人',
PRIMARY KEY (`user_id`),
KEY `sip_id` (`sip_id`),
KEY `author_id` (`author_id`),
KEY `create_time` (`create_time`),
KEY `del_time` (`del_time`),
KEY `handler_id` (`handler_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC COMMENT='用户';
 
INSERT INTO `users` VALUES 
    (1, '', '8001', '', '', '2345', '', 'default', 0, unix_timestamp(now()), 0, 0),
    (2, '', '8002', '', '', '2345', '', 'default', 0, unix_timestamp(now()), 0, 0),
    (3, '', '8003', '', '', '2345', '', 'default', 0, unix_timestamp(now()), 0, 0),
    (4, '', '8004', '', '', '2345', '', 'default', 0, unix_timestamp(now()), 0, 0);

修改拨号计划

编辑/usr/local/freeswitch/conf/dialplan/default.xml

    <extension name="Local_Extension2">
        <condition field="destination_number" expression="^([0-9][0-9][0-9][0-9])$">
            <action application="export" data="dialed_extension=$1"/>
            <action application="set" data="call_timeout=10"/>
            <action application="set" data="hangup_after_bridge=true"/>
            <action application="set" data="continue_on_fail=false"/>
            <action application="bridge" data="user/${dialed_extension}@${domain_name}"/>
        </condition>
    </extension>

PS：该行代码需要放在’<context name=“default”>’ 后面

在FreeSwitch控制台按F6或者输入reloadxml，此时可以使用X-Lite或者Zoiper进行测试：

账号1输入8003，密码12345，Domain输入虚拟机的IP地址

账号2输入8004，密码12345，Domain输入虚拟机的IP地址

测试互打是否能够通话。

支持视频通话

编辑/usr/local/freeswitch/conf/vars.xml

    <X-PRE-PROCESS cmd="set" data="global_codec_prefs=OPUS,G722,PCMU,PCMA,VP8,H263,H264"/>
    <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=OPUS,G722,PCMU,PCMA,VP8,H263,H264"/>

编辑/usr/local/freeswitch/conf/sip_profiles/internal.xml文件 如下：

    <param name="inbound-proxy-media" value="true"/>     

fsctl shutdown 控制台退出并关闭
在FreeSwitch控制台按F6或者输入reloadxml即可支持视频通话功能。

测试时使用linphone,X-Lite或者Zoiper，通话时选择视频通话，即可。
