前言

  以前一直在CentOS 7.6上做FreeSwitch的开发，目前想转到ubuntu 22.04上面，有两个原因，第一是centos停止维护了，第二个原因是FreeSwitch1.10的内置mysql连接在centos上面安装还是比较麻烦（这个如果大家有兴趣，我会专门再写一篇）。网上在ubuntu 22.04上安装FreeSwitch的教程比较少，因此写出来供大家参考。敲字不易，转载请注明出处。

一、准备工作

1. 更新ubuntu,

sudo apt update -y 
suso apt upgrade -y 
sudo DEBIAN_FRONTEND=noninteractive apt-get install -y --no-install-recommends tzdata

    2. 安装FreeSwitch依赖库，

sudo apt install unixodbc-dev curl wget git subversion build-essential autoconf automake libtool libncurses5 libncurses5-dev make libjpeg-dev libtool libtool-bin libsqlite3-dev libpcre3-dev libspeexdsp-dev libldns-dev libedit-dev yasm liblua5.2-dev libopus-dev cmake libtiff-dev libcodec2-dev libcodec2-dev portaudio19-dev libmagickcore-dev libmp3lame-dev libmpg123-dev libshout3-dev libvlc-dev libpq-dev libmariadb-dev libldap2-dev erlang librabbitmq-dev libsmpp34-dev libyaml-dev libmongoc-dev libopencv-dev libmemcached-dev libavformat-dev libh2o-dev libsoundtouch-dev libhiredis-dev libopus-dev autoconf automake devscripts gawk gettext libcurl4-openssl-dev libdb-dev libedit-dev libgdbm-dev libldns-dev libncurses5-dev libopus-dev libopus-ocaml libpcre3-dev libperl-dev libpq-dev libspeex-dev libspeexdsp-dev libssl-dev libtiff5-dev libtool libtool-bin libvorbis0a libogg0 libsqlite3-dev libogg-dev libvorbis-dev portaudio19-dev libshout3-dev libmpg123-dev libmp3lame-dev yasm libbsd-dev flite flite1-dev libflite1 liblua5.2-0 liblua5.2-dev lua5.2 luarocks libsndfile-dev -y

    3. 安装Gcc 10, 系统默认版本过高，编译可能会出问题，

sudo rm -rf /usr/bin/gcc 
sudo rm -rf /usr/bin/g++

sudo apt install gcc-10 g++-10 cpp-10 -y 
sudo ln -s /usr/bin/gcc-10 /usr/bin/gcc 
sudo ln -s /usr/bin/g++-10 /usr/bin/g++

二、编译安装

    所有源码我们选择放在/opt目录下，选择放在其它目录也可以。

    1. 编译安装Spandsp和Sofia-sip，这两个库是需要单独安装的,

cd /opt
sudo git clone https://github.com/freeswitch/spandsp /opt/spandsp
cd /opt/spandsp
sudo ./bootstrap.sh
sudo ./configure
sudo make
sudo make install 


cd /opt
sudo git clone https://github.com/freeswitch/sofia-sip.git /opt/sofia-sip
cd /opt/sofia-sip
sudo ./bootstrap.sh
sudo ./configure
sudo make
sudo make install

sudo /sbin/ldconfig -v  

     2. 编译安装libks和signalwire

cd /opt
sudo git clone https://github.com/signalwire/libks.git
cd libks
sudo cmake .
sudo make
sudo make install

cd /opt
git clone https://github.com/signalwire/signalwire-c.git
cd signalwire-c
sudo cmake .
sudo make
sudo make install

    3. 编译安装FreeSwitch,

cd /opt
sudo git clone https://github.com/signalwire/freeswitch.git -b v1.10
cd /opt/freeswitch
sudo ./bootstrap.sh -j
sudo CFLAGS=-Wno-error ./configure --prefix=/usr/local/freeswitch --enable-core-odbc-support --enable-zrtp

    这时可以选在内置mysql的连接，修改/opt/freeswitch/modules.conf

        将mod_pgsql注释掉，打开mod_mariadb

        #databases/mod_pgsql

        databases/mod_mariadb

    然后开始编译和安装，

sudo make
sudo make install

    建立符号连接，

sudo ln -s /usr/local/freeswitch/bin/freeswitch /usr/bin/freeswitch
sudo ln -s /usr/local/freeswitch/bin/fs_cli /usr/bin/fs_cli

    启动，

sudo freeswitch -nc

    启动FreeSwitch客户端，

fs_cli

总结

    本文详细描述了Freeswitch在ubuntu 22.04上的安装过程，按文中步骤应该能顺利安装完成，有任何问题欢迎探讨，下一篇文章将会讲解FreeSwitch的基本配置。
