1. 安装 freeswitch 库
git clone https://github.com/signalwire/freeswitch.git
2. 安装环境依赖
apt-get install libedit-dev libldns-dev libpcre3-dev libspeexdsp-dev libspeex-dev libcurl4-openssl-dev libopus-dev libncurses5-dev libtiff-dev libjpeg-dev libssl-dev libsqlite3-dev build-essential automake autoconf git-core wget libtool lua5.1 liblua5.1-dev libsndfile1-dev yasm libsndfile-dev libtool-bin sqlite3 libavresample-dev libswscale-dev uuid-dev
3 . 安装freeswitch
sudo ./bootstrap.sh sudo ./configure sudo make install
问题归纳解决：
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
解决办法：
1. 安装cmake
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 sudo ./bootstrap sudo make sudo make install
2. 安装libks
cd /usr/local/src git clone https://github.com/signalwire/libks.git cd libks sudo cmake . sudo make sudo make install sudo mkdir -p /usr/lib64/pkgconfig/sudo cp /usr/lib/pkgconfig/libks.pc /usr/lib64/pkgconfig/
3. 安装signalwire-c
cd /usr/local/src git clone https://github.com/signalwire/signalwire-c.git cd signalwire-c sudo cmake . sudo make sudo make install sudo cp /usr/local/lib/pkgconfig/*.pc /usr/lib64/pkgconfig/ sudo cp -f /usr/local/lib/* /usr/lib64/
然后再重新编译安装freeswitch，没有意外的话可以正常安装freeswitch
cd /usr/local/freeswitch sudo ./bootstrap.sh -j sudo ./configure --enable-core-odbc-support #如果读者不想使用mysql管理，只需要执行./configure即可 sudo make sudo make install
成功的界面如下

注：freeswitch一开始安装好 默认会给你配置好20个account （1000-1019），密码统一是1234，这个可以在freeswitch/conf/vars.xml里面修改
