2. 安装cmake

yum install -y libxml2 libxml2-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel zstd libzstd-devel curl libcurl-devel libpng libpng-devel

wget https://github.moeyy.xyz/https://github.com/Kitware/CMake/releases/download/v3.23.0/cmake-3.23.0.tar.gz

tar -zxvf cmake-3.23.0.tar.gz && cd cmake-3.23.0 && ./configure --prefix=/usr/local/cmake-3.23.0
gmake -j
gmake install

如果报下面错误

g++: internal compiler error: Killed (program cc1plus)
Please submit a full bug report,
with preprocessed source if appropriate.
See http://bugzilla.redhat.com/bugzilla for instructions.
gmake[2]: *** [Source/CMakeFiles/CMakeLib.dir/cmComputeLinkInformation.cxx.o] Error 4
gmake[2]: *** Waiting for unfinished jobs....
[ 65%] Building CXX object Source/CMakeFiles/CMakeLib.dir/cmGlobVerificationManager.cxx.o

可以修改为下面，其中-j后面的值是cpu内核数

gmake -j4

配置环境变量

touch /etc/profile.d/cmake.sh
chmod 777 /etc/profile.d/cmake.sh 
echo -e '\nexport PATH=/usr/local/cmake-3.23.0/bin:$PATH\n' >> /etc/profile.d/cmake.sh
source /etc/profile.d/cmake.sh

3. 安装libks

yum install libatomic
git clone -b v1.x https://github.moeyy.xyz/https://github.com/signalwire/libks.git
cd libks
cmake .
make -j4

4. 安装signalwire-c

git clone -b v1.x https://github.moeyy.xyz/https://github.com/signalwire/signalwire-c.git
cd signalwire-c/
cmake .
make -j4
make install
ln -sf /usr/local/lib64/pkgconfig/signalwire_client.pc /usr/lib64/pkgconfig/signalwire_client.pc

5. 安装x264

git clone http://git.videolan.org/git/x264.git
cd x264
./configure --disable-asm

ldconfig

7. 编译安装freeswitch

下载并解压

wget https://files.freeswitch.org/releases/freeswitch/freeswitch-1.10.2.-release.tar.gz
tar -zxvf freeswitch-1.10.2.-release.tar.gz

编译前修改一些系统配置

cd /etc/yum.repos.d/ && vim linuxtech.repo

[linuxtech]
name=LinuxTECH 
baseurl=http://pkgrepo.linuxtech.net/el6/release/ 
enabled=1 
gpgcheck=1 
gpgkey=http://pkgrepo.linuxtech.net/el6/release/RPM-GPG-KEY-LinuxTECH.NET

安装opus

yum install libopus-devel -y 
wget https://archive.mozilla.org/pub/opus/opus-1.3.tar.gz 
tar -zxvf opus-1.3.tar.gz && cd opus-1.3 
./configure 
make -j4
make install

编译并安装

cd freeswitch-1.10.2.-release
./configure 
make -j4
make install

设置软链接

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

启动freeswitch

freeswitch -nc -nonat

停止freeswitch

freeswitch -stop 

进入freeswitch控制台

fs_cli
status  # 查看运行状态
sofia status profile internal reg  # 查看用户是否注册
/exit  # 退出控制台
