yum install -y http://files.freeswitch.org/freeswitch-release-1-6.noarch.rpm epel-release
（1）
yum install -y git alsa-lib-devel autoconf automake bison broadvoice-devel bzip2 curl-devel libdb4-devel e2fsprogs-devel erlang flite-devel g722_1-devel gcc-c++ gdbm-devel gnutls-devel ilbc2-devel ldns-devel libcodec2-devel libcurl-devel libedit-devel libidn-devel libjpeg-devel libmemcached-devel libogg-devel libsilk-devel libsndfile-devel libtheora-devel libtiff-devel libtool libuuid-devel libvorbis-devel libxml2-devel lua-devel lzo-devel mongo-c-driver-devel ncurses-devel net-snmp-devel openssl-devel opus-devel pcre-devel perl perl-ExtUtils-Embed pkgconfig portaudio-devel postgresql-devel python-devel python-devel soundtouch-devel speex-devel sqlite-devel unbound-devel unixODBC-devel wget which yasm zlib-devel libshout-devel libmpg123-devel lame-devel（2）
yum install libjpeg-devel lua-devel libsndfile-devel libyuv-devel git libtool -y（3）
yum install kernel-headers –y可以直接下载或者安装包解压方式安装，建议用第二种，第一种没有尝试
（1）下载安装：git clone -b v1.6 https://freeswitch.org/stash/scm/fs/freeswitch.git freeswitch
（2）解压包安装：https://download.csdn.net/download/mokeily99/76668375 免费下载
以下按照（2）方式安装，将下载下来的freeswitch-1.6.0.tar.gz压缩包上传至/usr/local/src目录下。
运行以下命令解压
cd /usr/local/src
tar -zxvf /usr/local/src/freeswitch-1.6.0.tar.gz解压后目录下会出现freeswitch-1.6.0文件夹，下面安装libyuv-master、libvpx-master、libpng-maste三个lib
安装libyuv-master
下载libyuv-master.zip：libyuv-master.zip-其它文档类资源-CSDN下载
cd /usr/local/src/freeswitch-1.6.0/libs
midir libyuv将libyuv-master.zip上传至/usr/local/src/freeswitch-1.6.0/libs/libyuv
cd /usr/local/src/freeswitch-1.6.0/libs/libyuv
unzip libyuv-master.zip
make -f linux.mk CXXFLAGS="-fPIC -O2 -fomit-frame-pointer -Iinclude/"
make install
cp /usr/lib/pkgconfig/libyuv.pc /usr/lib64/pkgconfig/安装libvpx-master
下载libvpx-master.zip：libvpx-master-其它文档类资源-CSDN下载
cd /usr/local/src/freeswitch-1.6.0/libs
midir libvpx将libvpx-master.zip上传至/usr/local/src/freeswitch-1.6.0/libs/libvpx
cd /usr/local/src/freeswitch-1.6.0/libs/libvpx
unzip libvpx-master.zip
./configure --enable-pic --disable-static --enable-shared
make
make install
cp /usr/local/lib/pkgconfig/vpx.pc /usr/lib64/pkgconfig/
安装libpng-master
下载libpng-master.zip：libpng-master-其它文档类资源-CSDN下载
cd /usr/local/src/freeswitch-1.6.0/libs
midir libpng将libpng-master.zip上传至/usr/local/src/freeswitch-1.6.0/libs/libpng
cd /usr/local/src/freeswitch-1.6.0/libs/libpng
unzip libpng-master.zip
./configure
make
make install
cp /usr/local/lib/pkgconfig/libpng* /usr/lib64/pkgconfig/
编译
cd /usr/local/src/freeswitch-1.6.0
sh rebootstrap.sh
./configure
make
make install运行以上命令中间可能会好使几分钟
./configure后成功如下图
make后确保没有报错信息，如有错误信息确认libyuv-master、libvpx-master、libpng-master三个组件是否安装中出现错误。
make install后出现以下图成功
以上 成功后/usr/local下会出现freeswitch的目录
禁用IPV6
mv /usr/local/freeswitch/conf/sip_profiles/internal-ipv6.xml /usr/local/freeswitch/conf/sip_profiles/internal-ipv6.xml.bk
mv /usr/local/freeswitch/conf/sip_profiles/external-ipv6.xml /usr/local/freeswitch/conf/sip_profiles/external-ipv6.xml.bk添加启动软连接
ln -sf /usr/local/freeswitch/bin/freeswitch /usr/bin/
ln -sf /usr/local/freeswitch/bin/fs_cli /usr/bin/安装声音文件
cd /usr/local/src/freeswitch-1.6.0
make cd-sounds-install
make cd-moh-install声音文件安装会耗时很久，耐心等待
cd /usr/local/src/freeswitch-1.6.0/bin
freeswitch -c -nonat –rp以上启动为控制台启动，启动后可之间查看到控制台日志，方便调试
以上为常规freeswitch安装启动步骤，下篇记录百度Mrcp Server智能语音搭建及集成freeswitch步骤。如有疑问及合作邮箱联系mokeily99@126.com
