make && make install
#修改文件/etc/ld.so.conf,加入以下语句
vi /etc/ld.so.conf
/usr/local/x264
#保存退出
ldconfig
#如果这里不修改/etc/ld.so.conf的话，在运行ZLMediaKit的时候会报
#error while load shared libraries:libx264.s0.159

6. 安装libmp4v2-devel

wget http://springdale.princeton.edu/data/springdale/7/x86_64/os/Addons/Packages/libmp4v2-2.0.0-2.el7.x86_64.rpm

vi /etc/ld.so.conf
#加入以下语句
/usr/local/ffmpeg/lib/
#保存退出
ldconfig
#加入bash
vi ~/.bashrc
export PATH=$PATH:/usr/local/ffmpeg/bin
#保存退出
source ~/.bashrc
#查看ffmpeg版本
ffmpeg -version

六、编译安装ZLMediaKit

一、安装相关依赖

1. 安装libsrtp

wget https://codeload.github.com/cisco/libsrtp/tar.gz/refs/tags/v2.3.0
tar -xvzf libsrtp-2.3.0.tar.gz
cd libsrtp-2.3.0
# 指定openssl的安装目录
./configure --enable-openssl --with-openssl-dir=/usr/local/openssl
make -j8 && make install

2. 安装mysql

wget https://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
yum -y install mysql-community-server
#启动mysql
systemctl start mysqld.service

二、编译安装ZLMediaKit

1. 下载ZLM源码

#国内用户推荐从同步镜像网站gitee下载 
git clone --depth 1 https://gitee.com/xia-chu/ZLMediaKit
cd ZLMediaKit
#千万不要忘记执行这句命令
git submodule update --init

2. 编译

mkdir build
cd build
cmake .. -DENABLE_WEBRTC=true
-DOPENSSL_ROOT_DIR=/usr/local/openssl
-DOPENSSL_LIBRARIES=/usr/local/openssl/lib
cmake --build . --target MediaServer
# 最终输出
[ 96%] Built target test_rtcp_fci
[ 96%] Building CXX object tests/CMakeFiles/test_rtp.dir/test_rtp.cpp.o
[ 97%] Linking CXX executable ../../release/linux/Debug/test_rtp
[ 97%] Built target test_rtp
[ 97%] Building CXX object tests/CMakeFiles/test_wsServer.dir/test_wsServer.cpp.o
[ 97%] Linking CXX executable ../../release/linux/Debug/test_wsServer
[ 97%] Built target test_wsServer
[ 97%] Building CXX object tests/CMakeFiles/test_server.dir/test_server.cpp.o
[ 97%] Linking CXX executable ../../release/linux/Debug/test_server
[ 97%] Built target test_server
[ 98%] Built target jsoncpp
[ 98%] Linking CXX executable ../../release/linux/Debug/MediaServer
[100%] Built target MediaServer

编译完成后会在ZLMediaKit/release/linux/Debug目录下。修改指定配置文件即可启动

3. 在编译代码可能会遇到的问题
   无法找GCC的编译环境，使用的GCC编译环境不是GCC5.4的，还是原来的4.8.5版本。
   设置环境变量即可解决

export CC=/usr/local/bin/gcc
export GXX=/usr/local/bin/g++
