wget https://nginx.org/download/nginx-1.20.2.tar.gz
#镜像站下载
wget https://pan.pengcheng.team/d/Tool/FFmpeg/ffmpeg-4.1.tar.gz?sign=B3BXB1XQ5nk22k4yfV_fCF7bYupNYZSCAjt9LG89qaQ=:0 -O ffmpeg-4.1.tar.gz

2.安装依赖

yum install -y nasm pcre-devel openssl openssl-devel gcc g++ gcc-c++ make

2、安装FFmpeg

1.解压安装包

tar -xvf ffmpeg-4.1.tar.gz
cd ffmpeg-4.1
tar -xvf nginx-1.20.2.tar.gz

2.编辑安装

./configure --prefix=/usr/local/ffmpeg
make

source /etc/profile

3、安装Nginx

1.解压安装包

tar -xvf nginx-1.20.2.tar.gz

make install

3.修改Nginx配置

修改配置文件：nginx/conf/nginx.conf

    location /hls {

      types {  
        #application/x-mpegURL m3u8;
        application/vnd.apple.mpegurl m3u8 ;  
        video/mp2t ts ;  
      }
      alias   /home/wwwroot/ffmpeg; 
      add_header Cache-Control no-cache ;
      add_header Access-Control-Allow-Origin *;
    }
