首先安装点基础套件

sudo apt install -y ffmpeg libx264-dev libssl-dev yasm cmake

从源码编译安装ffmpeg

以上命令已经安装了发布版的ffmpeg,不过如果有需要,可以按照源码版的编译安装

git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg
cd ffmpeg
sudo ./configure --enable-shared --prefix=/usr/local/ffmpeg
make
sudo make install

编译安装nginx

sudo git clone https://github.com/arut/nginx-rtmp-module.git
sudo wget http://nginx.org/download/nginx-1.16.1.tar.gz
sudo tar -xvf nginx-1.16.1.tar.gz
cd nginx-1.16.1
sudo  ./configure --prefix=/usr/local/nginx  --add-module=../nginx-rtmp-module  --with-cc-opt="-Wimplicit-fallthrough=0"
make -j4
make install

nginx配置文件

user www-data;
worker_processes auto;
pid /tmp/nginx.pid;

events {
  worker_connections 768;
  # multi_accept on;
}

rtmp {
    server {
        listen 1335;
        application rtmp {
            live on;
            max_connections 1024;
        }
        application zbcs {
            live on;
            record off;
        }
        application hls{
            live on;
            hls on;
            hls_path /rtmp/;
            hls_fragment 1s;
        }
    }
}

写 systemd 配置文件

vim /usr/lib/systemd/system/nginx.service
