如何基于Nginx搭建流媒体服务器

HLS是何基最常见的视频流媒体协议，HLS是搭建一种自适应流媒体技术，可以根据用户的流媒设备和网络条件对播放媒体内容，以获得最佳播放性能。体服

Nginx RTMP是服务器租用何基一个Nginx插件，支持将RTMP和HLS流添加到媒体服务器。搭建以ubuntu为力，流媒下面介绍如何安装使用nginx Rtmp 插件的体服步骤。

1.更新apt库

复制apt-get update1.

2.安装ffmpeg等所需要的何基软件

复制apt-get install -y git build-essential ffmpeg libpcre3 libpcre3-dev libssl-dev zlib1g-dev1.

3.下载RTMP模块

复制git clone https://github.com/sergey-dryabzhinsky/nginx-rtmp-module.git1.

4.下载并解压Nginx

复制wget http://nginx.org/download/nginx-1.17.6.tar.gztar -xf nginx-1.17.6.tar.gzcd nginx-1.17.61.

5.配置Nginx拷贝一份nginx配置文件出来

复制mv /usr/local/nginx/conf/nginx.confnano /usr/local/nginx/conf/nginx.conf1.

将以下内容复制到nginx.conf文件中：

复制 worker_processes auto; events { worker_connections 1024; } # RTMP configuration rtmp { server { listen 1935; # Listen on standard RTMP portchunk_size 4000; application show { live on; # Turn on HLS hls on; hls_path /mnt/hls/; hls_fragment 3; hls_playlist_length 60; # disable consuming the stream from nginx as rtmpdeny play all; } } } http { sendfile off; tcp_nopush on; directio 512; default_type application/octet-stream; server { listen 8080; location / { # Disable cache add_header Cache-Control no-cache; # CORS setup add_header Access-Control-Allow-Origin * always; add_header Access-Control-Expose-Headers Content-Length; # allow CORS preflight requests if ($request_method = OPTIONS) { add_header Access-Control-Allow-Origin *; add_header Access-Control-Max-Age 1728000; add_header Content-Type text/plain charset=UTF-8; add_header Content-Length 0; return 204; } types { application/dash+xml mpd; application/vnd.apple.mpegurl m3u8; video/mp2t ts; } root /mnt/; } } }1.2.3.4.5.6.7.8.9.10.11.12.13.14.15.16.17.18.19.20.21.22.23.24.25.26.27.28.29.30.31.32.33.34.35.36.37.38.39.40.41.42.43.44.45.46.47.48.49.50.51.52.53.54.55.56.

6.启动Nginx

复制/usr/local/nginx/sbin/nginx1.

7.测试

该服务器可以从各种来源进行流式传输，包括静态文件、亿华云搭建网络摄像头等。流媒由于上面的体服步骤中安装了ffmpeg，我们可以将example-vid.mp4视频文件流式传输到http服务http://localhost/show/stream。何基

复制ffmpeg -re -i example-vid.mp4 -vcodec libx264 -vprofile baseline -g 30 -acodec aac -strict -2 -f flv rtmp://localhost/show/stream1.

8.最后

根据服务的搭建需求，可以将http服务集成到您的流媒应用程序或者网页中。高防服务器
