nginx-rtmp-module 是一个用于 Nginx 的第三方模块,它扩展了 Nginx 服务器的功能,使其能够处理实时流媒体数据,特别是支持 RTMP (Real-Time Messaging Protocol) 协议。RTMP 是 Adobe Systems 开发的一种协议,常用于实时音视频通信,尤其是在直播场景中。
这里推荐另一种开源的直播系统owncast,网址: https://owncast.online/
一、安装Nginx
1、下载Nginx
cd /usr/local/src wget http://nginx.org/download/nginx-1.13.6.tar.gz
2、解压
tar -zxvf nginx-1.13.6.tar.gz
3、安装编译需要的工具
yum -y install gcc gcc-c++ openssl openssl-devel zlib zlib-devel pcre pcre-devel
4、编译Nginx
cd nginx-1.13.6 # 编译 ./configure --prefix=/usr/local/nginx \ --with-http_stub_status_module \ --with-http_ssl_module \ --with-http_realip_module \ --with-http_sub_module \ --with-http_gzip_static_module
5、安装
make && make install
二、安装Nginx RTMP模块
1、下载
cd /usr/local/src wget https://github.com/arut/nginx-rtmp-module/archive/refs/tags/v1.2.2.tar.gz
2、解压
tar -zxvf v1.2.2.tar.gz
3、编译
cd nginx-1.13.6 # 编译 ./configure --add-module=/usr/local/src/nginx-rtmp-module-1.2.2 \ --with-http_ssl_module
4、安装
make && make install
三、配置
1、Nginx配置RTMP和HLS
vim /usr/local/nginx/conf/nginx.conf # 修改如下 rtmp_auto_push on; rtmp { server { listen 1935; # 监听端口 1935,用于 RTMP 数据流传输 chunk_size 4000; # 数据传输分块大小 application live { live on; # 开启 RTMP 直播功能 hls on; # 开启 HLS 功能 hls_fragment 2s; # 每个 HLS 分片的时长为 2 秒。 hls_playlist_length 6s; # HLS 播放列表长度为 6 秒 hls_path /usr/local/nginx/html/hls; # HLS 分片文件存储路径 } } } worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 80; server_name localhost; location / { root html; index index.html index.htm; } location /stat { rtmp_stat all; # Use this stylesheet to view XML as web page # in browser rtmp_stat_stylesheet stat.xsl; } location /stat.xsl { # XML stylesheet to view RTMP stats. # Copy stat.xsl wherever you want # and put the full directory path here root /usr/local/src/nginx-rtmp-module-1.2.2; } location /hls { # Serve HLS fragments types { application/vnd.apple.mpegurl m3u8; video/mp2t ts; } root /usr/local/nginx/html; add_header Cache-Control no-cache; } } }
2、为Nginx配置启动
vim /lib/systemd/system/nginx.service # 查看 [Unit] Description=nginx After=network.target [Service] Type=forking ExecStart=/usr/local/nginx/sbin/nginx ExecReload=/usr/local/nginx/sbin/nginx reload ExecStop=/usr/local/nginx/sbin/nginx quit PrivateTmp=true [Install] WantedBy=multi-user.target
3、启动Nginx
systemctl start nginx
四、直播演示
1、用OBS推流,打开设置,直播
服务器:rtmp://ip:1935/live(live目录是Nginx中定义好的)
推流码:demo(自定义)
2、在OBS中添加采集来源,点击开启直播
3、客户端下载 VLC软件,拉流实现观看直播
下载地址:https://www.videolan.org/
打开虚拟机端 VLC 客户端,媒体 > 打开网络串流
(1)RTMP协议:rtmp://ip/live/demo
(2)HLS协议:http://ip/hls/demo.m3u8
知识点:
- HLS可以在手机H5页面、微信公众号上播放,延迟10秒以上
- RTMP依赖Flash Player才能播放,延迟3秒左右
4、数据统计:ip://stat
