Nginx+rtmp实现rtmp，hls直播流

一、nginx+rtmp服务搭建

    下载nginx源码包：

wget https://mirrors.huaweicloud.com/nginx/nginx-1.14.0.tar.gz
           

解压缩：      

tar -xvzf ./nginx-1.14.0.tar.gz
           

    下载nginx-rtmp源码包：

wget https://github.com/arut/nginx-rtmp-module/archive/v1.2.1.tar.gz
           

解压缩： 

tar -xvzf ./v1.2.1.tar.gz
           

 安装nginx+rtmp组件

     nginx (1.3.14 - 1.5.0)版本运行如下命令：

./configure --add-module=/path/to/nginx-rtmp-module --with-http_ssl_module
           

make
  make install
           

二、服务配置

1、rtmp点播：

nginx.conf配置文件中，添加rtmp，与http平行：

rtmp{ server { listen 1996; #//服务端口 chunk_size 4096; #//数据传输块的大小 application vod { play /disk1/guoyiman/rtmp/test; #//视频文件存放位置。 } } } //播放url：rtmp://host:port/vod/videoname

2、rtmp直播：

events { use epoll;# 选择epoll模型可以达到最佳的IO性能 worker_connections 1024; } rtmp { #RTMP服务 server { listen 1996; #//服务端口 chunk_size 4096; #//数据传输块的大小 application live{ #直播 live on; } } }

rtmp直播推流，拉流播放操作：

使用ffmpeg推流: ffmpeg -re -i "jin_all.mp4" -f flv rtmp://10.200.20.56:1996/hls/flv 播放url： rtmp://10.200.20.56:1996/hls/flv

3、hls

RTMP推流请求配置

rtmp { server { # 监听端口 listen 1996; chunk_size 2048; application hls { live on; hls on; hls_path /data/hls; //hls 文件存放地址 } } }

HTTP播放配置

http{ ... server { listen 18880; server_name localhost; location / { root html; index index.html index.htm; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # http播放地址 location /hls { types { application/vnd.apple.mpegurl m3u8; video/mp2t ts; } root /data; //hls文件路径 add_header Cache-Control no-cache; } # 统计 location /stat { rtmp_stat all; rtmp_stat_stylesheet stat.xsl; } location /stat.xsl { root /disk1/guoyiman/rtmp/nginx-rtmp-module/; } } }

直播推流，hls播放

ffmpeg推流： ffmpeg -re -i "jin_all.mp4" -vcodec libx264 -vprofile baseline -f flv rtmp://10.200.20.56:1996/hls/test1 推流地址：rtmp://10.200.20.56:1996/hls，test1为名称可更改，hls为rtmp 中application 配置名称 rtmp播放：rtmp://10.200.20.56:1996/hls/test1 hls播放：http://10.200.20.56:18880/hls/test1.m3u8 监控统计：访问url：http://10.200.20.56:18880/stat

遇到的坑点：

1、配置hls_path路径，使用ffmpeg推流，rtmp直播流可访问，hls直播404，检查原因，hls_path路径下没有ts，m3u8文件；

2、视频流切片存放失败原因：使用nginx配置中没有给nginx指定用户名只能走默认的nobody用户和nogroup用户组，其实就是没有组，需要对写入的目录增大权限的修改

3、修改目录权限仍没有出现ts，m3u8文件，原因：目录权限指全路径而非某一文件夹，所有hls_path中全路径都需要增大权限，避免权限增大影响，在主目录下单独开出data目录增大权限，测试后删除文件夹；亦可对nginx指定高权限用户组，暂未尝试
