nginx实现最简单的直播

2018-11-04 分类:实用技能 阅读(1025) 评论(0)

关于直播技术的原理,这里我就不啰嗦了,可以参考文章https://blog.csdn.net/leifukes/article/details/73244012

 

我的环境

[root@controller ~]# cat /etc/redhat-release

CentOS Linux release 7.2.1511 (Core)

[root@controller ~]# getenforce

Disabled

[root@controller ~]# systemctl stop firewalld

[root@controller ~]# hostname -I

10.0.0.11

 

 

1:git拉取nginx-rtmp插件

mkdir -p /server/tools

cd /server/tools

git clone https://github.com/arut/nginx-rtmp-module.git

 

2:编译安装nginx

useradd -s /sbin/nologin -M nginx

wget http://nginx.org/download/nginx-1.14.0.tar.gz

tar xf nginx-1.14.0.tar.gz

ls

cd nginx-1.14.0/

yum install pcre-devel -y

yum install openssl-devel.x86_64 -y

./configure --user=nginx --group=nginx --with-http_ssl_module --prefix=/application/nginx --add-module=../nginx-rtmp-module

make

make install

 

 

3:配置启动nginx

cd /application/nginx/conf/

grep -Ev '^$|#' nginx.conf.default >nginx.conf

vim nginx.conf

worker_processes 1;

events {

worker_connections 1024;

}

rtmp {

server {

listen 1935;

chunk_size 4096;

application live {

     live on;

hls on;

hls_path /application/nginx/html/live;

hls_fragment 5s;

}

}

}

 

http {

include mime.types;

default_type application/octet-stream;

sendfile on;

keepalive_timeout 65;

server {

listen 80;

server_name localhost;

location /live {

types {

application/vnd.apple.mpegurl m3u8;

video/mp2t ts;

}

alias /application/nginx/html/live;

expires -1;

add_header Cache-Control no-cache;

}

location / {

root html;

index index.html index.htm;

}

}

}

 

#测试nginx语法

../sbin/nginx –t

启动nginx

../sbin/nginx

 

4:使用EV录屏实现推流

串流地址: rtmp://10.0.0.11:1935/live

地址密钥随便填,我这里是test

 

如果你的地址密钥填写和一样的话,

开启直播之后,测试能否下载test.m3u8文件

http://10.0.0.11/live/test.m3u8

如果能够成功下载,恭喜你离成功很近了!

 

5:配置站点首页

vi /application/nginx/html/index.html

<!DOCTYPE html>

<html lang="zh-CN">

<head>

<meta charset="UTF-8">

<title>前端播放m3u8格式视频</title>

<link rel="stylesheet" href="http://vjs.zencdn.net/5.5.3/video-js.css">

<script src="http://vjs.zencdn.net/5.5.3/video.js"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/videojs-contrib-hls/5.12.2/videojs-contrib-hls.js"></script>

</head>

<body>

<video id="myVideo" class="video-js vjs-default-skin vjs-big-play-centered" controls preload="auto" width="1080" height="708" data-setup='{}'>

<source id="source" src="http://10.0.0.11/live/test.m3u8" type="application/x-mpegURL">

</video>

</body>

<script>

// videojs 简单使用

var myVideo = videojs('myVideo',{

bigPlayButton : true,

textTrackDisplay : false,

posterImage: false,

errorDisplay : false,

})

myVideo.play() // 视频播放

myVideo.pause() // 视频暂停

</script>

</html>

 

打开浏览器测试:

http://10.0.0.11/

 

至此成功!!!
