前言
由于html中的video现在不支持rtmp协议(需要重写播放器框架，flash被一刀切，360浏览器还在支持flash),遂用rtmp作为桥梁,实际是hls协议在html中起作用. 在此推荐一款前端播放器,.ckplayer 简直了,写点页面,一直循环，洗脑神曲 dream it possible.
搭建nginx服务器
环境准备
1.下载环境
nginx包: nginx包 RTMP模块包:nginx-http-flv-module 模块包
2.依赖项
yum -y install unzip
yum -y install gcc-c++
yum -y install pcre pcre-devel
yum -y install zlib zlib-devel
yum -y install openssl openssl-devel3.安装
新建nginx路径
mkdir /usr/local/nginx将下载的模块包复制到nginx目录下，并解压
cp /opt/toos/nginx-http-flv-module-1.2.6.zip /usr/local/nginx/nginx-http-flv-module
cd /usr/local/nginx
unzip nginx-http-flv-module安装nginx服务器
tar -zxvf nginx-1.8.1.tar.gz
cd nginx-1.8.1
./configure --prefix=/usr/local/nginx --add-module=/usr/local/nginx/nginx-http-flv-module
