环境：ubuntu 14

需要安装：nginx和ffmpeg

ffmpeg:

直接安装apt不行，需要添加源：

但是这是在线安装，只有可执行文件，不能开发！！

add-apt-repository ppa:kirillshkrogalev/ffmpeg-next
apt-get update
apt-get install ffmpeg

因为目前没涉及开发，未尝试源码安装。

nginx:

首先，nginx不支持动态安装插件，一定不要直接apt-get。

先安装nginx-rtmp-module插件，再安装配置时指定添加nginx-rtmp-module模块

git clone https://github.com/arut/nginx-rtmp-module.git 
wget http://nginx.org/download/nginx-1.8.0.tar.gz
tar -zxvf nginx-1.8.0.tar.gz
cd nginx-1.8.0
./configure --prefix=/usr/local/src/nginx  --add-module=../nginx-rtmp-module  --with-http_ssl_module
make
make install

这里遇到问题，却少一些依赖库，根据需要安装就行。

安装完后，打开本地127.0.0.1网页，即可查看是否安装成功。

两者都安装完毕，在nginx的配置模块添加配置，支持hls：

打开在nginx目录的conf目录下的nginx.conf文件，在末尾添加如下：

rtmp {  
    server {  
        listen 1935;  #监听的端口
        chunk_size 4000;  
        
        application hls {  #rtmp推流请求路径
            live on;
            hls on;
            hls_path /home/hls/test;
            hls_fragment 3s;
            record off;
        }  
    }  
}

再在开始server结构中添加如下：

location /hls{
	    types{
                 application/vnd.apple.mpegurl m3u8; 
                 video/mp2t ts;
	    }
	    alias /home/hls/test/;
	    expires -1;
	    add_header Cache-Control no-cache;
        }

为了最终测试，最好再加一个跨域策略，让其他ip也可以访问搭建的服务器。

location / {
            root   html;
            index  index.html index.htm;
            add_header Access-Control-Allow-Origin *;
            add_header Access-Control-Allow-Headers "Origin, X-Requested-With, Content-Type, Accept";
            add_header Access-Control-Allow-Methods "GET, POST, OPTIONS";
        }

最终nginx.conf配置文件如下：


#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

    worker_connections  1024;
}

    default_type  application/octet-stream;

    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
            add_header Access-Control-Allow-Origin *;
            add_header Access-Control-Allow-Headers "Origin, X-Requested-With, Content-Type, Accept";
            add_header Access-Control-Allow-Methods "GET, POST, OPTIONS";
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #

	location /hls{
	    types{
                 application/vnd.apple.mpegurl m3u8; 
                 video/mp2t ts;
	    }
	    alias /home/hls/test/;
	    expires -1;
	    add_header Cache-Control no-cache;
        }
    }


    # another virtual host using mix of IP-, name-, and port-based configuration

    #    location / {

    #    }
    #}

    #    location / {

    #        index  index.html index.htm;
    #    }
    #}

}

rtmp {  
    server {  
        listen 1935;  #监听的端口
        chunk_size 4000;  
        
        application hls {  #rtmp推流请求路径
            live on;
            hls on;
            hls_path /home/hls/test;
            hls_fragment 3s;
            record off;
        }  
    }  
}

而后保存，重启nginx，看是否报错。

./nginx reload #重新加载配置项

./nginx reopen #重新启动nginx

无错则进入下一步：

使用ffmpeg分片：

ffmpeg 转换mp4或aac为 hls

转换成的hls，直接放置在nginx目录下的html里面，这时候在浏览器打开响应的m3u8文件就可以播放了
