主题 RTMP Nginx HTTP

实验目的:让Nginx支持flv和mp4格式文件，同时支持Rtmp协议；同时打开rtmp的hls功能

资料: 

HTTP Live Streaming（缩写是 HLS）是一个由苹果公司提出的基于HTTP的流媒体 网络传输协议。 

HLS只请求基本的HTTP报文，与实时传输协议（RTP)不同，HLS可以穿过任何允许HTTP数据通过的防火墙或者代理服务器。它也很容易使用内容分发网络来传输媒体流。 

使用ffmpeg来完成对flv、mp4、mp3等格式的转化（点播实验暂时不测试）

一、准备工作 

模块:nginx_mod_h264_streaming(支持h264编码的视频) 

模块:http_flv_module 支持flv 

模块:http_mp4_module 支持mp4

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

#tar zxvf pcre-8.12.tar.gz 

#cd pcre-8.12

–with-cc-opt=-I/opt/ffmpeg/include –with-ld-opt=’-L/opt/ffmpeg/lib -Wl,-rpath=/opt/ffmpeg/lib’ 

#make && make install

三、修改nginx主配置文件,配置虚拟主机(这里我们暂时只配置和测试点播，直播请看借鉴地址): 

user nobody nobody; 

worker_processes 4; 

error_log logs/nginx_error.log info; 

pid logs/nginx.pid; 

worker_rlimit_nofile 51200; 

events 

{ 

use epoll; 

worker_connections 51200; 

} 

#rtmp_auto_push on; 

rtmp { 

server { 

listen 1935; 

application vod { 

play /opt/media/nginxrtmp/flv; 

} 

} 

} 

http 

{ 

include mime.types; 

default_type application/octet-stream; 

server_names_hash_bucket_size 128; 

client_header_buffer_size 32k; 

large_client_header_buffers 4 32k; 

client_max_body_size 50m ; 

limit_conn_zone $binary_remote_addr zone=perip:256k; 

limit_conn_log_level notice; 

sendfile on; 

tcp_nopush on; 

keepalive_timeout 6000;#测试并发临时调大 

tcp_nodelay on; 

gzip on; 

gzip_min_length 1k; 

gzip_buffers 4 16k; 

gzip_http_version 1.0; 

gzip_comp_level 2; 

gzip_types text/plain application/x-javascript text/css application/xml; 

gzip_vary on; 

#log format 

log_format main ‘$remote_addr – $remote_user [$time_local] “$request” ‘ 

‘$status $body_bytes_sent “$http_referer” ‘ 

‘”$http_user_agent” $http_x_forwarded_for’;

#支持flv 

server 

{ 

listen 8081; 

server_name 192.168.0.33; 

root /opt/pub/media/nginx; #http协议时候，flv视频位置 

location ~ .*.(flv|swf|mp4|wma|wmv)$ { 

valid_referers none blocked *.xxxx.com http://localhost; 
if ($invalid_referer) { 

return 403; 

} 

} 

location ~ \.flv$ { 

flv; 

limit_conn one 20;#限制客户端并发连接数 

limit_rate 200k;#限制每客户端最大带宽 

} 

location ~ \.mp4$ { 

flv; 

limit_conn one 20; 

limit_rate 200k; 

} 

access_log logs/nginxflv_access.log main; 

}

server 

{ 

listen 8082; 

server_name 192.168.0.33; 

index index.html; 

location / { 

root /opt/pub/media/nginx-rtmp; 

} 

access_log logs/nginxrtmpflv_access.log main; 

}

server { 

listen 8080; 

location /stat { 

rtmp_stat all; 

rtmp_stat_stylesheet stat.xsl; 

} 

location /stat.xsl { 

root /opt/pub/soft/nginx-rtmp-module; 

} 

location / { 

root /opt/pub/soft/nginx-rtmp-module/test/rtmp-publisher; 

} 

}

http://192.168.0.33:8082/index.html 查看nginx rtmp协议时候的flv视频 

四、基本功能测试: 

播放器采用开源播放器jwplayer，将播放器放到index.html同级目录下 

NGINX-Http测试页面index.html(切记http的时候需要给视频添加关键帧)

paque” /> 

</object> 

</body> 

</html>

页面能打开正常播放就说明配置是正确的。

五、并发测试

NGINX-HTTP采用loadrunner测试（略）

NGINX-RTMP采用开源软件flazr测试:

前提需要安装jdk软件

client.bat rtmp://192.168.0.33:1935/vod/2.flv -load 500

这里的500是并发数

由于局域网的限制，带宽测试到一定大小的时候就上不去了，故此步截图不忽略。
