利用Nginx搭建http和rtmp协议的流媒体服务器

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

include ld.so.conf.d/*.conf 
/lib 
/lib64 
/usr/lib 
/usr/lib64 
/usr/local/lib 
/usr/local/lib64 
/opt/ffmpeg/lib 
#ldconfig 
二、安装Nginx相关模块 
#tar zxvf nginx_mod_h264_streaming-2.2.7.tar.gz 
#git clone git://github.com/arut/nginx-rtmp-module.git 
#tar zxvf pcre-8.12.tar.gz 
#cd pcre-8.12 
#./configure 
#make && make install 
#tar zxvf nginx-1.2.6.tar.gz 
#cd nginx-1.2.6 
#./configure –prefix=/usr/local/nginx –add-module=../nginx_mod_h264_streaming-2.2.7 –with-http_flv_module –with-http_gzip_static_module –with-http_stub_status_module –with-http_mp4_module –add-module=../nginx-rtmp-module –add-module=../nginx-rtmp-module/hls –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://192.168.0.33:8080/stats 查看rtmp客户请求信息 
http://192.168.0.33:8081/index.html 查看nginx http协议时候的flv视频 
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) 
 
 
 
 
test of nginx-http 
 
 

 
 
 
 
 
 
 
ndex.cgi?P1_Prod_Version=ShockwaveFlash” flashvars=”type=http&file=http://192.168.0.33:8081/2.flv&autostart=true” wmode=”opaq 
ue” /> 
 
 
 
NGINX-RTMP测试页面index.html

 
 
 
 
nginx-rtmp 

 

 
 
 
 
 
 
 
ndex.cgi?P1_Prod_Version=ShockwaveFlash” flashvars=”streamer=rtmp://192.168.0.33:1935/vod&file=2.flv&autostart=true” wmode=”o 
paque” /> 
 
 

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。
