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
模块:nginx-rtmp-module支持rtmp //2015-3-5 add

#cd git-2013-02-04
#autoconf
#./configure
#make && make install
# git –version
git version 1.8.1.GIT
#cd ..
3、安装ffmpeg及其依赖包：

修改/etc/ld.so.conf如下:
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)
-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>

NGINX-RTMP测试页面index.html
-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>

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。
