nginx搭建支持http和rtmp协议的流媒体服务器之---环境搭建

视频有两总发布方式

　1、HTTP方式

　　这种方式要下载FLV视频文件到本地播放，一旦FLV视频文件下载完成，就不会消耗服务器的资源和带宽，可是拖动功能没有RTMP/RTMP流媒体方式强大，不少视频网站都是用HTTP方式实现的，如：YouTube，土豆，酷6等

　2、RTMP/RTMP流媒体方式

　　这种方式不用下载FLV视频文件到本地，能够实时的播放flv文件，能够任意拖拽播放进度条，可是比较消耗服务器的资源

实验目的:
让Nginx支持flv和mp4格式文件，支持RTMP协议的直播和点播

准备工做
Nginx: http://nginx.org
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

一、安装依赖包:
#yum -y install gcc glibc glibc-devel make nasm pkgconfig lib-devel openssl-devel expat-devel gettext-devel libtool mhash.x86_64 perl-Digest-SHA1.x86_64

二、安装相关工具包
1). 安装git，之后后面一些程序须要安装下载须要用到git
# mkdir soft-source
# cd soft-source
# wget http://codemonkey.org.uk/projects/git-snapshots/git/git-latest.tar.xz
# xz -d git-latest.tar.xz
# tar xzvf git-latest.tar 

# cd git-2014-06-27

# autoconf
# ./configure
# make

若是make报错以下，执行：yum install perl-ExtUtils-Embed -y

#make install
# git --version   看到版本输出证实安装成功

# cd ..

2). zlib
# wget http://zlib.net/zlib-1.2.8.tar.gz
# tar -zxvf zlib-1.2.8.tar.gz cd zlib-1.2.8
# ./configure
# make
# make install
# cd ..

3). pcre
# wget http://exim.mirror.fr/pcre/pcre-8.12.tar.gz
# tar zxvf pcre-8.12.tar.gz
# cd pcre-8.12
# ./configure
# make

若是make过程出现了如下报错，请安装：yum -y install gcc gcc-c++,而后再从新执行./configure 再make

#make install

# cd ..

4). yadmi
yadmi的做用是为flv文件添加关键帧，才能实现拖动播放
# wget http://sourceforge.net/projects/yamdi/files/yamdi/1.4/yamdi-1.4.tar.gz/download  
# tar xzvf yamdi-1.4.tar.gz
# cd yamdi-1.4
# make && make install
# cd ..
 
使用方法：
# yamdi -i input.flv -o out.flv
给input.flv文件 添加关键帧，输出为out.flv文件

5). OpenSSL
# wget http://www.openssl.org/source/openssl-1.0.1c.tar.gz
# tar -zxvf openssl-1.0.1c.tar.gz
# ./config
# make
# make install

三、安装ffmpeg及其依赖包：
1). Yasm
# wget http://www.tortall.net/projects/yasm/releases/yasm-1.2.0.tar.gz
# tar xzvf yasm-1.2.0.tar.gz
# cd yasm-1.2.0
# ./configure
# make
# make install
# cd ..

2). x264
# git clone git://git.videolan.org/x264
# cd x264
# ./configure --enable-shared 
# make
# make install
# cd ..

3). LAME
# wget http://downloads.sourceforge.net/project/lame/lame/3.99/lame-3.99.5.tar.gz
# tar xzvf lame-3.99.5.tar.gz
# cd lame-3.99.5

#./configure --enable-nasm
# make
# make install
# cd ..

4). libogg
# wget http://downloads.xiph.org/releases/ogg/libogg-1.3.0.tar.gz
# tar xzvf libogg-1.3.0.tar.gz
# cd libogg-1.3.0
# ./configure
# make
# make install
# cd ..

5). libvorbis
# wget http://downloads.xiph.org/releases/vorbis/libvorbis-1.3.3.tar.gz
# tar xzvf libvorbis-1.3.3.tar.gz
# cd libvorbis-1.3.3
# ./configure
# make
# make install
# cd ..

6). libvpx
# git clone http://git.chromium.org/webm/libvpx.git
# cd libvpx
# ./configure  --enable-shared
# make
# make install
# cd ..

7). FAAD2
# wget http://downloads.sourceforge.net/project/faac/faad2-src/faad2-2.7/faad2-2.7.tar.gz
# tar zxvf faad2-2.7.tar.gz
# cd faad2-2.7
# ./configure
# make
# make install
# cd ..

8). FAAC
# wget http://downloads.sourceforge.net/project/faac/faac-src/faac-1.28/faac-1.28.tar.gz
# tar zxvf faac-1.28.tar.gz
# cd faac-1.28# ./configure
# make
# make install
# cd ..

9). Xvid
# wget http://downloads.xvid.org/downloads/xvidcore-1.3.2.tar.gz
# tar zxvf xvidcore-1.3.2.tar.gz
# cd xvidcore/build/generic
# ./configure
# make
# make install
# cd ..

10). ffmpeg
# git clone git://source.ffmpeg.org/ffmpeg
# cd ffmpeg
# ./configure  --prefix=/opt/ffmpeg/ --enable-version3  
--enable-libvpx --enable-libfaac --enable-libmp3lame  
--enable-libvorbis --enable-libx264 --enable-libxvid 
--enable-shared --enable-gpl --enable-postproc --enable-nonfree  
--enable-avfilter --enable-pthreads
# make && make install# cd ..

修改/etc/ld.so.conf以下:
include ld.so.conf.d/*.conf
/lib
/lib64
/usr/lib
/usr/lib64
/usr/local/lib
/usr/local/lib64
/opt/ffmpeg/lib
# ldconfig

2、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

2. 建立用户和组
# groupadd www
# useradd -g www www
3. nginx安装# wget http://nginx.org/download/nginx-1.6.0.tar.gz# tar zxvf nginx-1.6.0.tar.gz# cd nginx-1.6.0
