Centos6.5 nginx+nginx-rtmp配置流媒体服务器

之前使用命令方式安装nginx并配置了反向代理，由于想做一个视频直播的小项目，查了流媒体服务器的方案，发现nginx有相关模块，于是开始搞起。

nginx-rtmp模块需要在nginx编译时，以模块方式编译进去，所以，之前搭建的nginx不能用了，只能另外下源码编译，但是也不必卸载原来的环境，后面会介绍如何处理两个环境共存问题。

1.安装编译工具及库文件（使用yum命令安装）

yum install -y apr* autoconf automake bison bzip2 bzip2* cloog-ppl compat* cpp curl curl-devel fontconfig fontconfig-devel freetype freetype* freetype-devel gcc gcc-c++ gtk+-devel gd gettext gettext-devel glibc kernel kernel-headers keyutils keyutils-libs-devel krb5-devel libcom_err-devel libpng libpng* libpng-devel libjpeg* libsepol-devel libselinux-devel libstdc++-devel libtool* libgomp libxml2 libxml2-devel libXpm* libX* libtiff libtiff* make mpfr ncurses* ntp openssl nasm nasm* openssl-devel patch pcre-devel perl php-common php-gd policycoreutils ppl telnet t1lib t1lib* wget zlib-devel libxml2 libxml2-devel libxslt libxslt-devel unzip

2.源码下载

nginx源码

nginx-rtmp源码

3.解压源码

4.编译安装

cd nginx-1.10.2

./configure --add-module=../nginx-rtmp-module-master
make
sudo make install

5.环境配置

首先要做的(如果之前配置过nginx，比如反向代理)，就是stop当前正在运行的nginx，并关闭开机自启动

/etc/init.d/nginx stop
chkconfig --level 2345 nginx off

之后流媒体服务器（点播、直播）的配置，参考http://lib.csdn.net/article/57/37915?knId=1549，不再重复造轮子

注意：点播支持flv、mp4 视频h264音频aac格式

6.ffmpeg测试命令

推流

ffmpeg -re -i test.avi -vcodec h264 -acodec aac -f flv rtmp://219.216.87.99/live/test1

转码

ffmpeg -i test.avi -acodec aac -vcodec h264 -f flv test.flv

 7.开机自启

./usr/local/nginx/sbin/nginx

 

重点来了

在此视频直播的基础上，继续配置nginx反向代理

主要修改nginx.conf就可以实现，这里有个问题，就是配置rtmp时，使用了http服务器的部分，相当于主域名www会由配置流媒体服务器的那个http server响应。原来nginx只是作为反向代理，自己不提供内容。这样原来由apache响应的index就要交给nginx。

直接看配置吧

还有就是，之前www、blog、bbs都设置了cdn，在做了新域名解析后，网站静态页面的内容并没有立即更新，这个把我坑了一把，等一段时间就好了，这和你设置cdn更新时间有关。还有就是，rtmp关心的是rtmp服务器的真实ip，如果域名做了cdn解析，可能会失败。
