Centos6.5 nginx+nginx-rtmp配置流媒體服務器

之前使用命令方式安裝nginx並配置了反向代理，由於想做一個視頻直播的小項目，查了流媒體服務器的方案，發現nginx有相關模塊，於是開始搞起。

nginx-rtmp模塊需要在nginx編譯時，以模塊方式編譯進去，所以，之前搭建的nginx不能用了，只能另外下源碼編譯，但是也不必卸載原來的環境，后面會介紹如何處理兩個環境共存問題。

1.安裝編譯工具及庫文件（使用yum命令安裝）

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.源碼下載

nginx源碼

nginx-rtmp源碼

3.解壓源碼

4.編譯安裝

cd nginx-1.10.2

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

5.環境配置

首先要做的(如果之前配置過nginx，比如反向代理)，就是stop當前正在運行的nginx，並關閉開機自啟動

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

之后流媒體服務器（點播、直播）的配置，參考http://lib.csdn.net/article/57/37915?knId=1549，不再重復造輪子

注意：點播支持flv、mp4 視頻h264音頻aac格式

6.ffmpeg測試命令

推流

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

轉碼

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

 7.開機自啟

./usr/local/nginx/sbin/nginx

 

重點來了

在此視頻直播的基礎上，繼續配置nginx反向代理

主要修改nginx.conf就可以實現，這里有個問題，就是配置rtmp時，使用了http服務器的部分，相當於主域名www會由配置流媒體服務器的那個http server響應。原來nginx只是作為反向代理，自己不提供內容。這樣原來由apache響應的index就要交給nginx。

直接看配置吧

還有就是，之前www、blog、bbs都設置了cdn，在做了新域名解析后，網站靜態頁面的內容並沒有立即更新，這個把我坑了一把，等一段時間就好了，這和你設置cdn更新時間有關。還有就是，rtmp關心的是rtmp服務器的真實ip，如果域名做了cdn解析，可能會失敗。
