本文举个简单的例子, 关于使用nginx搭建流媒体服务.
nginx的安装参考 :
我们把流媒体文件放到/media目录, 放3个测试文件, 分别包含了avi, flv, mov格式.
另外还需要一个WEB播放器, 使用jwplayer.swf.
[root@dba conf]# cd /media/
[root@dba media]# ll
total 110330
-rw-r--r-- 1 root root 42032120 Dec 22 2013 1.avi
-rw-r--r-- 1 root root 16776688 Oct 30 2013 img_0256.mov
-rw-r--r-- 1 root root 54213271 Oct 30 2013 mayun.flv
-rw-r--r-- 1 root root 91042 Jun 7 2010 player.swf
和flv,mov,avi文件结束相关的location 配置, nginx.conf :
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
server {
listen 0.0.0.0:80;
server_name dba.sky-mobi.com default_server;
location ~ \.flv$ {
limit_rate_after 5M; # 下载5M后开始限速.
limit_rate 1M; # 限速1M/s.
root /media;
flv;
}
location ~ \.swf$|\.mov$|\.avi$ {
limit_rate_after 5M;
limit_rate 1M;
root /media;
}
}
}
[root@dba media]# cd /opt/nginx1.6.0/conf/
[root@dba conf]# cat mime.types

flv和mov效果比较好, 支持拖动播放. avi需要windows media解码.
输入以下URL, 自动打开flash player, 播放相应的文件 :
http://dba.sky-mobi.com/player.swf?file=mayun.flv
http://dba.sky-mobi.com/player.swf?file=1.avi
http://dba.sky-mobi.com/player.swf?file=img_0256.mov
如果直接输入以下URL的话会变成下载文件.
http://dba.sky-mobi.com/mayun.flv
http://dba.sky-mobi.com/1.avi
http://dba.sky-mobi.com/img_0256.mov
