1.先添加几个RPM下载源
2.安装转码工具Mencoder及ffmpeg(约定：每个小点操作之前先回到用户主目录，即cd ~)
3.4)各种配置nginx
编辑/usr/local/nginx/conf/nginx.conf文件，最好用sftp软件(如windows下的flashfxp/Mac下的tramnsmit)下载过来本地编辑。
贴一下我的配置文件:(目录需要自己改动，我用的是阿里云的数据盘，所以到/mnt/里面去了)

# HLS
# HLS requires libavformat & should be configured as a separate
# NGINX module in addition to nginx-rtmp-module:
# ./configure … –add-module=/path/to/nginx-rtmp-module/hls …
# For HLS to work please create a directory in tmpfs (/tmp/app here)
# for the fragments. The directory contents is served via HTTP (see
# http{} section in config)
#
# Incoming stream must be in H264/AAC/MP3. For iPhones use baseline H264
# profile (see ffmpeg example).
# This example creates RTMP stream from movie ready for HLS:
#
# ffmpeg -loglevel verbose -re -i movie.avi -vcodec libx264
# -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1
# -f flv rtmp://localhost:1935/hls/movie
#
# If you need to transcode live stream use ‘exec’ feature.

4.把自己的电影转换成mp4和flv格式来测试nginx搭的环境
4.1)准备两部电影，硬盘上随便找，我找了“谍影重重A.mp4”和“鹿鼎记033.rmvb”，尽量找小一点十来分钟的，等下我们还要看完测试一下转换的结果有没有音影不同步的情况。
我把两部电影重命名为 movie1.mp4和 movie2.rmvb，并上传到服务器/mnt/media/video下面，这里目录用来存放我们的原始视频。还有一个目录是/mnt/media/vod 用来存放转换后的视频。
我这里的具体目录结构为:
/mnt/media/video -> 存放原始视频
/mnt/media/app -> 存放转成m3u8的视频,供http访问(HLS)
/mnt/media/vod -> 存放转换后的flv和mp4视频,供http或rtmp访问
注：安装日志记录于半年前的evernote，现在才贴出来的，所以文中的视频访问地址都已经失效了。
