前言：由于前段时间刚租了台服务器打算自己玩玩，随想首页或者哪哪个页面挂个我个人的直播间应该还挺有趣的。遂探索如何在我的网站上弄一个直播。三下五除二，清清爽爽，看完此文5分钟即可直播。
整体思路
最简单直观的图解。
由上图，按步骤来说，我们只需要把流媒体服务器搭出来，直播就成一半了，流媒体服务器作为中间的载体至关重要。至于在前端播放rtmp流，有太多的轮子，这里就采用知名的video.js 。就不细说了。
安装nginx
选择 nginx 1.7.11.3 Gryphon.zip
http://nginx-win.ecsds.eu/download/
解压该包作为nginx的目录
安装rtmp模块
https://github.com/arut/nginx-rtmp-module/archive/master.zip
解压至nginx根目录下
解压后更将文件名从 nginx-rtmp-module-master 更改为 nginx-rtmp-module
编辑配置文件
默认的配置文件的最底部添加 rtmp 流媒体服务器的相关配置
#user nobody;
# multiple workers works !
worker_processes 2;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 8192;
# max value 32768, nginx recycling connections+registry optimization =
# this.value * 20 = max concurrent connections currently tested with one worker
# C1000K should be possible depending there is enough ram/cpu power
# multi_accept on;
}

# redirect server error pages to the static page /50x.html

error_page 500 502 503 504 /50x.html;
location = /50x.html {

}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80

# location / {

# }
#}
}
rtmp {
server {
listen 1935;
chunk_size 4000;
application live {
live on;
}
}
}
接着 启动nginx 此时 本机上的 rtmp://localhost:1935/live 的路径已被作为流媒体服务器处理了
使用直播软件推流
直播软件可选择的余地很多，这里使用开源的软件OBS
https://obsproject.com/zh-cn/
这里使用的是OBS-Studio-28.1.2
服务器那只需要将本机的ip地址填上就行了。

前端播放rtmp流
videojs 播放rtmp流，随便搜搜都是文章。
有一点需要注意的是：
video 6.0及以上版本，需要引入videojs-flash库（5.0及以下版本，flash在其核心库中，高版本分离了flash）
其余事项
在使用软件测试该流时 请记得将 1935 端口放行，当然以此类推，如果你将其放在任意的端口 应该在你的云服务器上将该端口放行以便外部访问。
