声明：网上有很多关于Linux系统的配置，这里就不记录了。刚开始搭建直播室，用的是Java语言，
Java开源的流媒体服务有Red5,但是很久没更新了，而且文档较少不容易上手，对于直播功能相对要求较低的还是选择ngin来搭建流媒体服务，下面是记录搭建步骤。
一、下载搭建时需要用到的软件
1、下载 nginx 1.7.11.3 Gryphon
链接: http://nginx-win.ecsds.eu/download/nginx 1.7.11.3 Gryphon.zip
下载完成后解压，将文件重新命名因为含有空格，nginx
2、下载服务器状态检查程序
链接：https://github.com/arut/nginx-rtmp-module/
下载完成后解压，将解压过的文件放到nginx根目录，例如：E:\nginx\nginx-rtmp-module
3、下载OBS推流软件
链接：https://obsproject.com/ 进入官网选择下载
二、配置流媒体服务
1、修改nginx服务器中 conf 目录下的 nginx-win.conf 文件，配置如下
#user nobody;
# multiple workers works !
worker_processes ; #error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info; #pid logs/nginx.pid; events {
worker_connections ;
# max value , nginx recycling connections+registry optimization =
# this.value * = max concurrent connections currently tested with one worker
# C1000K should be possible depending there is enough ram/cpu power
# multi_accept on;
} rtmp {
server {
listen 1935;
chunk_size 4000;
notify_method get;
application live { #rtmp推流地址：rtmp://ip地址:1935/live
live on;
on_publish http://192.168.8.210/on_publish.php; #rtmp推流鉴权,如果鉴权不通过则没有权限进行推流
}
}
} http {

#} }
推流鉴权文件PHP：on_publish.php，可以为任意服务端文件， on_publish 指定服务器鉴权地址,此代码简单的作了用户验证，也可以改成带数据库验证以及加入更多参数进行验证。
<?php // ?user=user&pass=pass $user = isset($_POST['user']) ? $_POST['user'] : '';
$pass = isset($_POST['pass']) ? $_POST['pass'] : ''; if (empty($user) || empty($pass)) {
echo "wrong query input";
header('HTTP/1.0 500 error...');
exit();
} $saveuser = $user;
$savepass = $pass; if (strcmp($user, $saveuser) == 0 && strcmp($pass, $savepass) == 0) {
echo "Username and Password OK";
} else {
echo "Username or Password wrong";
header('HTTP/1.0 404 Not Found');
exit();
} ?>
注意：在接受参数时一定用POST接收，否则鉴权失败。
更新配置文件，运行cmd命令：
> cd nginx
> nginx.exe -c conf\nginx-win.conf
2、打开OBS客户端进行推流测试，按照如下步骤进行配置
注意：rtmp地址：rtmp://ip地址:1935/live?user=1&pass=2，后面的参数为鉴权所用，否则连接失败。
