nginx+obs搭建流媒体，实现直播 流媒体
1.直播是现在最热门的，尤其是电竞的发展成功的带动的直播的发展，各种游戏直播月入XXX，经常听到的一句话：某主播XXX月入百万，不知道是真是假暂且不管，看看直播到底是怎么实现的，直播使用的是RTMP协议（实时消息传输协议），实现这个协议的方式有很多种，这里使用nginx（一个超级强大的服务器）的rtmp-moudle模块来实现。我是在ubantu上面搭建的环境：
首先准备nginx安装包和nginx-rtmp-module模块的安装包
nginx安装包:http://nginx.org/,请自行下载
wget http://nginx.org/download/nginx-1.11.3.tar.gz
nginx-rtmp-module模块下载
wget https://github.com/arut/nginx-rtmp-module/archive/master.zip
下载完毕解压
tar -zxvf nginx-1.11.3.tar.gz
unzip master.zip(没有安装该软件包：sudo apt-get install unzip)
解压完毕进入nginx-1.11.3文件夹
./configure--add-module=../arut-nginx-rtmp-module-c0bf381
sudo make
sudo make install
安装完毕!
运行nginx：
sudo /usr/local/nginx/sbin/nginx
运行:ifconfig查看ubantu的ip地址：
打开浏览器输入:你本机的ip看到nginx的欢迎页面，说明安装成功，如图：
然后：
cd /usr/local/nginx/conf
nginx的配置文件可能没有修改的权限
修改权限：
sudo chmod 777conf/
编辑nginx.conf文件，我贴出整个配置文件：

[*] #}

[*] # deny access to .htaccess files, if Apache's document root

[*] #
[*] #location ~ /\.ht {

[*] server {

[*] chunk_size 4096;

[*] }
加的配置就在最后，复制添加即可。
保存之后重启nginx：
sudo /usr/local/nginx/sbin/nginx -s stop
sudo /usr/local/nginx/sbin/nginx
没有出现错误，这时已经成功搭建好了rtmp流媒体，这时需要一个推流的客户端给服务器
这里选择OBS，比较出名的一个软件：下载地址：
https://obsproject.com/download#mp
自己下载安装
安装完毕配置obs
注意IP要该为自己的。
完毕之后还有做一个浏览器的展示：
建立play.php
view plain copy

jwplayer包请在这里下载：http://download.csdn.net/detail/gaoxuaiguoyi/9300373
下载完毕直接放在目录下面就可以了：
访问:你的IP/play.php
到此实现的简单的直播。
