部署RTMP（nginx）视频流服务
利用 Root 用户进行配置: 切换 root 用户
sudo（superuser do或 switch user do，用于提权）
格式：sudo -u USERNAME COMMAND
sudo -i
su（switch user 或 substitute，用于切换用户）
格式：su -l USERNAME（-l为login，即登陆的简写）
-l 可以将l省略掉，所以此命令常写为su - USERNAME
三种方式切换到root的命令:su，su -和su - root
su -l 切换到 /etc 目次，创建并切换 rtmpServer 文件夹 cd /etc
mkdir rtmpServer
chmod 777 rtmpServer#(修改文件夹权限)
cd rtmpServer
将nginx-rtmp-module和nginx下载到该文件夹下。

Nginx
Nginx HTTP服务器,是用于 Web 服务、反向署理、内容缓存、负载均衡、媒体传播输等场景的开源软件。 这个流媒体服务器
安装 Nginx 1.8.1
下载地址 Nginx
利用 wget 下载
wget http://nginx.org/download/nginx-1.8.1.tar.gz
解压 nginx
tar -zxvf nginx-1.8.1.tar.gz
安装nginx的依靠库（可能存在环境变量版本等题目）
sudo apt-get update
sudo apt-get install libpcre3 libpcre3-dev
sudo apt-get install openssl libssl-dev
Nginx-rtmp-module
nginx-rtmp-module Nginx 一个nginx的流媒体服务器模块，可以支持RTMP和HLS(Live Http Stream)。
下载 nginx-rtmp-module
git clone https://github.com/arut/nginx-rtmp-module.git
https://i-blog.csdnimg.cn/direct/c0e90e2ac96a41d4b17afa096b9a3d90.png
配置并编译nginx
进入到nginx-1.8.1安装目次， 进入nginx源码目次，修改configure配置文件
添加nginx的rtmp模块。 add-module为下载的nginx-rtmp-module文件路径。
cd nginx-1.8.1
*[注释]:
修改配置

运行测试nginx
进入安装目次/usr/local/nginx，运行下令./sbin/nginx
cd /usr/local/nginx
./sbin/nginx
打开欣赏器在地址栏输入：localhost。假如
