篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Linux开发_CentOS7.4服务器安装NFSNGINX服务器，ffmpegQt环境相关的知识，希望对你有一定的参考价值。
1. 环境介绍
环境介绍：采用的是华为云的ECS弹性云服务器–镜像安装的CentOS7.4 64位 -----是服务器版，非桌面版哦。
在CentOS7.4服务器版本的环境下搭建NFS服务器、安装ffmpeg、安装nginx服务器、部署Qt编译环境。
（1）配置NGINX为HTTP服务器，安装rtmp模块，完成rtmp视频推流，支持缓存视频到本地目录、支持转为HLS流，通过浏览器访问直播流。
（2）部署Qt编译环境，可以编译Qt代码，运行Qt程序。 因为是服务器，我这里部署Qt环境，运行Qt程序是属于控制台版本，不用Qt的GUI模块，只是用核心模块完成一些功能设计。
（3）安装、编译 ffmpeg ： 支持源码编译安装ffmpeg、在线安装ffmpeg，通过ffmpeg可以完成音视频的一些开发。比如：视频转码、视频合并、视频剪切、视频特效处理。----这里用ffmpeg并不是做播放器，是在服务器上用，主要是处理视频文件。
（4）安装NFS服务器，主要是方便与本地Linux系统进行通信，编译代码，文件共享。
（5）部署开机自动启动程序：方便设置自己的程序为开机启动。
2. 部署NFS服务器
注意：在云服务器上搭建NFS服务器，需要在控制台开放端口，不然NFS的端口无法正常访问，会被拦截。
2.1 安装NFS
