基于 docker 搭建简单的流媒体服务器

“教你基于 docker 搭建一个简单的 Nginx-rtmp 流媒体服务器”

前言

由于本人昨天把系统给换了然后目前正在做的一个业余项目需要牵扯到流媒体服务器，但是之前系统环境是 ubuntu，现在给换成 Arch 了，而 Arch 软件更新比较激进，所以会导致 nginx 一些第三方模块编译出问题。而我个人也懒得折腾了，就想到干脆用 docker 得了。

正文

这里只教你怎么做，如果想知道为什么这么做，请找资料 (3j4wf4) 好好学习一下。

首先安装 docker ，没有安装的话点击这里

安装完 docker 之后请安装 ffmpeg，因为等下需要用到 ffmpeg 进行推流（实际开发中有很多第三方的 SKD 比如七牛云、网易、腾讯等等）。安装教程自己谷歌。

接下来新建一个文件夹，然后里面创建三个文件：Dockerfile、nginx.conf、sources.list

Dockerfile：

FROM ubuntu

构建 docker 镜像

docker build -t nginx:hls .

运行镜像

docker run -p9037:80 -p 1935:1935 -v /var/log/nginx:/usr/local/nginx/logs -v 用户流媒体文件目录:/usr/local/nginx/html/play -v 用户流媒体保存目录:/usr/local/nginx/html/video -v 用户音乐文件目录:/usr/local/nginx/html/music -d 镜像 id

参数解释：
-p：指定容器暴露的端口用户主机 IP:容器 IP -v：给容器挂载存储卷，挂载到容器的某个目录。通俗点就是共享文件夹主机目录:容器目录 -d：指定容器运行于前台还是后台
