拉取CentOS镜像（这里我拉取得是CentOS 7.8.2003）

[root@VM-0-8-centos /]# docker pull centos:7.8.2003
Using default tag: latest
latest: Pulling from library/centos
3c72a8ed6814: Pull complete

Status: Downloaded newer image for centos:latest

启动CentOS 7.8.2003镜像容器

[root@VM-0-8-centos /]# docker run -it -d -p 11935:1935 -p 180:80 -p 1443:443 centos:7.8.2003 bash

查看运行中容器并进入

[root@VM-0-8-centos /]# docker ps

[root@VM-0-8-centos /]# docker exec -it 34091d225d00 bash

查看系统版本

[root@34091d225d00 /]# cat /etc/redhat-release
CentOS Linux release 7.8.2003 (Core)

停止Docker容器

docker stop [CONTAINER ID]

安装ffmpeg

注： 此 ffmpeg 安装方式适用于CentOS 7

参考：CentOS中yum安装ffmpeg

准备环境

安装EPEL Release，因为安装需要使用其他的repo源，所以需要EPEL支持:

[root@34091d225d00 nginx-rtmp-ffmpeg]# yum install -y epel-release
