docker 搭建nginx-rtmp

拉取镜像

首先,在docker的镜像页面 https://hub.docker.com/search?type=image 搜索关键词 “nginx rtmp” 1 2

sudo docker pull alqutami/rtmp-hls

3

镜像说明(alqutami/rtmp-hls)

  1. 这是一个基于 Nginx 和 nginx-rtmp-module 的模块
  2. 使用 FFmpeg 来转码和自适应流媒体
  3. 默认配置
  1. 统计页面 http://:/stats
  2. 基于video.jshls.js的web视频播放器,被放在 /usr/local/nginx/html/players 下面.

该镜像使用如下模块编译

  1. Nginx 1.17.5
  2. Nginx-rtmp-module 1.2.1
  3. FFmpeg 4.2.1

使用方式

启动服务

sudo docker run -d -p 1935:1935 -p 8080:8080 alqutami/rtmp-hls
  1. 使用 docker run <镜像名> 启动镜像
  2. -d 指示容器在后台运行
  3. -p 用来设置端口映射(主机端口 : 容器端口)

使用自定义的配置文件启动容器

sudo docker run -d --name rtmp -p 1935:1935 -p 8080:8080 -v ~/Documents/nginx-1.19.2/conf/nginx.conf:/etc/nginx/nginx.conf alqutami/rtmp-hls
  1. --name 用来指定容器名称(不指定会自动赋予一个随机名)
  2. -v用于挂载宿主机的目录。前面是本地目录,后面是挂载到容器中的目录

4

镜像的配置文件 nginx.confGithub 上,可以参考着改 https://github.com/TareqAlqutami/rtmp-hls-server/blob/master/conf/nginx.conf

5

推送流

RTMP的实时流可以推送到如下地址

rtmp://<server ip>:1935/live/<stream_key>

其中 stream_key 可以是你指定的任何关键字

查看流

https://github.com/TareqAlqutami/rtmp-hls-server/blob/master/players/rtmp.html 6

实战

查看本机ip

  1. 局域网 ifconfig | grep "inet 192" 7

  2. 云服务器 curl ip.sb 7

启动容器

  1. 默认方式

docker run 的时候,不用特意去 pull 镜像,如果发现没镜像会自动下载

sudo docker run -d -p 8080:8080 -p 1935:1935 alqutami/rtmp-hls
  1. 自定义配置文件

如果需要自定义配置文件,可以自己写 nginx.conf,在启动容器时进行挂载

docker run -d -p 1935:1935 -p 8080:8080 -v custom.conf:/etc/nginx/nginx.conf alqutami/rtmp-hls

此外,也可以去镜像 Github 拷贝修改,Github 地址 https://github.com/TareqAlqutami/rtmp-hls-server/tree/master/conf

    	location /stat.xsl {
    		# XML stylesheet to view RTMP stats.
    		root /usr/local/nginx/html;
    	}
    }
}

但是上面这个配置文件是有误的,你会发现如果自己再外挂一些静态网站上去,外链的css、js等资源无效了。需要修改nginx.conf,在html节点上添加一段

http {
    include       mime.types;
	default_type  application/octet-stream;
	……
}
  1. 更换映射端口

有的时候,主机(或云服务器)的80、8080、1935等常用端口都被占用了。 这时候就得更换映射端口了,语法为-p <宿主机端口>:<容器端口>

sudo docker run -d -p 18080:8080 -p 11935:1935 alqutami/rtmp-hls
  1. 配置静态网页

配置静态网页和自定义配置文件的方法一样,都是通过挂载实现的。唯一的区别是自定义配置文件挂载的是单个文件,而自定义网页挂载的是整个目录。另外/usr/local/nginx/html是静态html文件的挂载目录,但其下有文件,因此我们只能挂载到它的子目录

docker run -d -p 1935:1935 -p 8080:8080 -v custom.conf:/etc/nginx/nginx.conf -v ~/mynginx/customhtml:/usr/local/nginx/html/test alqutami/rtmp-hls

推流

rtmp协议的默认端口是1935,如果启动容器的时候替换成了别的端口,需要在rtmp的地址后面跟上端口,除此之外,其他都一样。

ffmpeg -re -stream_loop -1 -i /home/chen/Desktop/QQ视频20200524211316.mp4 -vcodec copy -acodec copy -f flv -y rtmp://127.0.0.1/live/test
