Ubuntu 16.04简易安装Nginx-rtmp-module

libnginx-mod-rtmp是18.04上自带的，可以通过apt-get install libnginx-mod-rtmp进行安装，在16.04上如果想要安装，直接下载libnginx-mod-rtmp_1.14.0-0+xenial1_amd64.deb安装的话会被告知nginx版本过低，依赖有问题，需要16.04自带的nginx版本是1.10，rtmp需要1.14。而一些其他文章都是需要编译nginx和nginx-rtmp-module来实现的安装。而我并不想上来就编译。找到了升级nginx的方法，将nginx升级后即可apt-get install libnginx-mod-rtmp安装libnginx-mod-rtmp了。

升级nginx到1.14

依次运行如下命令：

sudo apt-get install software-properties-common python-software-properties
sudo add-apt-repository ppa:nginx/stable
sudo apt-get update
sudo apt-get install nginx

这样就成功在Ubuntu 16.04上安装了libnginx-mod-rtmp。

测试

打开/etc/nginx/nginx.conf添加如下配置

rtmp {
    server {
        listen 1935;
        chunk_size 4096;
        application live {
            live on;
        }
    }
}

然后先重启

sudo systemctl restart nginx

开启推流端

ffmpeg -i test.mp4 -codec copy -f flv rtmp://localhost/live

开启拉流端

ffplay "rtmp://localhost/live live=1"

其他注意事项

如果是在阿里云或者腾讯云上安装，还要在安全组里打开1935端口。
