Ubuntu安装nginx-http-flv，并获取统计信息

1、依赖安装

复制代码

sudo apt-get install build-essential
sudo apt-get install libpcre3 libpcre3-dev
sudo apt-get install libssl-dev
sudo apt-get install zlib1g
sudo apt-get install zlib1g-dev

2、源码下载

NGINX 的版本应该大于或者等于 1.2.6，与其他版本的兼容性未知。nginx下载地址：http://nginx.org/download/。nginx-http-flv使用最新版本就可以，这里使用的nginx版本是1.14.2。

复制代码

mkdir nginx
cd nginx
wget http://nginx.org/download/nginx-1.14.2.tar.gz
tar -zxvf  nginx-1.14.2.tar.gz
git clone https://github.com/winshining/nginx-http-flv-module.git

3、编译安装

复制代码

cd nginx-1.14.2
./configure --prefix=/usr/local/nginx --with-http_ssl_module --add-module=../nginx-http-flv-module
make -j
make install

4、修改配置文件

修改/usr/local/nginx/conf/nginx.conf添加rtmp服务：

复制代码

rtmp {
	server {
		listen 1935;
		chunk_size 4000;
		application rtmp-live {
			live on;
	   }  
	}

}

修改http服务：

复制代码

http {
    ...
    server {
        listen       80;
        ...
		#开启flv
		location /live {
			flv_live on;
			chunked_transfer_encoding on;
		}
		#获取统计信息
		location /stat {
			rtmp_stat all;

			# Use this stylesheet to view XML as web page
			# in browser
			rtmp_stat_format json;
		}
		#control
		location /control {
			rtmp_control all;
		}
		...
    }
}

5、启动

执行

复制代码

/usr/local/nginx/sbin/nginx

6、测试

复制代码

ffmpeg -re -i test.mp4 -vcodec copy -acodec copy -f flv rtmp://127.0.0.1:1935/rtmp-live/test

rtmp仅支持H264/AAC，如果媒体不是H264/AAC，请使用下面的命令

复制代码

ffmpeg -i test.mp4 -vcodec libx264 -acodec fdk-aac -f flv rtmp://127.0.0.1:1935/rtmp-live/test

使用VLC播放视频：

rtmp播放地址：rtmp://127.0.0.1:1935/rtmp-live/test

http-flv播放地址：http://127.0.0.1:80/live?app=rtmp-live&stream=test

7、获取rtmp服务器统计信息

复制代码

curl 127.0.0.1:80/stat

返回json格式的数据，记录了rtmp server的连接情况：

复制代码
