利用nginx和VLC&FLV自建直播服务器并实现播放

服务器环境：Centos

nginx-rtmp-module项目地址：https://github.com/arut/nginx-rtmp-module

方法参考：https://www.nginx.org.cn/article/detail/259

此方法需要使用nginx插件，通过对nginx本体的编译安装实现。

编译安装命令

./configure --user=nginx --group=nginx 
--prefix=/home/nginx-rtmp/rtmp --add-module=/home/nginx-rtmp/nginx-rtmp-module-1.2.2 \
make && make install

注释：

--add-module=/home/nginx-rtmp/nginx-rtmp-module-1.2.2 是选择此项目编译入NGINX程序

服务端配置文件：

worker_processes  1;

events {
    worker_connections  1024;
}

rtmp {
    server {
        listen 1935;
        chunk_size 4096;

        application vod {
                play /opt/video/vod;
        }

        application live{ #第一处添加的直播字段
                live on;
        }
    }

}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;

        location /stat {     #第二处添加的location字段。
            rtmp_stat all;
            rtmp_stat_stylesheet  html/stat.xsl;
        }

        location /stat.xsl { #第二处添加的location字段。
                root /home/nginx-rtmp/rtmp;
        }

        location / {
            root   html;
            index  index.html index.htm;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}

在访问http://127.0.0.1/stat统计页面时，如果出现stat.xsl报错404，则需要加入以下文件在html/html路径
