ubuntu下使用nginx搭建流媒体服务器，实现视频点播，ubuntunginx

首先我们看如何实现视频点播，视频点播支持flv文件及H264编码视频，ACC编码音频的mp4文件： 
第一步，创建单独的目录（因为软件较多，容易混乱），下载需要的软件: 
我们需要下载nginx，pcre，zlib，openssl以及nginx-rtmp-module

 1 mkdir work
 2 
 3 cd work
 4 
 5 wget http://nginx.org/download/nginx-1.10.3.tar.gz
 6 
 7 wget http://zlib.net/zlib-1.2.11.tar.gz
 8 
 9 wget https://ftp.pcre.org/pub/pcre/pcre-8.40.tar.gz
10 
11 wget https://www.openssl.org/source/openssl-1.0.2k.tar.gz
12 
13 wget https://github.com/arut/nginx-rtmp-module/archive/master.zip

 

第二步，分别解压这四个文件：

tar -zxvf 文件名

 

第三步，编译安装nginx：

./configure --prefix=/usr/local/nginx --with-debug --with-pcre=../pcre-8.40 --with-zlib=../zlib-1.2.11 --with-openssl=../openssl-1.0.2k --add-module=../nginx-rtmp-module-master

make

sudo make install

 

第四步，进入 /usr/local/nginx/conf，配置nginx.conf文件，在文件末尾添加如下内容：

rtmp {
    server {
        listen 1935;

        application vod {
            play /var/flvs; #指定存放视频文件的路径
        }

        application vod_http {
            #myserver.com及服务器地址，如果只是本地播放，填写127.0.0.1:端口号 就行，端口好看配置文件中http监听的端口下同
            play http://myserver.com/vod; 
        }

        application vod_mirror {
            play /var/local_mirror http://myserver.com/vod;
        }
    }
}

示例完整版：

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}

rtmp {
    server {
        listen 1935;

    application vod {
            play /video_test;
    }

    application vod_http {
            play http://192.168.1.102:8080/vod;
    }

    application vod_mirror {
            # try local location first, then access remote location
        play /var/local_mirror http://192.168.1.102:8080/vod;
    }
    }
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       8080;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

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

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

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


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

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

}

然后，进入与conf文件夹同级的sbin目录下，运行：

sudo ./nginx

至此，服务器搭建完成，可以实现视频点播了。 

视频点播测试： 
播放位于 /video_test 下的file.flv视频文件：

ffplay rtmp://localhost/vod//file.flv

可以使用VLC这个播放器或者ffplay（需要安装ffmpeg），VLC自行百度安装即可。 

ffmpeg安装：

sudo apt-add-repository ppa:jon-severinsson/ffmpeg
sudo apt-get update
sudo apt-get install ffmpeg
