ubuntu搭建nginx服务器实现视频直播点播

开发环境
Ubuntu 16.04

nginx的服务器的搭建

１．安装nginx的依赖库
sudo apt-get update
sudo apt-get install libpcre3 libpcre3-dev
sudo apt-get install openssl libssl-dev

２．安装ffmpag(视频点播，直播推流用)

$ add-apt-repository ppa:kirillshkrogalev/ffmpeg-next

$ apt-get update

$ apt-get install ffmpeg

３．安装vlc播放器(视频点播，直播拉流)

sudo apt-get install vlc
安装完成之后在ubuntu系统设置–详细详细–默认应用程序–视频选择VLC为默认视频播放器

４．建立源码编译的目录

$ mkdir nginx-src

$ cd nginx-src

５．下载源码仓库并解压
nginx源码
$ git clone https://github.com/nginx/nginx.git
nginx的rtmp模块源码
$ git clone https://github.com/arut/nginx-rtmp-module.git
（我下载的是nginx-1.8.1，nginx-rtmp-module）
下载完成后解压到 nginx-src

６．配置并编译nginx
使用nginx的默认配置，添加nginx的rtmp模块。
这里写图片描述
$cd nginx-1.8.1

$ sudo ./configure –add-module=../nginx-rtmp-module-master

$ sudo make

$ sudo make install

７.运行测试nginx

进入安装目录/usr/local/nginx，运行命令./sbin/nginx

$ cd /usr/local/nginx

$ sudo ./sbin/nginx

注意：以后所有的命令都在/usr/local/nginx目录运行，也nginx配置文件的相对目录。
如果对文件有修改需要重新启动一下nginx，在/usr/local/nginx目录

$ sudo 　./sbin/nginx -s reload

打开浏览器在地址栏输入：localhost。如果，如下图显示那样就证明您的nginx服务器搭建成功了

８.配置直播，点播
$cd 　/usr/local/nginx/conf
可以用gedit或者vim编辑内容如下，ｐｓ:主要添加rtmp直播点播模块

#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;
    chunk_size 4096;
    publish_time_fix on;

    application vod {
        play /home/pangrui/Videos/;
    }

              # 推流其一
              application live {
                      live on; #stream on live allow
                      allow publish all; # control access privilege
                      allow play all; # control access privilege
              }
             #推流其二
      application hls_alic {
                      live on;
                      hls on;
                      hls_path /home/pangrui/hls;
                      hls_fragment 5s;
              }
    }

}

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       80;
        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;
    #    }
    #}

}

９．使用ffmpeg向服务器推送一个视频
我们重新启动一下nginx

$ sudo ./sbin/nginx -s reload

$ sudo ffmpeg -re -i /home/pangrui/Videos/mv-gee.mp4 -c copy -f flv rtmp://localhost:1935/live/film

推荐 可用于浏览器播放

$ sudo ffmpeg -re -i /home/pangrui/Videos/mv-gee.mp4 -c copy -f flv rtmp://localhost:1935/hls_alic/film

10.vlc拉流播放
打开视频播放软件选用的是VLC media-> open network stream….
如图填写我们要点播的节目地址rtmp://localhost/vod/mv-gee.mp4 如图：

同理直播用
rtmp://localhost:1935/live/film
或者rtmp://localhost:1935/hls_alic/film
点击play即可播放！！！
注意，在hls_path的路径添加一个站点来访问即可！
推流还是用ffmpeg的命令来, 推流一段时间后, 你会发现在”/home/pangrui/hls”目录里, 有很多ts文件,
还有一个后缀”.m3u8”文件上面配置中的 server:8081 块, 就是为了能在外部能访问这些ts文件和m3u8文件。
如果是浏览器播放flv可参考如下代码:

<html>
<head>
    <link rel="stylesheet" href="http://vjs.zencdn.net/5.10/video-js.css">
head>
    <video id=example-video width=960 height=540 class="video-js vjs-default-skin" controls>
        <source
            src="film.m3u8"
            type="application/x-mpegURL">
    video>
    <script src="http://vjs.zencdn.net/5.10/video.js">script>
    <script src="https://npmcdn.com/videojs-contrib-hls@^3.0.0/dist/videojs-contrib-hls.js">script>
    <script>
        var player = videojs('example-video');
        player.play();
    script>
html>

申明：本文参考如下文章，取其可用部分舍弃不靠谱部分，自己动手搭建得到本文，后续会将推拉流移植到android设备,感谢。
