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。
