ubuntu下使用nginx搭建流媒体服务器，实现视频点播

为了实现视频点播和直播，整了一天，看了N多博客，终于有了不小进展，在这里分享给大家。

什么是视频点播？可能你对这个名词不熟悉，但是爱奇艺，腾讯视频等这些视频播放软件想必你肯定知道。没错，视频点播就是在线观看某个视频。额，视频直播？这个就不解释了吧，美女直播，游戏直播等等，哈哈。

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

mkdir work

cd work

wget http://nginx.org/download/nginx-1.10.3.tar.gz 
wget http://zlib.net/zlib-1.2.11.tar.gz 
wget https://ftp.pcre.org/pub/pcre/pcre-8.40.tar.gz 
wget https://www.openssl.org/source/openssl-1.0.2k.tar.gz 
wget https://github.com/arut/nginx-rtmp-module/archive/master.zip[/code] 
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
