安装Nginx

1.环境准备

yum install –y pcre pcre-devel
yum install –y zlib zlib-devel

2.下载nginx及rtmp模块

wget  http://nginx.org/download/nginx-1.6.2.tar.gz

tar xzvf nginx_1.6.2.tar.gz

git clone git://github.com/arut/nginx-rtmp-module.git

3.编译nginx-rtmp

cd nginx-1.6.2
./configure --prefix=/usr/local/nginx --add-module=../nginx-rtmp-module --with-http_stub_status_module
make
make install
安装完成后，nginx位于/usr/local/nginx/sbin目录下，配置文件nginx.conf在/usr/local/nginx/conf目录下

-------------测试nginx是否安装正确-----------------

cd /usr/local/nginx

./sbin/nginx -c ./conf/nginx.conf

打开网页http://localhost，如果显示Welcome表示安装下正确，如果没有显示，请查看一下nginx的日志。

4.在服务器上部署ckplayer等视频插件

下图是我的效果：

5.使用ffmpeg切割视频

ffmpeg -i /home/file/test.mp4 -strict -2 -c:v libx264 -c:a aac -f hls m3u8 /home/video/hls/test2.m3u8

(1). /home/file/test.mp4是原视频的路径

(2). /home/video/hls/test2.m3u8是切片后的视频地址

6.修改conf文件通过http协议发布切片后的视频

cd /usr/local/nginx/conf 切换到nginx的安转目录
vi ./nginx.conf

rtmp{
    server{
        listen  1935;
        application myapp{
            live    on;
        }
        application hls{
            live on;
            hls on;
        }
    }
}


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       8090;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

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

    location /images/ {
            root   /usr/local/nginx/html;
            index  index.html index.htm;
        }

    location /hls {
        types{
        application/vnd.apple.mpegurl   m3u8;
        video/mp2t  ts;
        }
        root /root/video;
        add_header Cache-Control no-cache;
            add_header Access-Control-Allow-Origin *;
    }

这样就可以通过http://yourIP:8090//hls/test2.m3u8访问切片后的视频
