nigix安装

树莓派安装nginx，参考http://blog.csdn.net/zizi7/article/details/54347223

1. 下载PCRE 并安装. 

     主页地址： ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/

     ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.38.tar.gz

2.  解压 tar -xzvf pcre-8.38.tar.gz

     cd pcre-8.38

　  cmake .

     sudo make

     sudo make install

3.  安装OpenSSL 

　　sudo apt-get install libssl-dev

4.  下载nginx 和 nginx rtmp 模块

　　下载nginx源码

　　 http://nginx.org/download/nginx-1.10.0.tar.gz

　　 解压 tar -zxvf nginx-1.10.0.tar.gz

　　下载nginx rtmp 模块源码

　　https://codeload.github.com/arut/nginx-rtmp-module/zip/master

　　解压unzip master，解压到nginx-rtmp-module-master文件夹

　　执行nginx 编译配置

      ./configure --add-module=/path/to/nginx-rtmp-module-master

      sudo make
      sudo make install

5.   启动nginx

      nginx 默认安装目录 /usr/local/nginx

      /usr/local/nginx/sbin 目录下nginx 服务器主程序， 启动 sudo ./nginx

6.   查看

     /usr/local/nginx/sbin$ ps -ef | grep nginx
        root      1394  1474  0 18:11 ?        00:00:00 nginx: master process ./nginx
        nobody    1395  1394  0 18:11 ?        00:00:00 nginx: worker process
         1570  1027  0 18:22 pts/32   00:00:00 grep --color=auto nginx

7.  在浏览器中输入 http://localhost/  ， 可以看到nginx 的首页

       Welcome to nginx!
       If you see this page, the nginx web server is successfully installed and working. Further configuration is required.
       For online documentation and support please refer to nginx.org. 
       Commercial support is available at nginx.com.
       Thank you for using nginx.

8. 添加rtmp 支持

       sudo vi conf/nginx.conf

rtmp {
     server {
         listen 1935;
         application live {
             live on;
             record off;
         }
     }
 }

9, 重启 nginx

     sudo ./sbin/nginx -t

     sudo ./sbin/nginx -s reload

10. 添加测试源， 推流到服务器

      ffmpeg -re -i ~/testcontent/MP4_H.264_MP_L3.1_720P_1Mbps_29.585fps_AAC_LC.mp4 -c copy -f flv rtmp://192.168.36.29:1935/live

      或者直接采集屏幕

      ffmpeg -f x11grab -follow_mouse centered -r 25 -s cif -i :0.0 -f flv rtmp://192.168.36.29:1935/live

11. 使用vlc在局域网机器上打开rtmp测试流

      rtmp://192.168.36.29:1935/live
