Linux下nginx的安装及点直播使用示范

一、准备工作:

Red hat 5.5

nginx-1.11.5.tar.gz、openssl-1.0.1i.tar.gz、zlib-1.2.8.tar.gz、pcre-8.32.tar.gz、yamdi-1.4.tar.gz、nginx_mod_h264_streaming-2.2.7.tar.gz、nginx-rtmp-module-master.zip

二、安装步骤:

1、安装相关工具包:

1)zlib

# tar xvf zlib-1.2.8.tar.gz

# cd zlib-1.2.8

# ./configure

# make

# make install

# cd ..

2)pcre

# tar zxvf pcre-8.32.tar.gz

# cd pcre-8.32

# ./configure

# make

# make install

# cd ..

3)yamdi

yadmi的作用是为flv文件添加关键帧,才能实现拖动播放

# tar xzvf yamdi-1.4.tar.gz

# cd yamdi-1.4

# make

# make install

# cd ..

4)openssl

# tar -zxvf openssl-1.0.1i.tar.gz

# cd openssl-1.0.1i

# ./config

# make

# make install

2、配置安装nginx

1)配置编译安装nginx

# unzip nginx-rtmp-module-master.zip

# tar zxvfnginx_mod_h264_streaming-2.2.7.tar.gz

#tar zxvf nginx-1.11.5.tar.gz

#cd nginx-1.11.5

#./configure --prefix=/home/nginx--add-module=../nginx_mod_h264_streaming-2.2.7 --with-pcre=/source/pcre-8.32--with-zlib=/source/zlib-1.2.8 --with-openssl=/source/openssl-1.0.1i--add-module=../nginx-rtmp-module-master

出现如下情况,即配置完成:



#make

遇到如下错误:

1、



打开nginx_mod_h264_streaming-2.2.7/src/ngx_http_streaming_module.c文件,修改第158行如下:



改为:



2、



找到nginx-1.11.5/objs/Makefile文件,将里面的-Werror去掉。

重新#make

#make install

2)修改配置文件

#vi /home/nginx/conf/nginx.conf

改为如下内容:

#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;

 

worker_rlimit_nofile 51200;

events {

   use epoll;

   worker_connections  51200;

}

 

rtmp {

 server {

   listen 1935;

   chunk_size 4000;

   application vod {

     play /opt;

}

application myapp {

             live 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;

   add_header Access-Control-Allow-Origin *;

   add_header Access-Control-Allow-Headers X-Requested-With;

   add_header Access-Control-Allow-Methods GET,POST,OPTIONS;

   server {

       listen       81;

       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;

   #    }

   #}

         #VOD for FLV by RTMP

           server

           {

             listen 8081;

             location /stat

             {

               rtmp_stat all;

               rtmp_stat_stylesheet stat.xsl;

             }

 

             location /stat.xsl

             {

               root /opt/nginx_http_rtmp/nginx-rtmp-module/;

             }

       }

 

}

3)设置跨域

在/home/nginx/html/目录下建立crossdomain.xml文件,填写如下内容:

<?xml version="1.0"encoding="utf-8"?>

<cross-domain-policy>

         <allow-access-fromdomain="*"/> 

</cross-domain-policy>

保存。

4)打开nginx测试:

#cd /home/nginx/sbin

#./nginx

打开浏览器输入http://ip可看到nginx已经启动的画面,如下:



9、或者执行

netstat -ltn 

 可以看到80端口已经启用

结束nginx执行

./nginx -s stop或者./nginx -squit 

 一个是强制快速结束,一个是温柔结束.

完成

三、使用:

1、rtmp点播与直播:

   在/home/nginx/conf/nginx.conf里,下面的代码负责点播与直播

rtmp {

 server {

   listen 1935;

   chunk_size 4000;

   application vod {

     play /opt;

}

application live {

             live on;

    }

  }

}

点播:将视频文件放到/opt目录下,vlc里输入:

rtmp://192.168.0.204/vod/sample.mp4

直播:

ffmpeg -re -i /test.mp4 -vcodec copy -f flvrtmp://192.168.0.204/live/test

rtmp://192.168.0.204/live/test

 

2、HLS的点播、直播

点播:

在/home/nginx/conf/nginx.conf里,下面的代码负责点播

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;

       }

(1)使用ffmpeg将mp4格式文件转成TS格式文件:

ffmpeg -y -i input.mp4 -vcodec copy -acodeccopy -vbsf h264_mp4toannexb output.ts
(2)使用ffmpeg将TS文件切成ts分片并产生m3u8文件:

ffmpeg -i file.ts -c copy -map 0 -f segment-segment_list playlist.m3u8 -segment_time 2 output%03d.ts
将所得的ts分片和m3u8文件放到/home/nginx/html 目录下 

(3)vlc输入[ http://192.168.0.204:80/playlist.m3u8 ]即可看到点播视频 

直播:

(1)执行:ffmpeg -re -i rtsp://192.168.0.185:8557/h264 -codec copy -map 0 -fsegment -segment_list /video/playlist.m3u8 -segment_list_flags +live-segment_time 10 /video/out%03d.ts

(2)将所得的ts分片和m3u8文件放到/home/nginx/html 目录下 

(3)vlc输入[ http://192.168.0.204:80/playlist.m3u8 ]即可看到点播视频
