Linux-Nginx+rtmp+ffmpeg搭建流媒体服务器

Nginx+rtmp+ffmpeg搭建流媒体服务器#

说明：

　　nginx搭建流媒体服务需要用到 nginx-rtmp-module 模块

具体操作步骤：

安装nginx#

（1）下载第三方扩展模块nginx-rtmp-module

# mkdir module && cd module        　　//创建一个存放模块的目录
# wget https://github.com/arut/nginx-rtmp-module/archive/master.zip        //下载模块
# unzip master.zip        　　　　　　　　//解压
# ls nginx-rtmp-module-master/         //查看模块目录

（2）编译安装nginx（说明：此处由于我这边已有lnmp运行项目的环境，直接动态添加的 nginx-rtmp-module模块；动态参加可参考：这里）

# yum -y install pcre-devel openssl openssl-devel        //安装依赖
# wget http://nginx.org/download/nginx-1.12.2.tar.gz        //下载nginx包
# tar xf nginx-1.12.2.tar.gz
# ./configure --prefix=/opt/nginx-1.9.5 --add-module=/root/module/nginx-rtmp-module-master --with-http_ssl_module    //编译安装nginx，并指定上面下载的模块路径
# make        
# make install

（3）修改nginx配置文件，添加如下内容并重新载入配置文件

# vim nginx.conf
rtmp {  
    server {  
        listen 1935;      #监听的端口号
        application myapp {     #自定义的名字
            live on;  
       }  
        application hls {  
            live on;  
            hls on;  
            hls_path /tmp/hls;   
            hls_fragment 1s;
            hls_playlist_length 3s;  
       }  
    } 
}
# /etc/init.d/nginx reload

user  root;
worker_processes  4;
worker_cpu_affinity 1000 0100 0010 0001;
worker_rlimit_nofile 30000;


#error_log  logs/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  30000;
    use epoll;
}

rtmp {  
    server {  
        listen 1935;  
        application myapp {  
            live on;  
       }  
       application hls {  
         live on;  
             hls on;  
             hls_path /tmp/rtmp/hls;  
             hls_fragment 1s;
         hls_playlist_length 3s;  
       }  
    } 
}


http {

    limit_req_zone  $binary_remote_addr  zone=req_one:10m rate=1r/s;

    autoindex off;
    include       /opt/nginx-1.9.5/conf/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" $http_x_forwarded_for $request_length $request_time "$upstream_response_time" "$upstream_addr" $host $server_addr';
                     
                      

    #access_log  logs/access.log  main;
    server_tokens off;
    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    gzip  on;
    gzip_min_length  1K;
    gzip_buffers   4 16K;
    gzip_comp_level   8;
    gzip_http_version 1.0;
    gzip_types    application/json  text/javascript  text/plain application/x-javascript text/css application/xml  text/xml;
    #gzip_types    application/json  text/javascript  text/plain application/x-javascript text/css application/xml  text/xml image/jpeg image/gif image/png;
    gzip_disable "MSIE [1-6]\.";
    client_max_body_size 500M;


    #server {
    #    listen 80 default;
    #    return 500;
    #}

    include /opt/nginx-1.9.5/conf/conf.d/*.conf;

    
}

完整nginx.conf

安装ffmpeg#

ffmpeg命令参考这位朋友的文章：https://www.jianshu.com/p/049d03705a81

（1）安装依赖

# yum install yasm -y

（2）下载ffmpeg并安装

# git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg    //下载ffmpeg
# cd ffmpeg
# ./configure --prefix=/usr/local/ffmpeg
# make
# make install

（3）拷贝命令到/usr/bin（方便后面调用）

# ls /usr/local/ffmpeg/        //查看安装目录生成的文件
bin  include  lib  share
# cp /usr/local/ffmpeg/bin/* /usr/bin/

测试#

（1）启用ffmpeg进行推流

# ffmpeg -i rtsp://192.168.1.175:554/11 -acodec aac -strict experimental -ar 44100 -ac 2 -b:a 96k -r 25 -b:v 500k -s 640*480 -f flv rtmp://192.168.1.11:1935/myapp/23
-i 要处理视频文件的路径，此处地址是一个监控摄像头
-s 像素
rtmp://192.168.1.11:1935/myapp/23  说明：rtmp://IP:PORT/ myapp指nginx配置文件中自定义的，22指输出文件的名字
-f 强迫采用flv格式
别的参数参考上面那位老兄的

（2）打开VLC 媒体——>流——>网络

（3）进入服务器查看输出的位置可以发现已生成文件

# ll /tmp/hls/
