搭建流媒体服务

准备流媒体服务器Linux或Mac

编译并安装Nginx服务

配置RTMP服务并启动 Nginx 服务

Mac 上 安装 nginx rtmp 流媒体服务

Nginx介绍

Nginx是一个高性能的HTTP和反向代理web服务器,同时也提供了IMAP/POP3/SMTP服务。因它的稳定性、丰富的功能集、示例配置文件和低系统资源的消耗而闻名。
Nginx是一款轻量级的Web 服务器/反向代理服务器及电子邮件(IMAP/POP3)代理服务器,在BSD-like 协议下发行。其特点是占有内存少,并发能力强,事实上nginx的并发能力确实在同类型的网页服务器中表现较好,中国大陆使用nginx网站用户有:百度、京东、新浪、网易、腾讯、淘宝等。

1.安装nginx

执行安装

brew install nginx-full --with-rtmp-module

2.修改配置文件

查看一下nginx安装在什么地方

brew info nginx-full

nginx配置文件所在位置

/usr/local/etc/nginx/nginx.conf

3.运行nginx

nginx

浏览器地址栏输入:http://localhost:8080

nginx

4.配置rtmp

vi /usr/local/etc/nginx/nginx.conf

配置文件长这样:

#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;
}


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;
    #    }
    #}
    include servers/*;
}

我们需要在 在http节点后面加上rtmp配置

rtmp {
  server {
      listen 1935;  
    #直播流配置
      application rtmplive {
          live on;
      #为 rtmp 引擎设置最大连接数。默认为 off
      max_connections 1024;
       }
      application hls{

          live on;
          hls on;
          hls_path /usr/local/var/www/hls;
          hls_fragment 1s;
      }
   }
}

编辑完成之后,执行一下重新加载配置文件命令:

nginx -s reload

重启nginx

sudo /usr/local/opt/nginx-full/bin/nginx -s reload

安装ffmepg工具

1.安装ffmpeg

brew install ffmpeg

2.安装一个支持rtmp协议的视频播放器,Mac下可以用VLC

本地下载一个视频文件路径为

/Users/xx/Desktop/story.mp4

3.执行推流命令

ffmpeg -re -i /Users/xx/Desktop/story.mp4 -vcodec libx264 -acodec aac -strict -2 -f flv rtmp://localhost:1935/rtmplive/room

4.用vlc 然后打开 VLC 中 的 file -- Open Network, 直接输入代码中的 url:

rtmp://localhost:1935/rtmplive/room

然后进行播放.

5.手机推流只需把localhost:8080换成自己电脑的ip地址即可:

rtmp://10.0.0.17:1935/rtmplive/room
