Mac搭建直播服务器

1. 用brew安装nginx

brew tap homebrew/nginx

网上一般这个时候直接brew安装了，不过最好先update一下

sudo chown -R $(whoami):admin /usr/local
brew update

然后再安装nginx

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

安装完了，最好按提示提升一下ngnix权限，否则别的机器可能连不上

sudo chown root:wheel /usr/local/Cellar/nginx-full/1.10.2/bin/nginx
sudo chmod u+s /usr/local/Cellar/nginx-full/1.10.2/bin/nginx

2. 配置nginx

brew info nginx-full
可以看到nginx的配置文件路径

Docroot is: /usr/local/var/www

The default port has been set in /usr/local/etc/nginx/nginx.conf to 8080 so that
nginx can run without sudo.

nginx will load all files in /usr/local/etc/nginx/servers/.

- Tips -
Run port 80:
 $ sudo chown root:wheel /usr/local/Cellar/nginx-full/1.10.2/bin/nginx
 $ sudo chmod u+s /usr/local/Cellar/nginx-full/1.10.2/bin/nginx
Reload config:
 $ nginx -s reload
Reopen Logfile:
 $ nginx -s reopen
Stop process:
 $ nginx -s stop
Waiting on exit process
 $ nginx -s quit

打开/usr/local/etc/nginx/nginx.conf，在文件最后加上下面配置

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

3. 测试

启动ngnix后就能推流上去了

nginx

推流用ffmpeg最方便

ffmpeg -re -i /Users/annidy/Movies/完美的星球720p.mp4 -vcodec copy -f flv rtmp://localhost:1935/fx/room

room房间号无所谓，随便填。然后就可以直接用VLC播了。

播放地址 rtmp://localhost:1935/fx/room

4. 开启录制

ngnix rtmp moudle的录制功能有助于调试，打开很简单，修改配置即可。

rtmp {
    server {
        listen 1935;
        application fx {
            live on;
            record all;
            record_path /tmp;
            record_suffix -%Y-%m-%d-%H%M.flv;
        }
    }
}

重新加载一下配置文件

nginx -s reload

录制的文件存放于/tmp目录下，当然这是随便可以改的。
