Introduction

Nginx is a very good open source server. It is a very good choice to use it as a hls or rtmp streaming media server. I have sorted out the installation process on the Internet, shared it with everyone and made a note.

steps to install

1. Install Homebrow

Homebrew, referred to as brew, is a package management tool on Mac OSX. It can easily install or uninstall software on Mac. It can be said that Homebrew is the apt-get and yum artifact under mac.

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

If you have already installed and want to uninstall:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

2. Install Nginx server

Increase nginx the extension of the pair; that is, download from github, the extension of home-brew to ngixnx

brew tap homebrew/nginx

3. Install Nginx server and rtmp module

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

This installation takes a relatively long time. By operating the above steps, the nginx and rtmp modules are installed. Let's start to configure the nginx rtmp module.

First, let's take a look at where our nginx is installed

brew info nginx-full

After executing the above command we can see the information

nginx安装所在位置 /usr/local/Cellar/nginx-full/1.10.1/bin/nginx
nginx配置文件所在位置 /usr/local/etc/nginx/nginx.conf
nginx服务器根目录所在位置 /usr/local/var/www

执行命令，测试下是否能成功启动nginx服务

nginx

命令行如下图所示

在浏览器地址栏输入：http://localhost:8080 （直接点击）

出现Welcome to nginx ,代表nginx安装成功了。

4、配置rtmp

用Xcode打开nginx.conf, 找到/usr/local/etc/nginx/nginx.conf 文件,拖入到Dock中的Xcode,就可以打开.

或者打开Finder Shift + command + G前往，用记事本工具打开nginx.conf.

http {
    ……
}
#在http节点下面(也就是文件的尾部)加上rtmp配置：
rtmp {
    server {
        listen 1935;
        application zbcs {
            live on;
            record off;
        }
    }
}

说明：

rtmp是协议名称
server 说明内部中是服务器相关配置
listen 监听的端口号, rtmp协议的默认端口号是1935
application 访问的应用路径是 zbcs
live on; 开启实时
record off; 不记录数据

5. 保存文件后，重新加载nginx的配置文件（这一步很重要）

nginx -s reload

6. 安装ffmepg工具

brew install ffmpeg

安装这个需要等一段时间, 这时你可以准备一个视频文件作为来推流，然后安装一个支持rtmp协议的视频播放器.Mac下可以用 VLC(点击下载)

7、通过ffmepg命令进行推流

ffmpeg -re -i 你的视频文件的绝对路径(如/Users/lideshan/Downloads/Demo.mp4)  -vcodec copy -f flv rtmp://localhost:1935/zbcs/room
// 如：ffmpeg -re -i /Users/jiangys/Documents/Document/demo.mp4  -vcodec copy -f flv rtmp://localhost:1935/zbcs/room

这里zbcs是上面的配置文件中,配置的应用的路径名称;后面的room可以随便写。

推流界面：

8. 验证视频

然后电脑上打开vlc这个播放器软件点击File---->Open Network 在弹出来的框中选择Network然后输入URL:

rtmp://localhost:1935/zbcs/room

双击播放

播放界面

报错处理

1.ffmepg命令推流的时候，提示连接失败。[tcp @ 0x7ff162504b60] Connection to tcp://localhost:1935 failed (Connection refused), trying next address

出现这个错，是因为配置了nginx.conf后，需要重启nginx。输入命令重启后就没有问题了

nginx -s reload

2.安装完nginx后，在浏览器地址栏输入：http://localhost:8080 显示打不开网页

解决方式：由于安装后nginx服务器，有时需要等上几分钟才生效。如果还不生效，测试下是否能成功启动nginx服务，命令

nginx

具体请参考“步骤安装”第三点。

另：当前只支持rtmp拉流，如果想要支持HLS ,请参考下一篇文章：
