获得订阅者人数,可以方便地显示观看流的客户数。

查看已经安装好的模块

/usr/local/nginx/sbin/nginx -V

安装从源编译Nginx和Nginx-RTMP所需的工具

sudo apt-get install build-essential libpcre3 libpcre3-dev libssl-dev

下载Nginx和Nginx-RTMP源码

wget http://nginx.org/download/nginx-1.7.5.tar.gz
wget https://github.com/arut/nginx-rtmp-module/archive/master.zip

提取Nginx和Nginx-RTMP源

tar -zxvf nginx-1.7.5.tar.gz
unzip master.zip

切换到Nginx目录

cd nginx-1.7.5

添加Nginx将编译的模块,包括Nginx-RTMP

./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_ssl_module --with-http_xslt_module --with-http_flv_module --with-debug --with-http_gzip_static_module --add-module=../nginx-rtmp-module-master

提示错误:

./configure: error: the HTTP XSLT module requires the libxml2/libxslt
libraries. You can either do not enable the module or install the libraries.

配置 --with-http_xslt_module 时提示 the HTTP XSLT module requires the libxml2/libxslt libraries:安装一下扩展

sudo apt-get install libxml2 libxml2-dev libxslt-dev

编译和安装Nginx与Nginx-RTMP。

make
sudo make install

安装Nginx初始化脚本

sudo wget https://raw.github.com/JasonGiedymin/nginx-init-ubuntu/master/nginx -O /etc/init.d/nginx
sudo chmod +x /etc/init.d/nginx
sudo update-rc.d nginx defaults

启动和停止Nginx生成配置文件

sudo service nginx start
sudo service nginx stop

观看安装是否成功:

/usr/local/nginx/sbin/nginx -V

安装结果

configure arguments: --prefix=/usr/local/nginx --user=www --group=www --with-http_ssl_module --with-http_xslt_module --with-http_flv_module --with-debug --with-http_gzip_static_module --add-module=../nginx-rtmp-module-master

修改Nginx 配置文件添加一下信息,在位置设置统计信息页面

location /stat {
    rtmp_stat all;
    allow 127.0.0.1;
}

创建一个简单的xsl样式表nclients.xsl提取流用户数

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="html"/>

<xsl:param name="app"/>
<xsl:param name="name"/>

<xsl:template match="/">
    <xsl:value-of select="count(//application[name=$app]/live/stream[name=$name]/client[not(publishing) and flashver])"/>
</xsl:template>

</xsl:stylesheet>

设置一个返回订阅者数量的位置

location /nclients {
    proxy_pass http://127.0.0.1/stat;
    xslt_stylesheet /home/www/nclients.xsl app=‘$arg_app‘ name=‘$arg_name‘;
    add_header Refresh "3; $request_uri";
}

Nginx.config 完整配置:
