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：

重启Nginx
root@iZ239kcyg8rZ:/usr/local/nginx/conf# service nginx restart * Stopping Nginx Server... [ OK ] * Starting Nginx Server... [ OK ] root@iZ239kcyg8rZ:/usr/local/nginx/conf#
