1. 使用Statistics 模塊中的以下兩個命令來實現統計在線人數的功能

• rtmp_stat
  • rtmp_stat_stylesheet

# HTTP can be used for accessing RTMP statshttp {server {listen 8080;# This URL provides RTMP statistics in XMLlocation /stat {rtmp_stat all;# Use this stylesheet to view XML as web page# in browserrtmp_stat_stylesheet stat.xsl;}location /stat.xsl {# XML stylesheet to view RTMP stats.# Copy stat.xsl wherever you want# and put the full directory path hereroot /path/to/stat.xsl/;}}

2. 但是ngx_rtmp_stat_module 不支持多進程。這個問題通過這個補丁per-worker-listener優化。

步驟：

1. 克隆per-worker-listener ： https://github.com/arut/nginx-patches.git?到nginx 目錄下面

2. 打補丁

3?make &make install
