nginx-rtmp 之统计在线clients

1. 使用Statistics 模块中的以下两个命令来实现统计在线人数的功能

• ​rtmp_stat​

• ​​rtmp_stat_stylesheet​​

# HTTP can be used for accessing RTMP stats
http {

server {

listen      8080;

# This URL provides RTMP statistics in XML
location /stat {
rtmp_stat all;

# Use this stylesheet to view XML as web page
# in browser
rtmp_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 here
root /path/to/stat.xsl/;
            }
    }

2. 但是ngx_rtmp_stat_module 不支持多进程。这个问题通过这个补丁​​per-worker-listener​​优化。

步骤：

1. 克隆per-worker-listener ： ​​https://github.com/arut/nginx-patches.git ​​到nginx 目录下面

2. 打补丁
