php-cgi 9000端口被占用，nginx无法打开php页面(The page you are looking for is temporarily unavailable.Please try)

windows 环境下采用nginx+php架构，不能正常访问php页面。页面错误提示：The page you are looking for is temporarily unavailable.Please try again later，查看nginx error log，错误信息：upstream prematurely closed connection while reading response header from upstream,…fastcgi://127.0.0.1:9000".

查看系统9000端口连接状态：

    netstat -ano | find ":9000"

    TCP    127.0.0.1:9000         0.0.0.0:0              LISTENING       1672

发现9000端口被占用，使用任务管理器查看PID 1672进程为pplive。

杀死pplive进程或者更改fastcgi端口，php页面访问正常。

    "C:\Program Files\php5\php-cgi.exe" -b 127.0.0.1:9001 -c "C:\Program Files\php5\php.ini"  

该死的pplive,
