php与nginx配置，不能运行php程序

查看nginx日志中发现下述报错内容：

2013/01/15 12:15:46 [error] 1707#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: XXX, server: _, request: "GET /phpif.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: XXX

解决手法：

/etc/init.d/php-fpm restart   重启php，

必要的时候再重启下service nginx restart
