如果你想检查PHP-FPM是否正确运行，或者在不依赖Nginx或Apache等Web服务器的情况下查看它的配置，你可以按照下面的例子进行。
配置
安装fcgi 软件包，在/usr/local/etc/php-fpm.d/www.conf 文件中加入以下几行，并重新启动 PHP-FPM 服务器。
pm.status_path=/status
ping.path=/ping
ping.response=pong

详细状态格式
上述输出可以通过使用QUERY_STRING="full&{format}"... 例如：QUERY_STRING="full&json"... 打印成JSON、XML和HTML格式。如果你想在浏览器中看到这些细节，你也可以在Nginx配置中创建一个location 块。
