[07-Dec-2015 17:07:08] NOTICE: [pool www] 'group' directive is ignored when FPM is not running as root查看php-fpm日志发现以上提示，尝试将php-fpm的user和group修改成当前用户所匹配的，错误依旧。
通过lsof -Pni4 | grep LISTEN | grep php看到php-fpm确实是以当前用户而非root用户运行。

php-fpm 51553 joshua 0u IPv4 0xef21d7f98be9663 0t0 TCP 127.0.0.1:9056 (LISTEN)改fpm配置让fpm以你想要用户运行，
sudo vim /etc/php-fpm.d/www.conf
