- 啟動php-fpm
sudo php-fpm -c /etc/php.ini
[17-Sep-2018 00:36:59] ERROR: [pool www] please specify user and group other than root
[17-Sep-2018 00:36:59] ERROR: FPM initialization failed
開始的時候，使用本機wyc用戶名及group名staff,發現session寫到了/var/tmp/下面，wyc賬戶沒有權限寫，切換到root賬戶，
切換到root賬戶,及wheel組
php-fpm啟動項里有-c可以允許用root啟動
-R, --allow-to-run-as-root
Allow pool to run as root (disabled by default)
2.切換Nginx的賬戶，默認nobody，切換成root賬戶，user root 會報錯
➜ conf sudo /usr/local/openresty/nginx/sbin/nginx -s reload
nginx: [emerg] getgrnam("root") failed in /usr/local/openresty/nginx/conf/nginx.conf:3
必須加上wheel組名就好了
