nginx和php-fpm的用戶權限

1. 啓動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帳戶沒有權限寫，切換到root帳戶，

切換到root帳戶,及wheel組

php-fpm啓動項裏有-c能夠容許用root啓動
-R, --allow-to-run-as-root
Allow pool to run as root (disabled by default)

2.切換Nginx的帳戶，默認nobody，切換成root帳戶，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組名就行了
