- 启动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
开始的时候，使用本机wyc用户名及group名staff,发现session写到了/var/tmp/下面，wyc账户没有权限写，切换到root账户，
切换到root账户,及wheel组
php-fpm启动项里有-c可以允许用root启动
-R, --allow-to-run-as-root
Allow pool to run as root (disabled by default)
2.切换Nginx的账户，默认nobody，切换成root账户，user root 会报错
➜ conf sudo /usr/local/openresty/nginx/sbin/nginx -s reload
nginx: [emerg] getgrnam("root") failed in /usr/local/openresty/nginx/conf/nginx.conf:3
必须加上wheel组名就好了
