首先修改 /etc/php/7.0/fpm/pool.d/www.conf
[...] ; Unix user/group of processes ; Note: The user is mandatory. If the group is not set, the default user's group ; will be used. user = root group = root [...]
接著修改 /lib/systemd/system/php7.0-fpm.service
將
ExecStart=/usr/sbin/php-fpm7.0 --nodaemonize --fpm-config /etc/php/7.0/fpm/php-fpm.conf
修改為
ExecStart=/usr/sbin/php-fpm7.0 --allow-to-run-as-root --nodaemonize --fpm-config /etc/php/7.0/fpm/php-fpm.conf
重新載入PHP
systemctl daemon-reload /etc/init.d/php7.0-fpm restart
完成
