BUG: I heard somewhere that running PHP-FPM as a root could be potentially not good for security, so I decided to try to launch master process as www-data user: su -c "php-fpm &" -s /bin/sh www-data But, it returns an error: ERROR: failed to open error_log (/usr/local/var/log/php-fpm.log): Permission denied (13) ERROR: failed to post process the configuration ERROR: FPM initialization failed I have tried to change permissions of php-fpm.log file and /usr/local/var/log folder, even to 777, also tried various owners with chmod command ( my current user, www-data, root, etc ) But, that does not eliminate an error ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67445&edit=1
