Bug #67445 [NEW]: cannot run PHP-FPM master process by www-data user

From: multitor4 at gmail dot com Operating system: Debian PHP version: 5.5.13 Package: FPM related Bug Type: Bug Bug description:cannot run PHP-FPM master process by www-data user Description: ------------ My PHP-FPM configuration works: I could run php-fpm with sudo php-fpm & command, and with ps aux | grep "php-fpm" I could see one master process running as root, and two daughter processes running as www-data user: (output stripped for convenience) root php-fpm: master process (/usr/local/etc/php-fpm.conf) www-data php-fpm: pool www www-data php-fpm: pool www Webserver works perfectly as well. 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 bug report at https://bugs.php.net/bug.php?id=67445&edit=1 --
