redirect php-fpm output to nginx's error log
  • php process is wrapped like this: PHP file -> php-fpm -> nginx
  • basically means disable all facilities that catch output from the script on it's way to nginx
  • standard error output will the end in Nginx's logging facility

On CentOS

  • make sure your script does not set error_log
  • edit /etc/php-fpm.conf, disable line error_log = /var/log/php-fpm/error.log
  • edit /etc/php-fpm.d/www.conf, disable line starting with php_admin_value[error_log] = ...
  • restart fpm: systemctl restart php-fpm
