in response to "dreamcat4 at gmail dot com" about enabling logs in php-fpm
i *hate* going blind, so enabling logs is generally the first thing i do...
by doing dreamcat4 suggestion, logs got enabled but mixed with php process logs ... instead doing that and to isolate logs from [www] worker pool in its own file, these directives worked for me in "www" worker .ini file (you have to set directories and permissions before)
php_admin_flag[log_errors] = on
php_admin_value[error_log] = /var/log/php-fpm/www-error.log
