my php info looks like this:

Configuration File (php.ini) Path /etc/php5/fpm
Loaded Configuration File /etc/php5/fpm/php.ini
Scan this dir for additional .ini files /etc/php5/fpm/conf.d
Additional .ini files parsed /etc/php5/fpm/conf.d/apc.ini, /etc/php5/fpm/conf.d/curl.ini, /etc/php5/fpm/conf.d/gd.ini, /etc/php5/fpm/conf.d/mcrypt.ini, /etc/php5/fpm/conf.d/mysql.ini, /etc/php5/fpm/conf.d/mysqli.ini, /etc/php5/fpm/conf.d/pdo.ini, /etc/php5/fpm/conf.d/pdo_mysql.ini, /etc/php5/fpm/conf.d/suhosin.ini, /etc/php5/fpm/conf.d/xdebug.ini

So i addet to
/etc/php5/fpm/conf.d/mysql.ini, and /etc/php5/fpm/conf.d/mysqli.ini,

[mysql]
max_allowed_packet=32M
[mysqld]
max_allowed_packet=16M

restart nginx

but no change seems not even to be parsed as there is no change in the php info
