Set post_max_size for PHP

Hello! I'm trying to setup my Wordpress site, and I need to set postmaxsize value. Default value is 8 mb, and I'm trying to make it bigger. I've setup it everywhere I found:

sudo rgrep post_max_size
Binary file usr/sbin/php-fpm7.0 matches
Binary file usr/lib/cgi-bin/php7.0 matches
usr/lib/php/7.0/php.ini-production:post_max_size = 128M
usr/lib/php/7.0/php.ini-development:post_max_size = 128M
usr/lib/php/7.0/php.ini-production.cli:post_max_size = 128M
Binary file usr/bin/php-cgi7.0 matches
Binary file usr/bin/php7.0 matches
etc/php/7.0/cgi/php.ini:post_max_size = 128M
etc/php/7.0/fpm/php.ini:post_max_size = 128M
etc/php/7.0/cli/php.ini:post_max_size = 128M

But phpinfo() always return 8Mb. What should I do wrong? I use 7.0 fpm and Nginx. How can I fix it? Thanks in advance!
