How to increase phpmyadmin file upload limit in centos?

Question

PHP

I know the topic is overused. But increasing post_max_size, memory_limit and upload_max_filesize to, say, 800m didn't help. Apache restarted and the whole server too (what if). The /etc/php.ini file rules. Uploading via upload dir is not interesting. How else can I increase the limit to 800MB?
Google is silent and pushes branches to debian (only there are 4 php.ini files in the deb and still their options do not work).
Installed PU vestacp + php7 on centos 7 (apache + nginx).
