File location:

/etc/php/8.3/fpm/php.ini

Update the following values:

upload_max_filesize = 100M
post_max_size = 100M
memory_limit = 256M
max_execution_time = 300

Notes:

• upload_max_filesize = maximum size allowed for a single uploaded file
• post_max_size = maximum total size of POST request (must be greater than or equal to upload_max_filesize)
• memory_limit = maximum memory a PHP script can consume
• max_execution_time = maximum execution time in seconds

Restart PHP-FPM:

sudo systemctl restart php8.3-fpm

If large uploads return “413 Request Entity Too Large”, update your Nginx server block:

server {
    server_name api-warehouse.quizz.vn;
    root /var/www/warehouse/warehouse-be/public;
 
    client_max_body_size 100M;
}

Reload Nginx:

sudo nginx -t
sudo systemctl reload nginx

Check current PHP limits:

php -i | grep upload_max_filesize

Or create a temporary file:

<?php phpinfo();
