[phpMyAdmin] You probably tried to upload too large file. Please refer to documentation for ways to workaround this limit.

PHP has a file size restriction for uploads.

Find PHP.ini

php -i | grep "Loaded Configuration File"

update

upload_max_filesize = 128M 
post_max_size = 128M 
max_execution_time = 900 
max_input_time = 60

restart apache with


systemctl restart httpd.service
