Apache2/PHP increase upload file size

Edit the php.ini Use a standard text editor to open

/etc/php/apache2/php.ini

, search for the following variables and change/increase these to (as desired but a general guideline is mentioned):

memory_limit = 512M
upload_max_filesize = 100M
post_max_size = 100M

Some more values to change if you want a better performance of your web server:

max_execution_time = 600
max_input_time = 600
memory_limit = 1024M

Save and close the editor/file and restart the apache web server with:

service apache2 restart

or

systemctl restart apache2
