Changing the php file upload limit in Ubuntu Linux

Create a PHP page and test it.
<?php
// Show all information, defaults to INFO_ALL
phpinfo();
?>

Now goto terminal

which will show you the actual maximum file size. In order to change that open a ssh connection to your server and edit the file /etc/php5/apache2/php.ini with

sudo nano /etc/php5/apache2/php.ini

search for “upload_max_filesize” with Ctrl-W and change “2M” to “20M”. Save the file with Ctrl-O and exit with Ctrl-X. Restart the apache server with

sudo /etc/init.d/apache2 restart
