Increase post_max_size for alt php for specific user

Edit the alt_php.ini file for user

cagefsctl -e USER

When inside CageFS for the user then run the following:

nano /opt/alt/phpXX/link/conf/alt_php.ini

Add the following to this file:

max_execution_time=300
memory_limit=512M
post_max_size=256M
upload_max_filesize=256M

The above can be pasted between the following two lines:

;>=== Start of PHP Selector Custom Options ===
;<=== End of PHP Selector Custom Options =====

Next, exit CageFS for the user:

exit

Edit the alt_phpxx.cfg

nano /home/USER/.cl.selector/alt_phpxx.cfg

This is necessary to ensure it has the same limits as the alt_php.ini otherwise the alt_php.ini of the user inside CageFS will be overwritten

Rebuild alt-php-ini

cagefsctl --rebuild-alt-php-ini

To enable higher post_max_size for the whole server, simply add more sizes under post_max_size here:

nano /etc/cl.selector/php.conf
