How to add post_max_size and upload_max_filesize options seen in cPanel when using PHP Selector options

Question

How do you add the post_max_size and upload_max_filesize options seen in cPanel when using PHP Selector options?

Answer

1. Log in to the server via SSH as the 'root' user
2. Open /etc/cl.selector/php.conf in your preferred text editor

3. Search for post_max_size and change the default if desired, and add the desired values to the RANGE line, for example, change:

   CONFIG_TEXT: Range = 2M,4M,8M,16M,32M,64M,128M

   and add 1G:

   CONFIG_TEXT: Range = 2M,4M,8M,16M,32M,64M,128M,1G

   Note: The same can be done for upload_max_filesize and memory_limit as well

4. After saving the file with the desired changes, run the following command to force update CageFS:

   # /usr/sbin/cagefsctl --force-update

5. The adjustment should now be seen in cPanel under PHP Selector
