How to change CPanel account root directory.

Step 1

Update variable documentroot in following two file:

sudo nano /var/cpanel/userdata/<cpanel-username>/<example.com>
sudo nano /var/cpanel/userdata/<cpanel-username>/<example.com>_SSL

Replace <example.com> to your actual domain.

You need update following line in both files:

documentroot: /home/<cpanel-username>/public_html

to your target folder.

Eg:

documentroot: /home/<cpanel-username>/public_html/public

Step 2

Then edit:

sudo nano /var/cpanel/userdata/<cpanel-username>/<example.com>.php-fpm.yaml

and add following line

php_admin_value_doc_root: { name: 'php_admin_value[doc_root]', value: /home/<cpanel-username>/public_html/public }

Final file will look like:

---
_is_present: 1
php_admin_value_doc_root: { name: 'php_admin_value[doc_root]', value: /home/<cpanel-username>/public_html/public }

/scripts/restartsrv_apache_php_fpm
/scripts/restartsrv_httpd
service httpd restart
