I have a VPS with bluehost and have root access. I have a client (account within whm) who wants to install OpenProject.  I figured I would have to install as root and then point a subdomain from their account to mine.  I went through the installation process of openProject and it installed the directory to /opt/openproject.  (I would prefer this entire thing be in the cpanel account but couldn't figure out how).  The question is how can I point the root directory of the sub account to the root folder for the project?  as example if the subdomain I created is in an account called stocksguy and i created a subdomain and postgres domain in that cpanel (subdomain goes to ex. projects.stocksguy.com)  How do I point that subdomain outside of the subaccount back to the directory in root?
