apache wizzards heed my call

mehmehmeh

I am trying to set up a single magento backend installation on a vps that will host multiple stores on multiple domains. my VPS has Cpanel WHM and Cpanel for the accounts. Because I will need seperate ssl certificates for each domain this will involve multiple Cpanel accounts (parked and add-on domains won't allow for the multiple ssl certifcates to be installed)

I first tried to solve this with symbolic links but when the site was accessed from the second domain I don't think it had privileges to the php in the main account, or the sql database.

maindomain.com <- magento is installed here, cpanel user is maindomain
domaintwo.com <- second domain, cpanel user is domaintwo

I think I have this solved by editing the vhost file for the second domain from this

is there anything I need to be concerned about going this route? Since it is on a VPS that only I am using, security shouldn't be an issue?
