Can't you host both sites off the same pi?
Was just thinking that.... how would I do it? It's just running a basic Apache server on there currently
AFAIK you need to set up a virtual host on Apache for each site.
Setting up vhosts is far easier than setting up and maintaining two servers for two sites.
Just edit your httpd.config file and restart httpd. Done.
Only reason to run two servers is if you needed two environments.
