Please please please can someone help me setup my VPS? It's got apache and webmin installed, and it's CentOS. But I can't figure out how to install PHP! I just want to be able to host my vbulletin forum on it. Can anybody help?
Probably the easiest way is to start off with a brand new CentOS install and then install Webmin & Virtualmin using the Virtualmin install script from http://www.virtualmin.com/download.html That will install Virtualmin/Webmin and a LAMP stack - pretty much everything you're gonna need all in one shot.
If you can't install php maybe running a VPS isn't for you. Most forums can do well with shared hosting. How many members/posts do you have?
