Updated PHP from 5.1 to 5.3.9 and accidentally uninstalled Plesk (Linux)

view full story

http://serverfault.com – I was updating PHP and when attempting to install 5.3.9, I got conflicts with 5.1 so I (rather stupidly) ran yum remove php php-* and I think that this removed the plesk plugin and I am able to access all the sites hosted, but not the actual plesk panel. The PSA folder is there in /usr/local/. When I tried reinstalling, and it returned You have Plesk v 10.10.1 installed. Any ideas? (HowTos)
