While browsing through the public Linode Stack Scripts for RHEL distros I noticed there was no fully automated LAMP stack script so I took the liberty of creating one to mirror those provided in the Ubuntu section. Please note that I added a install_personal function. You can duplicate this script and add any packages you like to this function.
The majority of the credit should go to Linode user justintime for his StackScript Bash Library for RH Derivatives script which was a port from the Ubuntu section. I merely added a wrapper around his Stack Script and the base stack script.
