The LAMP stack (Linux, Apache, MySQL, PHP) is a group of open source software that is typically installed together to enable a server to host dynamic PHP websites and web apps. This guide includes the steps to set up a LAMP stack on Ubuntu 14.04, on a single server, so you can quickly get your PHP application up and running.
A more detailed version of this tutorial, with better explanations of each step, can be found here.
When prompted, set and confirm a new password for the MySQL “root” user:
At the prompt, enter the password you set for the MySQL root account:
MySQL root password prompt:Enter current password for root (enter for none):
OK, successfully used password, moving on...
At the next prompt, if you are happy with your current MySQL root password, type “n” for “no”:

If you see a PHP info page, PHP processing is working:
Delete the test PHP script:

Remember the final critical step…
Restart Apache to put the change into place: sudo service apache2 restart
For some reason I managed to overlook this step, and while everything appeared to be functioning, I kept getting unexplainable errors that appeared (to the professionals whom I consulted) to be a misconfiguration of the PDO drivers, which I was told meant that PHP could not connect to MySQL.
After about a week of trouble-shooting and head-banging on my desk, this simple (overlooked) restart command solved all my problems. Ouch.
