how to configure laravel 5 in ubuntu 12.04?

i installed laravel5 in Ubuntu 12.04 and I have updated version of xampp with php 5.5.1. Actually i don't want to make any mistake thats why i asked this questions because most of the time i had face pdo exception plus sql server errors only because of wrong config settings.
