I have installed Laravel 5 successfully and changed MySQL credentials in database.php file in config directory to \'
mysql\' => [
\'driver\'
The .env file should have same database name , username and password as in the mysql database and check whether all permissions are granted to the user for accessing the database or not. I solved my problem by adding the cpanel username in front of database name and username like jumbo_admingo and jumbo_user1 respectively where jumbo is my cpanel username and admingo is the database name i created in mysql and user1 is the user which has been provided the access to the database admingo. THIS SOLVED MY PROBLEM.
