Question

I have an application with Laravel 4, that runs in localhost correctly, but when I uploaded it in my host I received the error .

app>config>database.php file is:

Answer 1

You must find out the credentials of Database host, Database Name , Database Username and Database Password . (If any prefix for tables too) and then replace it with the current credentials.

Use the concept of environments and store values in ENV variables :

http://laravel.com/docs/4.2/configuration

You can store Env Variables as array in .{ENV_NAME}.env.php and access those variables as $_ENV['variable_name'].

Answer 2

Check your mysql database is running perfectly or not. Then check you db user root in mysql with no password and restart your server.

Answer 3

Maybe you should add double-quotes for password in env:

# Config: database
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=db_name
DB_USERNAME=db_user
DB_PASSWORD="db_password"

and

php artisan config:clear

Answer 4

This worked for me:

php artisan config:clear

Even though I changed the config details in the .env file, I was getting the Access denied error. Running the above command will clear configuration cache file and hence laravel will read the fresh data from the .env file.
