MySQL database connection works on Live Server, but not on Test Server

Question

I have a peculiar situation where the database connection works on the live server but not on my local computer.

I have the following connection script to access the database on both my local computer (running WAMP) as well as the live server:

function GetGlobalConnectionOptions()
{
    return array(
      'server' => 'localhost',
      'port' => '3306',
      'username' => 'sample_username',
      'password' => 'sample_password',
      'database' => 'sample_database'
);

I can connect to the live server database just fine. However, I'm not able to connect to the localhost database on my test computer. Here is the error I receive:

Could not connect to localhost: 
Access denied for user ''@'localhost' to database 'sample_database'

I don't understand how it won't work on my localhost. Also, I'm concerned that it is saying the user is ''@'localhost' instead of sample_username@localhost. Possibly that is part of the issue, but I'm stuck. Any suggestions would be greatly appreciated.

FYI I have both usernames set up in each database with all privileges granted.

Answer 1

In standard installations the users on localhost have to have explicit grants. So it does not suffice that user@% has access, it has to be user@localhost . As admin, enter grant all privileges on * to user@localhost identified by 'password'; flush privileges; grant all privileges on * to user@localhost identified by 'password'; flush privileges;
