Question

I have been using CI just fine using the MySQL driver. I want to use the MySQL driver instead, but as soon as I change it (just add the ‘i’ at the end of MySQL, and added the port number) I get the following error message

A Database Error Occurred

Unable to connect to your database server using the provided settings.

Filename: core/Loader.php

Line Number: 232

my setting look like this:

$db['default']['hostname'] = $hostname;
$db['default']['username'] = $username;
$db['default']['password'] = $password;
$db['default']['database'] = $database;
$db['default']['dbdriver'] = 'mysqli';
$db['default']['port']     = "3306";  
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE; 

where
$hostname = 'localhost';
$username = 'myusernamegoeshere';
$password = 'mypasswordgoeshere';
$database = 'mydatabasenamegoeshere'; 

I’m Using:

CI 2.0.2 php 5.3.4 Apache/2.2.17 (Unix) mysql 5.5.13 mysql.default_port 3306

Am I doing anything wrong?

Thank you,

For me the issue was in the php.ini file. The property mysql.default_socket was pointing to file in a non-existent directory. The property was pointing to /var/mysql/mysql.sock but in OSX, the file was located in /tmp/mysql.sock.

Once I updated the entry in php.ini and restarted the webserver, the issue was resolved.
