我在计算机上有一个Codeigniter项目，它作为公共访问运行。但是它使用的MySql数据库只能通过localhost访问。当我运行应用程序时，我得到了
A Database Error Occurred
Unable to connect to your database server using the provided settings.
Filename: core/Loader.php
Line Number: 346
我按照here提到的说明，但我仍然收到同样的错误
Try
1. print_r($params) and print_r($active_record);
2. if the $params are still correct then simplify $active_record
3. echo mysql_error();
4. $db[‘default’][‘db_debug’] = true/false
5. $db[‘default’][‘stricton’] = true/false;
[编辑]
我已将参数设置为
$db['default']['hostname'] = 'mysql12.freehostia.com';
$db['default']['username'] = 'username';
$db['default']['password'] = 'password';
$db['default']['database'] = 'myDB';
$db['default']['dbdriver'] = 'mysql';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = false;
$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'] = '';
