使用php codeigniter連接到遠程服務器數據庫

Question

我在連接到遠程服務器中的數據庫時遇到問題。 代碼是/config/database.php如下：

$active_group = 'default';
$active_group = 'main';
$active_record = TRUE;

$db['default']['hostname'] = 'localhost';
$db['default']['username'] = 'root';
$db['default']['password'] = '';
$db['default']['database'] = 'local_server';
$db['default']['dbdriver'] = 'mysql';
$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;


$db['main']['hostname']='xxx.xx.xx.xx';
$db['main']['username']='user';
$db['main']['password'] ='pwd';
$db['main']['database'] = 'database1';
$db['main']['dbdriver'] = 'mysql';
$db['main']['dbprefix'] = '';
$db['main']['pconnect'] = TRUE;
$db['main']['db_debug'] = TRUE;
$db['main']['cache_on'] = FALSE;
$db['main']['cachedir'] = '';
$db['main']['char_set'] = 'utf8';
$db['main']['dbcollat'] = 'utf8_general_ci';
$db['main']['swap_pre'] = '';
$db['main']['autoinit'] = TRUE;
$db['main']['stricton'] = FALSE;

在/system/database/DB_driver.php中。 我已經將pconnect更改為true var $ pconnect = TRUE;

從控制器說學生，我嘗試按照以下代碼連接遠程服務器數據庫，說“ database1”：

public function check_main()
    {
        $this->load->database('database1','TRUE');
    }

我收到以下錯誤：

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

Filename: C:\xampp\htdocs\student_attendance\system\database\DB_driver.php

Line Number: 124

In the remote server, % wildcard is given for "Remote Database Access Hosts"

Answer 1

$active_group = 'default';

$active_group = 'main';

$active_record = TRUE;


try to change above code to

$active_group = 'default';

$active_record = TRUE;
