Question

我有一个奇怪的问题......

使用Codeigniter我在测试域和托管包上重新设计了我的网站，今天我已将所有文件复制到我的其他域和托管包，更改了我的数据库配置（它们100％正确） - 而且我得到这个错误：

发生数据库错误

无法使用提供的设置连接到数据库服务器。

文件名：core / Loader.php

行号：346

我不应该更改任何文件中的任何其他设置值，因为它仍然在我的测试域上工作，而不是在另一个文件中... - 是否有任何其他配置设置我忘了切换到主'application / config / database.php'

| DATABASE CONNECTIVITY SETTINGS
| -------------------------------------------------------------------
| This file will contain the settings needed to access your database.
|
| For complete instructions please consult the 'Database Connection'
| page of the User Guide.
|
| -------------------------------------------------------------------
| EXPLANATION OF VARIABLES
| -------------------------------------------------------------------
|
|   ['hostname'] The hostname of your database server.
|   ['username'] The username used to connect to the database
|   ['password'] The password used to connect to the database
|   ['database'] The name of the database you want to connect to
|   ['dbdriver'] The database type. ie: mysql.  Currently supported:
                 mysql, mysqli, postgre, odbc, mssql, sqlite, oci8
|   ['dbprefix'] You can add an optional prefix, which will be added
|                to the table name when using the  Active Record class
|   ['pconnect'] TRUE/FALSE - Whether to use a persistent connection
|   ['db_debug'] TRUE/FALSE - Whether database errors should be displayed.
|   ['cache_on'] TRUE/FALSE - Enables/disables query caching
|   ['cachedir'] The path to the folder where cache files should be stored
|   ['char_set'] The character set used in communicating with the database
|   ['dbcollat'] The character collation used in communicating with the database
|                NOTE: For MySQL and MySQLi databases, this setting is only used
|                as a backup if your server is running PHP < 5.2.3 or MySQL < 5.0.7
|                (and in table creation queries made with DB Forge).
|                There is an incompatibility in PHP with mysql_real_escape_string() which
|                can make your site vulnerable to SQL injection if you are using a
|                multi-byte character set and are running versions lower than these.
|                Sites using Latin-1 or UTF-8 database character set and collation are unaffected.
|   ['swap_pre'] A default table prefix that should be swapped with the dbprefix
|   ['autoinit'] Whether or not to automatically initialize the database.
|   ['stricton'] TRUE/FALSE - forces 'Strict Mode' connections
|                           - good for ensuring strict SQL while developing
|
| The $active_group variable lets you choose which connection group to
| make active.  By default there is only one group (the 'default' group).
|
| The $active_record variables lets you determine whether or not to load
| the active record class
*/

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

$db['default']['hostname'] = '79.170.40.242';
$db['default']['username'] = 'xxxxxx';
$db['default']['password'] = 'Xxxxxx';

$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;

Answer 1

您的数据库连接失败。您的数据库服务器似乎是远程的，因此请查看以下两项：

1-号码3306（mysql端口）的传入端口访问

2-访问所有外来传入主机的mysql用户（参见更多：mysql adding user manual）

Codeigniter数据库连接错误
