设置现有CodeIgniter的数据库连接错误

Question

I downloaded the CodeIgniter project from server and I want to run it in my localhost, I got an error when I run it. Does anyone know what is the problem? I used MAMP on Mac.

Here is my db error:

ErrorException [ Fatal Error ]: Unable to connect to your database server using the provided settings. / Filename: core/Loader.php / Line Number: 346

Here is database.php

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

$active_group = ENVIRONMENT;
$active_record = TRUE;

$db['development']['hostname'] = 'localhost';
$db['development']['username'] = 'fake';
$db['development']['password'] = 'fake';
$db['development']['database'] = 'bmgr';
$db['development']['dbdriver'] = 'mysqli';
$db['development']['dbprefix'] = '';
$db['development']['pconnect'] = TRUE;
$db['development']['db_debug'] = TRUE;
$db['development']['cache_on'] = FALSE;
$db['development']['cachedir'] = '';
$db['development']['char_set'] = 'utf8';
$db['development']['dbcollat'] = 'utf8_general_ci';
$db['development']['swap_pre'] = '';
$db['development']['autoinit'] = TRUE;
$db['development']['stricton'] = FALSE;

$db['staging']['hostname'] = 'localhost';

Answer 1

You are not connected to MySQL Server at all. Please make sure that MySQL is installed on your machine.Second , check if the MySQL Service is running. Third , make sure about access information that you have filled on Database.php file.

Answer 2

no offense, but just for my curiosity is your database located on the same server? I see you use 'localhost' but database may also be on a different machine. I would double check user/password using terminal (use MySQL from prompt, connect, use 'bmgr', select from a table). If this works it means your file is not correctly edited. If it doesn't you may be pointing to the wrong machine and/or you have a firewall issue and/or user permission issue
