CodeIgniter setting up routing properly - php

Question

I'm trying to setting up my codeigniter routing to make an authentication form for an admin panel, but the routing is not working. I'm a beginner with CodeIgniter and I think I'm missing something.
In my server I put the CodeIgniter fiels inside folder in my root directory, so it can be accessed like this:
/localhost/ci
In my config.php I set my base url and remove the index page to remove index.php:
$config['base_url'] = 'http://localhost/ci/';
$config['index_page'] = '';
Also I have edited the .htaccess to remove the index.php like CodeIgniter documentation says, so it looks like this:
RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]
Now, my routes config file looks like this. I set my default page and a route to my Auth controller:
$route['default_controller'] = 'auth';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
$route['auth/login'] = "auth/login";
This is my Controller:
class Auth extends CI_Controller {
function __construct() {
parent::__construct();
// load libraries
}
function index() {
if (! $this->ion_auth->logged_in()) {
// redirect them to the dashboard page
redirect(base_url('auth/login'), 'refresh');
} else {
// show the dashboard page
redirect(base_url('dashboard'), 'refresh');
}
}
function login() {
$this->load->view('login');
}
When I enter in the web-browser http://localhost/ci/ it redirects me to http://localhost/ci/auth/login, but then a 404 Not Found error ir raised. What am I missing? I'm a bit confused at this point, thanks.

Try changing your .htaccess from:
RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]
To
RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /ci/index.php/$1 [L]
