Why is my pagination in codeigniter not working? (404 not found) - codeigniter

Question

I already follow the step and tutorial. But it's not working.
I already follow tutorial from internet step by step. But it always show 404 page not found when I go to second page
This is my controller:
public function index()
{
$this->load->library('pagination');
$config['base_url'] = base_url().'index.php/blog';
$config['uri_segment'] = 2;
$config['per_page'] = 2;
$config['total_rows'] = $this->mod_blog->getAllData()->num_rows();
$this->pagination->initialize($config);
// $page = ($this->uri->segment(2)) ? ($this->uri->segment(2) - 1) : 0;
$page = $this->uri->segment(2);
$data = array(
'data' => $this->mod_blog->getData($config['per_page'],$page)->result(),
'pagination' => $this->pagination->create_links()
);
$this->load->view('layout/header');
$this->load->view('layout/sidebar');
$this->load->view('admin/blog',$data);
$this->load->view('layout/footer');
}
This is my Model:
function getData($limit,$start){
$this->db->select('*');
$this->db->from('berita');
$this->db->join('admin','admin.id_admin = berita.id_admin');
$this->db->limit($limit,$start);
$this->db->order_by('id_berita','desc');
return $this->db->get();
}
function getAllData(){
$this->db->select('*');
$this->db->from('berita');
$this->db->join('admin','admin.id_admin = berita.id_admin');
$this->db->order_by('id_berita','desc');
return $this->db->get();
}

Whoops, I found my mistake.
It's in the
$config['base_url'] = base_url().'index.php/blog';
You must point the config['base_url'] to your baseUrl/controllerName/functionName. So, I changed it into.
$config['base_url'] = base_url().'index.php/blog/index';
And then I adjust my Uri segment into 3
$config['uri_segment'] = 3;
$page = $this->uri->segment(3);
