使用Codeigniter连接到（Linux）Centos上的MS SQL

Question

I like to connect an MS SQL database on (Linux)Centos with Codeigniter. Just installed the Centos Linux. Apache/ftp works.

But know i want to connect to an internal SQL server in my Linux machine trough Codeigniter. I already installed with Yum mssql-php but when i trying to connect in Codeigniter it says "Unable to connect to your database server using the provided settings.".

My question is what i need to do on my Centos machine to connect my Codeigniter PHP with an internal SQL 2008 database?

My Codeigniter setting are:

$db['default']['hostname'] = '***\***,1433';
$db['default']['username'] = '***';
$db['default']['password'] = '***';
$db['default']['database'] = '**';
$db['default']['dbdriver'] = 'mssql'; 
$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;

On an XAMPP Windows machine this setup works well bu using sqlsrv. But that is only supported on a Windows machine..

Screen of my PHPinfo shows this:

You need to install php-mssql extension on your linux machine.

Step 1: Install needed respositories

Remi Dependency on CentOS 6 and Red Hat (RHEL) 6

rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

Remi Dependency on CentOS 5 and Red Hat (RHEL) 5

rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-5.rpm

Step 2: Install the extension

yum --enablerepo=remi php-mssql

---

Step 3: Enable extension

Edit your php.ini and load the php_mssql library and restart your Apache web server.

Answer 2

It is currently working for my by installing mssql at the Linux machine. Codeigniter has the following configuration:

$db['sql']['dbdriver'] = 'mssql';

$db['sql']['dbprefix'] = '';

$db['sql']['pconnect'] = TRUE;

$db['sql']['db_debug'] = FALSE;

$db['sql']['cache_on'] = FALSE;

$db['sql']['cachedir'] = '';

$db['sql']['char_set'] = 'utf8';

$db['sql']['dbcollat'] = 'utf8_general_ci';

$db['sql']['swap_pre'] = '';

$db['sql']['autoinit'] = TRUE;

$db['sql']['stricton'] = FALSE;

PHP configuration:

FreetDs config on Linux server

It is important to configure the connection on the Linux machine in the FreetDS config. After that you will see in the phpinfo that there is an Active connection an Codeigniter can connect with the SQL database.

Codeigniter_project\\application\\config\\database.php

 $active_group = 'default';
    $query_builder = TRUE;

$db['default'] = array(
    'dsn'   => '',
    'hostname' => 'localhost',
    'username' => 'admin',
    'password' => 'Admin@321',
    'database' => 'xxxx',
    'dbdriver' => 'mysqli',
    //'dbdriver' => 'mysql',
    'dbprefix' => '',
    'pconnect' => FALSE,
    'db_debug' => (ENVIRONMENT !== 'production'),
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array(),
    'save_queries' => TRUE
);


$db['posdb']['hostname'] = 'xxx.xxx.xxx.xxx:1433';
//$db['posdb']['port'] = 1433; // or the port you configured on step 6
$db['posdb']['username'] = 'sa';
$db['posdb']['password'] = 'myself@123';
$db['posdb']['database'] = '

Blockquote

new';

$db['posdb']['dbdriver'] = 'mssql';
$db['posdb']['dbprefix'] = '';
$db['posdb']['pconnect'] = TRUE;
$db['posdb']['db_debug'] = FALSE;
$db['posdb']['cache_on'] = FALSE;
$db['posdb']['cachedir'] = '';
$db['posdb']['char_set'] = 'utf8';
$db['posdb']['dbcollat'] = 'utf8_general_ci';
$db['posdb']['swap_pre'] = '';
$db['posdb']['autoinit'] = TRUE;
$db['posdb']['stricton'] = FALSE;

Consider posdb be the second database which is going to connect with remote mssql at 2012

To get this in Controller is

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Contrller_name extends CI_Controller{     

    public function __construct()
    {
      parent::__construct();     
      $this->load->model('my_model');
      $this->load->library('session');    
    }
    public function connet(){       
        $connnet =  $this->my_model->connet();
        echo "<pre>";
        print_r($connnet);
        //var_dump($connnet);
    }
}   
?>

Now at model

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

class My_model extends CI_Model
{
     function __construct()
     {         
          parent::__construct();
          $this->load->helper('date');
          $this->pos_db= $this->load->database('posdb', TRUE);  // loading secondary remote database 

     }
     function connet(){        
        $sql ="SELECT TOP 10 * FROM dbo.Party";
    $query = $this->pos_db->query($sql);
    $result = $query->result_array();
    return $result;
     }

}?>

This is worked for me most of times
