无法在Codeigniter中连接远程数据库服务器

Question

我正在尝试将mysql远程服务器连接到我的codeigniter应用程序。我的mysql服务器在其他机器上。所以我使用IP地址连接该服务器。但它显示我数据库错误

mysqli :: real_connect（）:( HY000 / 2002）：无主机路由

我不是因为php和mysql版本的兼容性与否。这是我的数据库连接代码，

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

    $db['default'] = array(
      'dsn' => '',
      'hostname' => '1XX.13X.1XX.XX',
      'username' => 'username',
      'password' => 'paswword',
      'database' => 'database_name',
      'dbdriver' => 'mysqli',
      'dbprefix' => '',
      'pconnect' => FALSE,
      'db_debug' => (ENVIRONMENT !== 'production'),
      'cache_on' => FALSE,
      'cachedir' => '',
      'char_set' => 'latin1',
      'dbcollat' => 'latin1_german2_ci',
      'swap_pre' => '',
      'encrypt' => FALSE,
      'compress' => FALSE,
      'stricton' => FALSE,
      'failover' => array(),
      'save_queries' => TRUE
   );

Answer 1

您没有对主机名进行任何更改，如下所示：

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

    $db['default'] = array(
      'dsn' => '',
      'hostname' => 'localhost', // Nothing change Here
      'username' => 'Your database Username',
      'password' => 'your Database Password',
      'database' => 'database_name',
      'dbdriver' => 'mysqli',
      'dbprefix' => '',
      'pconnect' => FALSE,
      'db_debug' => (ENVIRONMENT !== 'production'),
      'cache_on' => FALSE,
      'cachedir' => '',
      'char_set' => 'latin1',
      'dbcollat' => 'latin1_german2_ci',
      'swap_pre' => '',
      'encrypt' => FALSE,
      'compress' => FALSE,
      'stricton' => FALSE,
      'failover' => array(),
      'save_queries' => TRUE
   );
