php - mysqli::real_connect(): (HY000/2002): 实时连接被拒绝

Question

我使用 PHP、Mysql 和 Codeignater 版本 3 创建了一个网站。然后将其托管在 iPage 上。当我实时上传时，我会更改配置文件。

$db['default'] = array(
    'dsn'   => '',
    'hostname' => '66.96.147.118',
    'username' => 'bit_root',
    'password' => 'root',
    'database' => 'bit_shilp',
    'dbdriver' => 'mysqli',
    '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
);

我使用 codeignater 版本 3。在本地它运行良好。但是在现场它给出了一个错误。

请查看此链接 http://bitshilp.com/BitShilp/index.php/home

它给出了这样的错误:

A PHP Error was encountered

谢谢。

如果 MySQL 服务器已启动并正在运行 - 那么这看起来像是一些传输(例如防火墙)问题。第一步是尝试下面的 telnet 命令 - 如果它显示错误，则问题与 PHP 或 MySQL 无关:

telnet 66.96.147.118 3306 

(成功会打印mysql版本+一些随机字符)
