我将我的网页从旧系统移到新系统，现在我在连接数据库时遇到问题。版本是：Mysql 5.1.67 和 phpMyadmin 3.4.3.2。问题出在哪里？

在网站上：

警告：mysqli::mysqli() [mysqli.mysqli]: (HY000/2002): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) in /home/do031500第 13 行 /www_root/lib/database.inc.php 无法连接到数据库服务器

数据库.inc.php：

class CDatabase {

public  $Connected  = false;
private $Mysqli;
public  $Result;

// Connect to database server
function Connect() {
    global $DatabaseSupport;
    if ($DatabaseSupport) {
    $this->Mysqli = new mysqli(dbServer, dbUser, dbPassword, dbDatabase);
    if (mysqli_connect_errno()) {
        $this->Connected    = false;
        Terminate("Could not connect to database server");
        } else { 
        $this->Connected    = true;
        $this->Mysqli->autocommit(FALSE);
        $this->Mysqli->set_charset("utf8");
    }
    }
}

// Disconnect from server
function Disconnect() {
    if ($this->Connected) {

    }
}

        if (!$this->Result)

最初的想法是由于您的连接变量之一。您是否仔细检查过您是否拥有所有新服务器的信息？服务器、端口、用户名、密码、数据库、表？
