因此，我的一个朋友和我正在ubuntu上同时使用xampp来连接彼此的网站，我们都创建了相同的php文件进行连接，所以我们使用了另一个的de
IP，但是它说一个错误

Warning: mysql_connect() [function.mysql-connect]: Host 'coke-laptop.local' is not allowed to connect to this MySQL server in /opt/lampp/htdocs/connection.php on line 2
Could not connect: Host 'coke-laptop.local' is not allowed to connect to this MySQL server

我们在connection.php文件上有以下代码：

<?php
$link = mysql_connect('10.100.161.37','root','');
if (!$link) {
    die('Could not connect: ' . mysql_error());
}
//echo 'Connected successfully';

$db_selected = mysql_select_db('Prueba', $link);
if (!$db_selected) {
    die ('Can\'t use Prueba : ' . mysql_error());
}

// This could be supplied by a user, for example
$firstname = 'fred';
$lastname  = 'fox';

// Formulate Query
// This is the best way to perform an SQL query
// For more examples, see mysql_real_escape_string()
$query = sprintf("SELECT * FROM Agencia");

// Perform Query
$result = mysql_query($query);

// Check result
// This shows the actual query sent to MySQL, and the error. Useful for debugging.
if (!$result) {
    $message  = 'Invalid query: ' . mysql_error() . "\n";
    $message .= 'Whole query: ' . $query;
    die($message);
}

// Use result
// Attempting to print $result won't allow access to information in the resource
// One of the mysql result functions must be used
// See also mysql_result(), mysql_fetch_array(), mysql_fetch_row(), etc.
while ($row = mysql_fetch_assoc($result)) {
    echo $row['ID'] . " ";
    echo $row['Nombre'] . "\n\r";
}

// Free the resources associated with the result set
// This is done automatically at the end of the script
mysql_free_result($result);
mysql_close($link);
?>

如果我们那样使用IP，则可以进入xampp正常的欢迎页面。
