Create Database Using mysqladmin
You would need special privileges to create or to delete a MySQL database. So assuming you have access to the root user, you can create any database using the mysql mysqladmin binary.
Example
Here is a simple example to create a database called TUTORIALS −
[root@host]# mysqladmin -u root -p create TUTORIALS Enter password:******
This will create a MySQL database called TUTORIALS.

<html>
<head><title>Creating MySQL Database</title></head>
<body>
<?php
$dbhost = ''localhost'';

$dbpass = ''root@123'';
$mysqli = new mysqli($dbhost, $dbuser, $dbpass);
if($mysqli→connect_errno ) {
printf("Connect failed: %s<br />", $mysqli→connect_error);
exit();
}
