PhpMyAdmin is a unique and popular web-based application/ administrative tool used to administer MySQL servers and databases. This tutorial explains how to create a new database and a new user to access that database on a MySQL Server using phpMyAdmin.

You will require a root or DBA user login to the MySQL server, or a user login with permission to create new databases.You will need to have access to an instance of phpMyAdmin appropriately configured to administrate the MySQL server.If you require a dedicated web server running MySQL and phpMyAdmin.

Using phpMyAdmin Version 3.5.1

Type your phpMyAdmin URL using your Internet Web Browser, and login using your root or dba user login as shown.

The section that relates to the users GLOBAL privileges are privileges you want to assign to this user which apply to ALL databases on the server. It is recommended that you do NOT assign these permissions unless you know exactly what you are doing. It is far more secure to assign seperate user logins to each piece of software or website that will require access to only a particular database. Therefore leave this section BLANK, and then click the Add User button.

After the user is created, you can see it listed on the Users page. Click Edit Privileges to assign access to a specific database.

Click GO after selecting the relevant privileges.

If you click on the users Edit Privileges option now, you will see that new privileges for the specific database are now listed as belonging to the user.

Click the Logout option in the top left corner, and test your new user login with phpMyAdmin.
