To create a MySQL Database, log in to cPanel and click on MySQL Databases icon from the DATABASES section.
Enter the database name that you want on the box and click Create Database button.
Your MySQL database will be created with the username_ automatically added before the name. For example, if you choose the name “mydatabase” and your cPanel username is abCd, then your newly created database name would be abCd_mydatabase
You can now also access your database from phpMyAdmin if you need to.
