How to Create or Delete a MySQL Database or User Print

  • 0

Databases offer a method for managing large amounts of information over the web easily. They are necessary to run many web-based applications, such as bulletin boards, content management systems, and online retail shops.

Note: Resellers can create accounts with usernames up to 16 characters long. Please note that MySQL Databases and Usernames will only include the first 8 characters. For example:

1. cPanel username: lengthyusername

2. MySQL Database: lengthyu_wrdp1

3. MySQL Username: lengthyu_johndoe

Create or Delete a Database User

What is a MySQL User, and Why is it Important?

The MySQL user is a record in the MySQL server created for authentication purposes. This is different from the usernames you use in logging into Windows or even in your cPanel/WHM. Setting up a MySQL user provides more security to your website’s databases as you can assign permissions to each user. Aside from you, the website’s owner, you do not wish to grant just any user all access to your database.

After creating the database, you will need to create a user and assign privileges. Please note that MySQL user accounts must be created separately from mail and web administrator accounts.

Define a User's Privileges and How Important They Are

2. Look for the Databases section, then click MySQL Databases.
