How To Create or Delete a MySQL Database or User

Databases offer a method for easily managing large amounts of information over the web. 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:

  • cPanel username: lengthyusername
  • MySQL Database: lengthyu_wrdp1
  • MySQL Username: lengthyu_johndoe

This article discusses the different features of the MySQL Database. Please click the links below for the instructions.

This video will show you how effortless it is to create the database and the database user and assign that user to your new database. This is standard practice for anyone looking to install third-party programs that use MySQL databases manually.

Disclaimer: Your cPanel may look new, but the steps should be relatively the same.

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 your usernames when 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

Privileges determine how a user can interact with the database. For example, privileges will dictate whether or not the user can add and delete information.

  2. Next, use the DROP DATABASE command inside of mysql to delete the database. mysql> SHOW DATABASES LIKE "username_database"; +------------------------------+ | Database (username_database) | +------------------------------+ | username_database | +------------------------------+ 1 row in set (0.02 sec) mysql> DROP DATABASE username_database; Query OK, 0 rows affected (0.00 sec) mysql> SHOW DATABASES LIKE "username_database"; Empty set (0.02 sec) mysql>

Go to the DROP DATABASE Statement link for further information on this command.

How to drop one or multiple users at a Time

Using the MySQL statement DROP USER allows you to remove user accounts and their privileges from the database.

Syntax:

DROP USER ‘user’@’host’;
  • User: The user account you want to drop.
  • Host: The host server name of the user account. Format: ‘user_name’@’host_name’.

Example:

DROP USER ‘snappy01’@’localhost’;

To DROP multiple user accounts, follow this format:

DROP USER ‘snappy01’@’localhost’, ‘snappy02’@’localhost’;

How to grant Privileges in MySQL

To grant privileges to users in MySQL, you are first required to have the CREATE USER and GRANT privileges.

GRANT SELECT, INSERT, DELETE ON example_db TO ‘snappy02’@’localhost’;

How to view privileges in MySQL

To show existing users and their privileges in MySQL, run the command SHOW GRANT.

Syntax:

SHOW GRANTS FOR 'database_user'@'localhost';

Example:

SHOW GRANTS for ‘snappy02’@’localhost’;

Sample Output:

mysql> SHOW GRANTS FOR ‘snappy02’@'localhost';
