    How to Create or Delete a MySQL Database or User

    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:

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

    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.

    Create a Database User
    1. Log into cPanel.
    2. Under Databases, click MySQL Databases.
    3. Click Jump to MySQL Users in the top-left corner of the page.
    4. Under Add New User, enter a username.MySQL Users Add New User
    5. Enter a password in the Password field.
      • For help generating a strong password, click the Generate Password button.
    6. Retype the password in the Password (Again) field.
    7. Click Create User.
    Delete a Database User
    1. Navigate to the Current Users section of MySQL Databases.
    2. In the Delete column, click the Delete next to the user you wish to delete.Delete Current Users

    Define a User’s Privileges and How Important They Are

    You need specific users to have permissions to perform website management tasks, like running queries or modifying databases. This is when we grant privileges. Privileges determine how a user is able to interact with the database. For example, privileges will dictate whether or not the user can add and delete information.

    Assign Privileges to Database User
    1. Log into cPanel.
    2. Under Databases, click MySQL Databases.
    3. Under Add User to Database, select a user from the User drop-down menu.
    4. From the Database drop-down menu, select the database you wish to allow the user access to.Add User To Database
    5. Click Add.
    6. From the MySQL Account Maintenance screen, select the privileges you wish to grant the user or select ALL PRIVILEGES.Add User TO Database
    7. Click Make Changes.
    Unassign a User from a Database
    1. Navigate to the Current Databases section of MySQL Databases.
    2. Locate the database you wish to modify.
    3. In the Privileged Users column for that database, click the X next to the user you wish to delete.Priveleged Users

    Using the Database

    Now that you can create databases and users, and assign appropriate privileges, you can use the following articles as references in editing and connecting to your databases.

    Delete a Database Without Using cPanel

    The steps below are done using SSH. If you know how to use it, follow these steps; however, if you need help, contact us via phone or Live Chat for assistance.

    1. Make a backup of the database with SSH using the command line below. Use your cPanel password.
      username@domain [~] # mysqldump --password username_database > username_database.db
      Enter password:  (cPanel Password)
      username@domain [~] #
      
    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 DROP DATABASE Statement link for further information on this command.

    Drop One or Multiple Users at a Time

    Using the MySQL statement DROP USER allows you to remove user accounts and also 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’;
    Granting Privileges in MySQL

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

    Syntax:

    GRANT permission1, permission2 ON database_name TO 'user'@'localhost';

    Example:

    GRANT SELECT, INSERT, DELETE ON example_db TO ‘snappy02’@’localhost’;
    
    
    Viewing 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';
    +------------------------------------------------------------------+
    | Grants for snappy02@localhost |
    +------------------------------------------------------------------+
    | GRANT USAGE ON *.* TO `snappy02`@`localhost` |
    | GRANT SELECT, INSERT, UPDATE ON `example_db`.* TO `snappy02`@`localhost` |
