How to Manage MySQL Databases and Users in cPanel

How to manage MySQL databases and users in cPanel/phpMyAdmin is a free software tool written in PHP, intended to handle the administration of MySQL over the Web. phpMyAdmin supports a wide range of operations on MySQL and MariaDB. Frequently used operations (managing databases, tables, columns, relations, indexes, users, permissions, etc) can be performed via the user interface, while you still have the ability to directly execute any SQL statement.

This article describes how to use cPanel to manage MySQL databases and users. You can add, modify, and delete databases and users, as well as manage user database permissions.

Managing Database Users

To access MySQL databases, you must first create at least one user. The following procedures describe how to manage MySQL database users using cPanel.

Creating a database user

To create a MySQL database user, follow these steps:

• Log in to cPanel.
  If you do not know how to log in to your cPanel account,
• In the DATABASES section of the cPanel home screen, click MySQL® Databases:
• Under Add New User, in the Username text box, type the MySQL username.
• In the Password text box, type the user password.
• In the Password (Again) text box, retype the user password.
  You can click Password Generator and cPanel generates a random, strong password for you.
• Click Create User. cPanel creates the database user.

Changing a user’s password

You can change a database user’s password. You may want to do this for security reasons (changing passwords periodically is a good security practice), or you may need to do this if you forget the password.

To change a MySQL user’s password, follow these steps:

• Log in to cPanel.
  If you do not know how to log in to your cPanel account,
• In the DATABASES section of the cPanel home screen, click MySQL® Databases:
• Under Current Users, locate the user for which you want to change the password, and then click Change Password.
• In the Password and Password (Again) text boxes, type the new password.
  You can click Password Generator and cPanel generates a random, strong password for you.
• Click Change Password. The new password takes effect immediately.

Renaming a user

To rename a MySQL user, follow these steps:

• Log in to cPanel.
  If you do not know how to log in to your cPanel account,
• In the DATABASES section of the cPanel home screen, click MySQL® Databases:
• Under Current Users, locate the user that you want to rename, and then click Rename.
• In the New name text box, type the new name, and then click Proceed. cPanel renames the user.

Deleting a user

When you delete a user, the user and its database permissions are deleted.

MANAGING DATABASES

After you create a database user, you are ready to create a database and associate the user with the new database.

Creating a database

• Click Create Database. cPanel creates the database.
  When you create a database, your username is prefixed to the database name. For example, if your username is a username, and you create a database named database, the actual MySQL database name is username_database.

Adding a user to a database

To add a MySQL user to a database, follow these steps:

• Log in to cPanel.
  If you do not know how to log in to your cPanel account
• In the DATABASES section of the cPanel home screen,

• Click Add.
• Select the checkboxes to grant the user-specific privileges, or select the ALL PRIVILEGES checkbox to grant the user all permissions to the database.
• Click Make Changes. cPanel adds the user to the database.

Checking and repairing a database

You can check MySQL databases for errors or possible corruption. If a database check reveals problems, you can repair the database as well.

To check and repair a database, follow these steps:

• Log in to cPanel.
  If you do not know how to log in to your cPanel account
• In the DATABASES section of the cPanel home screen,

  • Click the Repair Database.

Revoking privileges from a database user

When you revoke a database user’s privileges, the user can no longer access the database. To do this, follow these steps:

• Log in to cPanel.
  If you do not know how to log in to your cPanel account
• In the DATABASES section of the cPanel home screen,
• Under Current Databases, locate the user for which you want to revoke privileges, and then click the trash can icon.
