Note:

Your hosting provider can enable or disable this interface for resellers in WHM's Edit Reseller Nameservers and Privileges interface (WHM >> Home >> Resellers >> Edit Reseller Nameservers and Privileges).

Overview

This interface allows server administrators to retrieve a list of MySQL and MariaDB database users, each user’s database, and which account owns each database user. The server administrator can use this interface to rename database users.

Database users

This interface provides a table of all of the database users on the server.

Click each column heading to sort the list by that column. Search for a particular user with the Search text box.

Rename a database user

To rename a database user, perform the following steps:

1. Click the pencil icon in the row that corresponds to the database user.
2. Enter the new name for the database user in the Rename to text box. To learn more about database username limits, click your database type:
   MySQL 5.6 and earlier

   MySQL 5.6 limits the database username to 16 characters. The system includes the database prefix (the first eight characters of the cPanel account’s username plus an underscore for a total of nine characters) in the character count for the username.

   For example:

   • A MySQL database with the db_ prefix allows usernames that contain up to 13 characters.
   • A MySQL database with the example_ prefix allows usernames that contain up to eight characters.
   MySQL 5.7 and later

   MySQL 5.7 limits the database username to 32 characters. The system includes the database prefix (the first sixteen characters of the cPanel account’s username plus an underscore for a total of seventeen characters) in the character count for the username.

   For example:

   • A MySQL database with the db_ prefix allows usernames that contain up to 29 characters.
   • A MySQL database with the example_ prefix allows usernames that contain up to 24 characters.
   MariaDB

   MariaDB limits the database username to 47 characters. The system includes the database prefix (all of the cPanel account’s username and an underscore character) in the character count for the username.

   For example:

   • A MariaDB database with the db_ prefix allows usernames that contain up to 44 characters.
   • A MariaDB database with the example_ prefix allows usernames that contain up to 39 characters.
3. Enter a new password for the user in the Set Password text box.
   Note:

   This step is optional.
4. Click Submit to confirm that you wish to rename the database user. To cancel the action, click Close.
