Change The Database Name in phpMyAdmin

Change the database name through phpMyAdmin. This is an open-source application that is specially made for MySQL database management. It is a common tool for various web-hosting services.

This section will show how to use phpMyAdmin to change the WordPress database.

Edit Your Database

To start this method

  • login to the cPanel and locate phpMyAdmin.
  • In the left panel find the database in question and click on it.
  • Click the Operations

  • Enter the new name in the textbox under Rename Database.

  • Click the Go bottom at the bottom right.
  • Accept the change when prompted.

What it does is that it creates a new database with the new name and then imports the information from the old database to this new one.

This is the first part of the process. Now that the database has a new name the next step is to make sure that the wp-config.php file reflects these changes. Without updating the configuration file, the changes will not take effect.

Finding the wp-config.php File

As described above, the wp-config.php file is part of the setup of any self-hosted WordPress site. It does not come ready-made with WordPress. Rather, WordPress generates it upon installation. In fact, most web-based scripts have a similar configuration. These config files contain instructions on how to function and database information.

Access it by going to the website’s files. These files are accessible through the file manager from CPanel or using an FTP client.

Locating the WordPress Database Name

Right-click the wp-config.php file and select Edit or View. This action works both in the CPanel file manager and FTP client.

Inside the file, locate the value with the description DB_NAME. The text after this value is the name of the WordPress database. To find it fast use the search function. In Windows, this is with Ctrl+F and on a Mac computer CMD+F.

The code that contains the information looks like this:

//**MySQL settings - You can get this info from

your web host **//

/**MySQL database username */

define('DB_USER', 'yourusername');

/**MySQL database password */

define('DB_PASSWORD', 'this-is-your-password');

/**MySQL hostname */

define('DB_HOST', 'localhost');

/** Database Charset to use in creating

database tables. */

define('DB_CHARSET', 'utf8');

Usually, this section is one of the first things in the file. When the DB_NAME line is found, replace ‘your_db‘ with the new name that was saved through phpMyAdmin. Here, ‘your_db’ corresponds to the old name of the database. Do not forget to save the changes to the wp-config.php file.

Once inside the configuration file, also check the following values:


These are other important database details.

Instead of using the cPanel method, it is also possible to download the file through an FTP client and use a text editor to make the changes.

Assign a Database User

Now that the name has been adjusted and the wp-config.php configured, there is one more thing to do. Take a little bit of time to add a database user. This is done from cPanel.

  • Click MySQL Databases.

  • Scroll down and find Add a User to a Database
  • Add the user that was assigned to the new site to the newly created database. To know who that is, check the DB_USER line in the wp-config.php file. See the section above to learn how to do that.
  • In the drop-down box select the new database.
  • Click Add.
  • On the next page, select All Privileges.

  • Click Make Changes.
  • Reactivate all plugins
