  • STEP 4

On the left sidebar select the database you want to rename. In my case, I have a database named “testing” that I want to rename. After you click on the database, at the top of the page click on the Operations tab. Now scroll down a little bit to see the option “Rename database to” and, in the box just below it, type in your new database name. In my case I have typed MARIUSHOSTING. After that, click on Go at the right of the page. Now your database is renamed.

  • STEP 5

If everything went well, you will see the new database name in the left sidebar in phpMyAdmin.

  • STEP 6

If you run WordPress or any other applications, remember to change the wp-config.php file and, at DB_NAME, add the new database name you have previously created on STEP 4.

2 Synology phpMyAdmin rename database

  • STEP 7

The change will not be applied immediately in your NAS DSM. You need to wait 5 minutes then refresh the page or you will see an error that says: “Error establishing a database connection“. When the 5 minutes have passed, your site or application will be back online.

3 Synology phpMyAdmin rename database

Note: Before you rename any database in your Synology NAS, make a Backup of MariaDB 10 using the Hyper Backup package just in case something goes wrong.
: If you rename a database and this database has a user account with the same database name, your user account will be automatically deleted from the database. Log into your phpMyadmin / Users accounts / Add user account to create a new user account for the database.
Note: phpMyadmin is the graphical interface for MariaDB 10.
