Question about MySQL Host & wp-config.php

Hi there.

Just a quick question regards a database that I am migrating from an old shared hosting setup, to a new shiny London-based VPS.

These are the 4 definitions within the wp-config.php file which connect the database.

/** The name of the database for WordPress */
define('DB_NAME', 'eg');

/** MySQL database username */
define('DB_USER', 'eg');

/** MySQL database password */
define('DB_PASSWORD', 'eg');

/** MySQL hostname */
define('DB_HOST', 'localhost');

My question, when connecting to a newly imported database (imported via PHPMyAdmin) should the DB_Host be localhost, or the IP address of the Droplet? What are the differences?

Thanks a lot.

The DB_HOST variable should be set to localhost. Unless you setup another Droplet and want to run mysql on it and connect to it from your current Droplet. localhost means your own Droplets local network (not exposed to the internet) and it maps to 127.0.0.1 (so localhost = 127.0.0.1).

Great, thank you.
