Migrating my local DB to a remote DB


I want to move my local DB that currently resides with my Nginx web server what I did so far was:

  • created a new DB cluster on DO
  • exported my DB and imported it to the remote one
  • I created a new droplet-based of my production server
  • copied the remote DB connection details to the wp-config.php(username, password, host, and port)

for some reason, I receive the infamous error message " Error establishing a database connection."

I am a bit newbie at this, so no doubt I am missing something critical here.

when I try to connect to the remote DB via terminal with the flag parameters on the staging droplet, it connects just fine, so I have no idea what the issue could be because I assume if I can connect with no problems, so it’s not a networking issue.

here’s my wp-config.php

// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'My_db');

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

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

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

/** Database Charset to use in creating database tables. */
define('DB_CHARSET', 'utf8mb4');

/** The Database Collate type. Don't change this if in doubt. */
define('DB_COLLATE', '');

Any idea’s what else I can check?

You need to make sure that your user is using mysql_native_password MySQL password as the default caching_sha2_password would not work with PHP and Wordpress.

To do that you can use the following query to create your new user:

CREATE USER 'wordpressuser'@your_server_ip IDENTIFIED WITH mysql_native_password BY 'password';
