DigitalOcean doesn’t offer the possibility to create a managed instance of a MariaDB database, so you may want to set up your own instance on a DigitalOcean droplet.
For the sake of this tutorial, we will create a Ubuntu 22.10 server. We will add our SSH keys to the server to allow us to SSH into the droplet in order to setup mariadb.
Follow the steps in this DigitalOcean guide to start the MariaDB server on the droplet:
1. SSH into the droplet
2. Install/start MariaDB server and restrict server access.
3. Setup a database with mock data (optional).
Open the MariaDB prompt:
Run the following SQL command to create a mock database:
You will likely want to configure your server to allow for remote connections to your database.
Create a MariaDB user which will have access via a remote server. In this case we will use the Basedash IP address in case you’d like to allow Basedash to connect to your MariaDB database. From the mariadb, prompt, run the following command:
💡 You can use % instead of an IP address if you want the user to have remote access from any host.
Next, grant the user all privileges on all databases:
💡 You may want to only grant all privileges for the user on a specific database, which can be done as follows:
Where application.* grants all privileges to the admin user on all database tables in the application database.
Flush privileges to make the changes take effect:
Next, we will need to configure the firewall on the droplet to allow connections to port 3306 (default mariadb port) from our remote IP (in this example it is 22.214.171.124):
If you want to let the firewall allow connections from any IP address, you can run the following command:
Reload the firewall to have the changes take effect:
The last thing to do is to change some of the default configuration specified by mariaDB. Modify the file found at /etc/mysql/mariadb.conf.d/50-server.cnf so that the line that contains the bind-address setting is set to 0.0.0.0 instead of the default 127.0.0.1.
That way we will allow connections other than localhost (i.e. 127.0.0.1) to connect to our mariadb database.
Restart mariadb using sudo systemctl restart mariadb.service. You should now be able to connect remotely to the mariadb instance.
Here’s how the credentials look like when trying to connect to the mariadb database from Basedash:
