MySQL installation

First, update the system package and repository lists:

sudo apt-get -y update && sudo apt-get -y dist-upgrade

Add the MariaDB repository:

curl -sS https://downloads.mariadb.com/MariaDB/mariadb_repo_setup | sudo bash

Install MariaDB:

sudo apt-get -y install mariadb-server

Next, start the client using the following command:

mysql -u root -p

Select the MySQL system database:

USE mysql;

Create the first user:

CREATE USER 'spacecore'@'localhost' IDENTIFIED BY '123456';

Now create a database:

CREATE DATABASE server;

Use the following two commands to grant the user access to the database:

GRANT ALL PRIVILEGES ON server.* TO 'spacecore'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;

If you need to connect to MySQL from a host other than localhost, edit /etc/mysql/my.cnf and find the bind-address line so that it looks as follows:

#bind-address = 127.0.0.1

Restart MySQL:

service mysql-server restart
