To install MySQL Server on Linux call:
      sudo apt install mysql-server-8.0
      sudo mysql_secure_installation

If mysql_secure_installation does not offer to set root password, you can call:
      sudo mysql 
      ALTER USER 'root'@'localhost' IDENTIFIED BY 'new password' PASSWORD EXPIRE NEVER;

To create a new user dedicated to NodeActa server call:
      sudo mysql 
      CREATE USER 'NODEACTA'@'localhost' IDENTIFIED BY 'new password' PASSWORD EXPIRE NEVER;
      GRANT ALL PRIVILEGES ON *.* TO 'NODEACTA'@'localhost' WITH GRANT OPTION;
      FLUSH PRIVILEGES;
