Okay, next steps are to create a database and database user for Ghost.
Type sudo mysql
and you’ll see a different prompt. This is because you are using MySQL and have left the BASH command-line. You’ll need to replace <password> with your password; create a new one for this.
create database boringdigital_com;
create user 'user_boringdigital_com'@'localhost' identified by '<password>';
grant all privileges on boringdigital_com.* to 'user_boringdigital_com'@'localhost';
flush privileges;
quit;
Please let me know how this goes.
