4. MariaDB를 재시작했으면 이번에는 설치한 데이터베이스를 mysql_secure_installation 명령어를 이용해 초기화합니다. 초기화하는 과정에서 root 패스워드 설정 여부, anonymous 사용자 삭제 여부, 원격에서 root 계정으로 데이터베이스 접속을 막을지 여부, test 데이터베이스 삭제 여부, 설정 내용 적용 여부를 물어봅니다. 패스워드는 앞에서 미리 설정한 대로 사용하면 되고, 나머지는 모두 y를 입력합니다. 이 책에서는 패스워드를 openstack으로 설정했습니다.

root@controller:~# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we’ll need the current password for the root user. If you’ve just installed MariaDB, and you haven’t set the root password yet, the password will be blank, so you should just press enter here.

Enter current password for root (enter for none): 패스워드 입력 Enter OK, successfully used password, moving on…

Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation.

Set root password? [Y/n] y New password: 패스워드 입력 Enter Re-enter new password: 패스워드 입력 Enter Password updated successfully! Reloading privilege tables.. … Success!

By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment.

Remove anonymous users? [Y/n] y … Success!

Normally, root should only be allowed to connect from ‘localhost’. This ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y … Success!

By default, MariaDB comes with a database named ‘test’ that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment.

Remove test database and access to it? [Y/n] y - Dropping test database… … Success! - Removing privileges on test database… … Success!

Reloading the privilege tables will ensure that all changes made so far will take effect immediately.

Reload privilege tables now? [Y/n] y … Success!

Cleaning up…

All done! If you’ve completed all of the above steps, your MariaDB installation should now be secure.

Thanks for using MariaDB!
