4. 이번에는 데이터베이스 접근을 위한 초기화를 합니다. mysql_secure_installation 명령어를 실행하면 MariaDB의 Root 패스워드를 설정할 수 있습니다. 나머지 불필요한 anonymous user나 테스트 데이터베이스 등은 삭제합니다. 원격에서는 Root 계정을 이용해 접속하는 것을 차단하도록 설정할 수도 있습니다. 여기서는 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): 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!
