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.
#rootユーザーのパスワード入力。インストール直後はrootユーザー未設定なのでそのままEnterで進みます。 Enter current password for root (enter for none): OK, successfully used password, moving on…
Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation.
#rootユーザーのパスワード設定確認。yを選択してパスワード設定します。
Set root password? [Y/n] y New password: Re-enter new password: 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.
#anonymousユーザーの削除確認。yを選択して削除します。
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.
#rootユーザーのリモートログイン確認。リモートからのログイン要件が無い場合はyを選択します。
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.
#testデータベースの削除確認。利用しない無い場合はyを選択し削除します。
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.
#testデータベースの削除確認。利用しない無い場合はyを選択し削除します。
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.
