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
haven't set the root password yet, you should just press enter here.

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

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

You already have your root account protected, so you can safely answer 'n'.
[Unix_Socket] 認証に切り替えるか否か
Switch to unix_socket authentication [Y/n] y
… skipping.
You already have your root account protected, so you can safely answer 'n'.
MariaDB root パスワードを設定するか否か
Change the root password? [Y/n] y
… skipping.
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.
匿名ユーザーは削除する
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 のリモートログインは無効とする
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.
テストデータベースは削除する
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.
特権情報をリロードする
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.

The roundcube package must have a database installed and configured |
| before it can be used. This can be optionally handled with |
| dbconfig-common. |
| |
| If you are an advanced database administrator and know that you want to |
| perform this configuration manually, or if your database has already |
| been installed and configured, you should refuse this option. Details |
| on what needs to be done should most likely be provided in |
| /usr/share/doc/roundcube. |
| |
| Otherwise, you should probably choose this option. |
| |
| Configure database for roundcube with dbconfig-common? |
| |
|
<Yes> <No>
