By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL 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? (Press y|Y for Tes, any other key for No) : y
#匿名ユーザーを削除しますか？ yを入力
Success.

Normally, root should only be allowed to connect from
‘localhost’. This ensures that someone connect guess at
the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
#rootのリモートアクセスを無効にしますか？ yを入力
Success.

By default, MySQL 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? (Press y|Y for Yes, any other key for No) : y
#テストデータベースを削除しますか？ yを入力
 - Dropping test database…
Success.

 - Removing privileges on test database…

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

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
#特権テーブルを再読込しますか？ yを入力
Success.

All done!
