VALIDATE PASSWORD COMPONENT can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD component?

# ゆるいパスワード(abc/passwdなど)を登録したい場合はn
Press y|Y for Yes, any other key for No: y

There are three levels of password validation policy:

LOW    Length >= 8
MEDIUM Length >= 8, numeric, mixed case, and special characters
STRONG Length >= 8, numeric, mixed case, special characters and dictionary                  file

# ログインパスワードの強度指定。

Please set the password for root here.

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

# 匿名ユーザを削除しますか?
Remove anonymous users? (Press y|Y for Yes, any other key for No) : y

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

# リモートログインを許可しない設定にしますか?
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y

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

# テスト用データベースを削除してもいいですか?
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
 - Dropping test database...

 - Removing privileges on test database...

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

# 権限関連の設定テーブルをリロードしますか?
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y

All done!
