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?

Press y|Y for Yes, any other key for No: no
Please set the password for root here.

New password:

설정 2. 유저 사용 여부

• YES: 접속시 -u 옵션 필요함
• NO: 접속시 -u 옵션 필요없이 접근 가능

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 Yes, any other key for No) : yes
Success.

 

설정 3. 원격 접속

• YES: 원격 접속 불가능
• NO: 원격 접속 가능

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? (Press y|Y for Yes, any other key for No) : no

 ... skipping.

 

설정 4. 테스트 데이터베이스 사용 여부

• YES: 제거
• NO: 유지

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) : yes
 - Dropping test database...
Success.

 - Removing privileges on test database...
Success.

 

설정 5: 변경 내용을 테이블에 적용 여부

• YES: 적용
• NO: 미적용

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) : yes
Success.

All done!
