▼ 설치 안내 및 기본 셋팅

Securing the MySQL server deployment.

Connecting to MySQL using a blank password.

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?

## 암호 검증 여부시 → y
Press y|Y for Yes, any other key for No: y

 

 - 암호 생성시 암호 복잡도 지정 

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

## 암호 생성시 암호 복집도 지정 → 지정 후 root계정에 대한 암호 생성
Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 0

 

 - 기본 제공하는 익명 유저(anonymous user) 삭제 여부 → 삭제

Skipping password set for root as authentication with auth_socket is used by default.
If you would like to use password authentication instead, this can be done with the "ALTER_USER" command.
See https://dev.mysql.com/doc/refman/8.0/en/alter-user.html#alter-user-password-management for more information.

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.

## anonymous user 제거 여부 → 제거

Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.

 

 - 외부로부터 접근 허용 여부(기본 : root 계정은 localhost에서만 접근 허가) → 외부로부터 막으려면 y 입력

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) : y

 

 

 - test 데이터베이스 접근 및 삭제여부

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
Success.

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
Success.
