mysql_secure_installation명령어를 알고 계시나요?

mysql 기본 보안 명령어이다.

mysql 초기 설치나 재설치 후에 기본적으로 보안 적용할 수 있는 명령어이지만, 이 명령어를 실행하시는 분을 거의 못 봤다ㅎ

사용법을 한번 살펴 보자.

# ./bin/mysql_secure_installation  ==>mysql홈디렉토리에서 실행해야 하니 주의하세요




NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!


In order to log into MySQL to secure it, we'll need the current
password for the root user.  If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):  ==> 현재 mysql 패스워드를 묻네요..전 초기 설치하여 그냥 엔터로 패스
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Set root password? [Y/n] y ==> mysql root 패스워드를 설정할지 묻는다. 당연히 yes
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!


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? [Y/n] y ==> 익명사용자  사용 삭제? 당연히 Yes
 ... Success!

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? [Y/n] y  ==> mysql 원격 접속 권한 제한. 일단 막고 보자
 ... 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? [Y/n] y ==>test DB를 삭제할 것인지 묻는다. 나중에 테스트 DB만들어도 되니 일단 삭제
 - 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.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...



All done!  If you've completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!

서버 엔지니어분들이라면 기본적인 보안은 갖추고 운영을 하였으면 좋겠다.
