[MariaDB / MySQL] 초기 셋팅 + 원격접속 계정 생성

apt-get install mysql
apt-get install mariadb

 

 

1. 초기 보안설정

sudo mysql_secure_installation

Enter current password for root (enter for none): 
OK, successfully used password, moving on...

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

Set root password? [Y/n] Y ( 루트 패스워드 설정 여부 )

New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB 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 ( 익명 사용자 삭제 여부 )

 ... 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 ( root 계정의 원격 접속을 막을껀지 )

 ... skipping.

By default, MariaDB 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 데이터베이스 삭제 여부 )

 - 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 MariaDB
installation should now be secure.

Thanks for using MariaDB!

 

 

2. DB 생성 + 원격접속 계정생성 + 권한 추가

sudo mysql

# DB 생성
create database mydatabase default character set utf8;

use mysql;

# test 계정을 1234 비밀번호로 생성
create user 'test'@'%' identified by '1234';

grant all privileges on mydatabase.* to test@'%';

flush privileges;

exit

 

3. Mysql or MariaDB 설정파일에서 외부접속 허용

# mysql은 다른 설정파일임
sudo vim /etc/mysql/mariadb.conf.d/50-server.cnf

# bind-address를 주석처리
#bind-address            = 127.0.0.1

:wq

service mysql restart

 

4. 외부에서 접속해보기

 

 

※ DEFAULT PORT = 3306

※ 방화벽에서 3306 접근 허용시켜야함
