CentOS 8에서 MariaDB 10.4 버전의 설치 방법을 알아보고, 실습을 통해 쉽게 적용하고 사용할 수 있습니다.


실습 환경

  • 운영 체제(OS) : CentOS 8
  • root 계정으로 실행
  • IP 설정 및 인터넷이 가능한 환경

참고 사항

  • DNF 와 YUM 명령어 둘다 사용 가능합니다.
  • 이 글에서는 DNF 명령어를 사용합니다.

MariaDB 저장소 등록하기

cat 명령을 사용해서 Mariadb.repo 파일을 생성합니다.

[cat << EOF > /etc/yum.repos.d/MariaDB.repo #MariaDB 10.4 CentOS repository list #http://downloads.mariadb.org/mariadb/repositories/ [mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.4/centos8-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1 EOF]

MariaDB 저장소 파일 내용 확인하기

Mariadb.repo 파일 내용을 확인합니다.

[cat /etc/yum.repos.d/MariaDB.repo]

[root@RunIT ~]# cat /etc/yum.repos.d/MariaDB.repo #MariaDB 10.4 CentOS repository list #http://downloads.mariadb.org/mariadb/repositories/ [mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.4/centos8-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1

Boost-program-options 설치하기

  1. MariaDB-server 설치 시 galera-4 패키지가 먼저 설치되어야 합니다.
  2. galera-4 설치 시 libboost_program_options.so 라이브러리가 필요합니다.
  3. 종속성 해결을 위해 Boost-program-options 패키지를 먼저 설치합니다.

[dnf install boost-program-options -y]

MariaDB 서비스 등록하기

systemctl 을 통해 서비스 등록하게 되면 부팅 시 자동으로 시작됩니다.

MariaDB root 비밀번호 및 보안 설정하기

mysql_secure_installation 명령을 실행하여 root 초기 패스워드를 설정할 수 있습니다.

[mysql_secure_installation]

[root@RunIT ~]# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and haven't set the root password yet, you should just press enter here. Enter current password for root (enter for none): << Enter 키를 누릅니다.  기존에 설정한 암호가 없습니다. OK, successfully used password, moving on... Setting the root password or using the unix_socket ensures that nobody can log into the MariaDB root user without the proper authorisation. You already have your root account protected, so you can safely answer 'n'. Switch to unix_socket authentication [Y/n] N << 패스워드 인증을 활성화 하기 위해 소켓 인증을 사용하지 않습니다. ... skipping. You already have your root account protected, so you can safely answer 'n'. Change the root password? [Y/n] Y << MariaDB root 암호를 설정합니다. New password: << root 암호 입력 Re-enter new password: << root 암호 재입력 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 << Anonymous 계정 삭제합니다. ... 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 << 원격에서 root 로그인을 금지합니다. ... Success! 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 데이터베이스를 삭제합니다. - 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 << 권한 테이블을 다시 불러옵니다. ... 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!
