신기술을 테스트해보기 위해 23ai를 개인 VM에 설치했습니다.
rpm으로 설치시에 간단히 preinstall.rpm으로 설치전 설정을 자동으로 해주고, install.rpm으로 편하게 설치를 해주네요.
OS는 linux 8이상 설치가능합니다.
설치OS : centos 9
DB 버전 : Oracle 23ai free
설치 url : https://www.oracle.com/kr/database/free/get-started/

1.(root에서 수행) rpm을 다운받아 VM에 넣은 후 preinstall부터 설치합니다.
[root@ysbae tmp]# rpm -ivh oracle-database-preinstall-23ai-1.0-2.el9.x86_64.rpm

에러가 발생시에는 아래 명령어로 필요 라이브러리를 설치해줍니다.
yum 이 아니라 dnf로 명령어가 변경되었네요.
[root@ysbae tmp]# dnf -y install xorg-x11-utils

2.oracle database rpm 설치
해당 rpm으로 엔진설치를 완료했습니다.
커맨드로도 나오듯이 /etc/sysconfig/oracle-free-23ai.conf 를 수행하여 DB를 생성해야 합니다.
저는 default로 설치할 예정이기 때문에 설정값 건드리지 않고 바로 DB를 설치하겠습니다.

DB 기동/중지는 root로 수행합니다.
--중지
/etc/init.d/oracle-free-23ai stop
--기동
/etc/init.d/oracle-free-23ai start설치는 금방되네요. 23ai는 어떤기능들이 있는지 하나씩 테스트해볼 재미가 있겠습니다.
