15 To uninstall if you do not want to use openGauss:

gs_uninstall --delete-data

원클릭 환경 정리

openGauss 제거가 완료된 후 환경에 openGauss를 재배포할 필요가 없는 경우 스크립트를 실행할 수 있습니다.

gs_postuninstall은 openGauss 서버의 환경 정보를 정리합니다. openGauss 환경 정리는 링에 대한 답입니다.

환경 준비 스크립트 gs_preinstall에서 만든 설정을 정리합니다.

전제 조건

(1) openGauss의 제거가 성공적으로 실행되었습니다.

(2) 루트 사용자만 gs_postuninstall 명령을 실행할 수 있습니다.

openGauss 서버에 루트 사용자로 로그인합니다. 압축을 푼 디렉토리를 입력하십시오:/soft/script 경로.

./gs_postuninstall -U omm -X/soft/clusterconfig.xml --delete-user --delete-group
