Private Cloud용 Edge v4.19.01
외부 역할 매핑을 사용하면 자체 그룹 또는 역할을 역할 기반 액세스 제어에 매핑할 수 있습니다. Apigee Edge에서 생성된 (RBAC) 역할 및 그룹 이 기능은 프라이빗 클라우드입니다.
기본 요건
- 전역 시스템 관리자가 있는 Apigee Private Cloud 시스템 관리자여야 합니다. 사용자 인증 정보를 사용하여 이 구성을 수행할 수 있습니다.
- Apigee Edge Private Cloud 설치의 루트 디렉터리를 알고 있어야 합니다. 이
기본 루트 디렉터리는
/opt입니다.
단계별 설정 예
를 참조하세요. 이 도움말을 참고하세요. 역할 매핑
기본 구성
외부 역할 매핑은 기본적으로 사용 중지되어 있습니다.
외부 역할 매핑 사용 설정
외부 역할 매핑을 사용 설정하려면 다음 안내를 따르세요.
- 다음 구성을 완료하려면 먼저 다음 구성을 완료하는 Java 클래스를 만들어야 합니다.
ExternalRoleMapperServiceV2 인터페이스를 구현하고
관리 서버 클래스 경로:
/opt/apigee/edge-management-server/lib/thirdparty/
이 구현에 대한 자세한 내용은 ExternalRoleMapperImpl 정보 샘플 구현을 참조하세요.
- Apigee Edge 관리 서버에 로그인한 다음 관리 서버 프로세스를 중지합니다.
/opt/apigee/apigee-service/bin/apigee-service edge-management-server stop
/opt/apigee/customer/application/management-server.properties열기 코드를 작성합니다 이 파일이 없으면 새로 만듭니다.- 속성 파일을 수정하여 다음과 같이 설정합니다.
# The user store to be used for authentication. # Use "externalized.authentication" for LDAP user store. # Note that for authorization, we continue to use LDAP. # See Enabling external authentication more on enabling external auth. conf_security_authentication.user.store=externalized.authentication #Enable the external authorizations role mapper. conf_security_externalized.authentication.role.mapper.enabled=true conf_security_externalized.authentication.role.mapper.implementation.class=com.customer.authorization.impl.ExternalRoleMapperImpl
management-server.properties파일을 저장합니다.management-server.properties이 Apigee 사용자의 소유인지 확인하세요.chown apigee:apigee /opt/apigee/customer/application/management-server.properties
- 관리 서버를 시작합니다.
/opt/apigee/apigee-service/bin/apigee-service edge-management-server start
외부 승인 사용 중지
외부 승인을 사용 중지하려면 다음 단계를 따르세요.
/opt/apigee/customer/application/management-server.properties열기 코드를 작성합니다 파일이 없으면 새로 만듭니다.- 인증 사용자 저장소를 'ldap'로 변경합니다.
conf_security_authentication.user.store=ldap
- 이 속성을 'false'로 설정합니다.
conf_security_externalized.authentication.role.mapper.enabled=false
- 관리 서버를 다시 시작합니다.
/opt/apigee/apigee-service/bin/apigee-service edge-management-server start
ExternalRoleMapperImpl 정보 샘플 구현
앞서 외부 역할 매핑 사용 설정에서 설명한 security.properties 구성 파일에서 다음 행을 확인합니다.
externalized.authentication.role.mapper.implementation.class=com.customer.authorization.impl.ExternalRoleMapperImpl
이 클래스는 ExternalRoleMapperServiceV2 인터페이스를 구현하며, 필수입니다. 해야 할 일 각 그룹을 반영하는 이 클래스의 자체 구현을 만듭니다. 완료되면 컴파일된 클래스를 JAR에 넣고 이 JAR을 관리 서버의 클래스 경로에 넣습니다.
/opt/apigee/edge-management-server/lib/thirdparty/<ph type="x-smartling-placeholder">
클래스가 구현되어 있다면 클래스 이름을 지정하고 원하는 대로 패키징할 수 있습니다. ExternalRoleMapperServiceV2를 클래스 경로에서 액세스할 수 있으며 management-server.properties 구성 파일
다음은 ExternalRoleMapperImpl 클래스의 샘플 구현입니다.
