借助外部角色映射,您可以将自己的群组或角色映射到基于角色的访问权限控制 在 Apigee Edge 上创建的 (RBAC) 角色和群组。此功能仅适用于 Edge, Private Cloud
前提条件
- 您必须是具有全局系统管理员的 Apigee Private Cloud 系统管理员 凭据执行此配置。
- 您需要知道 Apigee Edge 私有云安装的根目录。通过
默认根目录为
/opt
。
分步设置示例
请参阅 Apigee 社区论坛上的这篇文章,了解有关设置 External 角色映射。
默认配置
外部角色映射默认处于停用状态。
启用外部角色映射
如需启用外部角色映射,请执行以下操作:
- 在完成以下配置之前,您必须创建一个 Java 类,
实现 ExternalRoleMapperServiceV2 接口,并将您的实现包含在
管理服务器类路径:
/opt/apigee/edge-management-server/lib/thirdparty/
如需详细了解此实现,请参阅 About the ExternalRoleMapperImpl 实现示例。
- 登录您的 Apigee Edge 管理服务器,然后停止管理服务器进程:
/opt/apigee/apigee-service/bin/apigee-service edge-management-server stop
- 打开“
/opt/apigee/customer/application/management-server.properties
” 文本编辑器中。如果此文件不存在,请创建它。 - 修改属性文件以进行以下设置:
# 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
- 保存
management-server.properties
文件。 - 确保
management-server.properties
归 apigee 用户所有:chown apigee:apigee /opt/apigee/customer/application/management-server.properties
- 启动管理服务器:
/opt/apigee/apigee-service/bin/apigee-service edge-management-server start
停用外部授权
如需停用外部授权,请执行以下操作:
- 打开“
/opt/apigee/customer/application/management-server.properties
” 文本编辑器中。如果该文件不存在,请创建该文件。 - 将身份验证用户存储区更改为“ldap”:
conf_security_authentication.user.store=ldap
- 将此属性设置为“false”:
conf_security_externalized.authentication.role.mapper.enabled=false
- 重启管理服务器:
/opt/apigee/apigee-service/bin/apigee-service edge-management-server start
ExternalRoleMapperImpl 简介 实现示例
在之前启用外部角色映射部分所述的 security.properties 配置文件中,请注意以下行:
externalized.authentication.role.mapper.implementation.class=com.customer.authorization.impl.ExternalRoleMapperImpl
此类实现了 ExternalRoleMapperServiceV2 接口,是必需的。您需要 根据相应的组创建该类的实现。完成后, 将编译的类放入 JAR 中,并将该 JAR 放入管理服务器的类路径中:
/opt/apigee/edge-management-server/lib/thirdparty/<ph type="x-smartling-placeholder">
您可以随意命名该类和打包该类,只要它能够实现即可 ExternalRoleMapperServiceV2 可在类路径中访问,可在 management-server.properties 配置文件。
