安裝及設定 Edge SSO

Private Cloud v4.19.01 版

如要安裝及設定 Edge 單一登入 (SSO) 模組,您必須先產生兩組 TLS 金鑰和憑證。邊緣單一登入 (SSO) 模組使用傳輸層安全標準 (TLS) 來保護資訊傳輸作業的安全 作為 SAML IDP 握手流程的一部分。

建立 TLS 金鑰和憑證

下列步驟會建立自行簽署的憑證,或許適用於您的測試環境, 您通常需要為正式環境要求由 CA 簽署的憑證。

如何建立驗證及簽署金鑰和自行簽署憑證:

  1. sudo mkdir -p /opt/apigee/customer/application/apigee-sso/jwt-keys
  2. cd /opt/apigee/customer/application/apigee-sso/jwt-keys/
  3. sudo openssl genrsa -out privkey.pem 2048
  4. sudo openssl rsa -pubout -in privkey.pem -out pubkey.pem
  5. sudo chown apigee:apigee *.pem

建立金鑰和自行簽署的憑證 (不設定通關密語),以便與 SAML 通訊 IDP:

  1. sudo mkdir -p /opt/apigee/customer/application/apigee-sso/saml/
  2. cd /opt/apigee/customer/application/apigee-sso/saml/
  3. 使用通關密語產生私密金鑰:
    sudo openssl genrsa -aes256 -out server.key 1024
  4. 移除金鑰的通關密語:
    sudo openssl rsa -in server.key -out server.key
  5. 產生 CA 的憑證簽署要求:
    sudo openssl req -x509 -sha256 -new -key server.key -out server.csr
  6. 產生自行簽署的憑證 (有效期限為 365 天):
    sudo openssl x509 -sha256 -days 365 -in server.csr -signkey server.key -out selfsigned.crt
  7. sudo chown apigee:apigee server.key
  8. sudo chown apigee:apigee selfsigned.crt

如要在 Edge SSO 模組上啟用 TLS,請依照以下步驟操作: 將「SSO_TOMCAT_PROFILE」SSO_TOMCAT_PROFILE設為「SSL_TERMINATION」SSO_TOMCAT_PROFILE或 至 SSL_PROXY,您就無法使用自行簽署的憑證。您必須產生 由 CA 提供的憑證請參閱設定 apigee-sso: HTTPS 存取權

為 HTTP 安裝並設定邊緣單一登入 (SSO) 存取權

如要安裝邊緣單一登入 (SSO) 模組「apigee-sso」,必須按照相同程序操作 您當初用來安裝 Edge 的工具apigee-sso 是以 RPM 檔案表示, 這表示執行安裝的使用者必須是超級使用者,或者是擁有完整 sudo 的使用者 資源存取權詳情請參閱 Edge 安裝總覽

將設定檔傳送給安裝程式。設定檔的格式如下:

# Set to https if you enabled TLS on the management API.

SSO_SAML_IDP_METADATA_URL=https://dev-343434.oktapreview.com/app/exkar20cl/sso/saml/metadata

# by SSO_SAML_IDP_METADATA_URL. Necessary if URL uses a self-signed cert.

# The section "Create the TLS keys and certificates" above removes the passphrase,

如要安裝 Edge SSO 模組,請按照下列步驟操作:

  1. 登入 Management Server 節點。該節點應該已經 「apigee-service」已按照下列說明安裝: 安裝 Edge apigee-setup 公用程式

    請注意,您可以在其他節點上安裝邊緣單一登入 (SSO)。不過,該節點必須可以 透過通訊埠 8080 存取管理伺服器。

  2. 安裝 apigee-sso
    /opt/apigee/apigee-setup/bin/setup.sh -p sso -f configFile

    其中 configFile 是上述設定檔。

  3. 安裝 apigee-ssoadminapi.sh 公用程式, 管理 apigee-sso 模組的管理員和電腦使用者:
    /opt/apigee/apigee-service/bin/apigee-service apigee-ssoadminapi install
  4. 登出殼層再重新登入,以便新增 apigee-ssoadminapi.sh 延伸到路徑

指定中繼資料檔案而非網址

如果 IdP 不支援 HTTP/HTTPS 中繼資料網址,您可以使用中繼資料 XML 檔案來 設定邊緣單一登入 (SSO):

  1. 將 IDP 中的中繼資料 XML 內容複製到 Edge SSO 節點上的檔案。適用對象 例如,請將 XML 複製到:
    /opt/apigee/customer/application/apigee-sso/saml/metadata.xml
  2. 將檔案擁有權變更為 apigee:apigee:
    chown apigee:apigee /opt/apigee/customer/application/apigee-sso/saml/metadata.xml
  3. SSO_SAML_IDP_METADATA_URL 的值設為絕對檔案路徑:
    SSO_SAML_IDP_METADATA_URL=file:///opt/apigee/customer/application/apigee-sso/saml/metadata.xml

    您必須在檔案路徑前面加上「file://」,後面的絕對路徑是 根 (/)。
