安裝並設定 Apigee 單一登入 (SSO)

如要使用外部 IDP 安裝及設定 Apigee 單一登入 (SSO) 模組,您必須執行下列操作:

  1. 建立金鑰和憑證
  2. 設定 Apigee 基礎單一登入設定基礎檔案必須包含所有 SSO 設定的共用屬性。
  3. 新增 IdP 專屬設定屬性:在設定檔中使用下列任一 IdP 專屬設定屬性區塊:
  4. 安裝 Apigee SSO安裝 Apigee SSO 模組,並將設定檔傳遞至安裝程式。

我們會在後續章節中說明每個步驟。

建立金鑰和憑證

本節說明如何建立自行簽署的憑證,這類憑證可能適用於測試環境,但您應在實際工作環境中使用由憑證授權單位 (CA) 簽署的憑證。

如何建立用於簽署驗證的金鑰組:

  1. 以 sudo 使用者身分建立以下新目錄:
    sudo mkdir -p /opt/apigee/customer/application/apigee-sso/jwt-keys
  2. 變更至新的目錄:
    cd /opt/apigee/customer/application/apigee-sso/jwt-keys/
  3. 使用下列指令產生私密金鑰:
    sudo openssl genrsa -out privkey.pem 2048
  4. 使用下列指令,從私密金鑰產生公開金鑰:
    sudo openssl rsa -pubout -in privkey.pem -out pubkey.pem
  5. 將輸出 PEM 檔案的擁有者變更為「apigee」使用者:
    sudo chown apigee:apigee *.pem

如要建立金鑰和自行簽署的憑證 (不含密碼字串),以便與 IDP 通訊:

  1. 以 sudo 使用者身分建立新目錄:
    sudo mkdir -p /opt/apigee/customer/application/apigee-sso/idp/
  2. 變更至新的目錄:
    cd /opt/apigee/customer/application/apigee-sso/idp/
  3. 使用通關密語產生私密金鑰:
    sudo openssl genrsa -out server.key 2048
  4. 從金鑰中移除密碼短語:
    sudo openssl rsa -in server.key -out server.key
  5. 為 CA 產生憑證簽署要求:
    sudo openssl req -x509 -sha256 -new -key server.key -out server.csr
  6. 產生有效期限為 365 天的自行簽署憑證:
    sudo openssl x509 -sha256 -days 365 -in server.csr -signkey server.key -out selfsigned.crt
  7. 將金鑰和憑證匯出至 KeyStore:
    1. 將金鑰和憑證匯出至 PKCS12 金鑰庫:
    2. sudo openssl pkcs12 -export -clcerts -in <certificate_path> -inkey <key_path> -out <keystore_path> -name <alias>

      參數:

      • certificate_path在步驟 6 中建立的憑證路徑。
      • key_path在步驟 3 中產生的私密金鑰路徑。
      • keystore_path新建 PKCS12 金鑰庫的路徑,其中包含憑證和私密金鑰。
      • alias用於參照 KeyStore 中金鑰和憑證組合的別名。

      詳情請參閱 OpenSSL 說明文件

    3. (選用) 將金鑰和憑證從 PKCS12 匯出至 JKS KeyStore:
    4. sudo keytool -importkeystore -srckeystore <PKCS12_keystore_path> -srcstoretype PKCS12 
      -destkeystore <destination_keystore_path> -deststoretype JKS -alias <alias>

      參數:

      • PKCS12_keystore_path步驟 7 中建立的 PKCS12 金鑰庫路徑,其中包含憑證和私密金鑰。
      • destination_keystore_path新建 JKS 金鑰庫的路徑,其中包含相同的憑證和金鑰。
      • alias在 JKS 鍵值儲存庫中,用於金鑰和憑證組合的別名。

      詳情請參閱 Keytool 說明文件

    5. 將輸出 KeyStore 檔案的擁有者變更為「apigee」使用者:
      sudo chown apigee:apigee <keystore_file>
    6. 請在 silent.conf 中更新下列屬性:
    7. # Path to your keystore  
      SSO_SAML_SERVICE_PROVIDER_KEYSTORE_PATH=/opt/apigee/customer/application/apigee-sso/saml/keystore.p12  
      
      # Keystore password
      SSO_SAML_SERVICE_PROVIDER_KEYSTORE_PASSWORD=Secret123
      
      # Alias within keystore that stores the key and certificate  
      SSO_SAML_SERVICE_PROVIDER_KEYSTORE_ALIAS=service-provider-cert  
      
      # [Optional] Only specify if you are using something other than JKS. Values could be PKCS12 or BCFKS  
      SSO_SAML_SERVICE_PROVIDER_KEYSTORE_TYPE=JKS

    如要在 Apigee 單一登入模組上啟用 TLS,請將 SSO_TOMCAT_PROFILE 設為 SSL_TERMINATIONSSL_PROXY,這樣就無法使用自行簽署的憑證。您必須透過 CA 產生憑證。詳情請參閱「為 HTTPS 存取權設定 Apigee SSO」一文。

    Apigee 單一登入 (SSO) 設定

    您必須先定義設定檔,才能安裝 Apigee 單一登入 (SSO) 模組。安裝 Apigee 單一登入 (SSO) 模組時,您會將此設定檔傳遞給安裝程式。

    設定檔的格式如下:

    IP1=hostname_or_IP_of_apigee_SSO
    IP2=hostname_or_IP_of_apigee_SSO

    SAML 單一登入 (SSO) 設定屬性

    如果您要為 IdP 使用 SAML,請在設定檔 (如上所定義) 中使用以下設定屬性區塊:

    ## SAML Configuration Properties
    # Insert this section into your base configuration file, as described previously.
    
    # Name of SAML IDP. For example, okta or adfs.
    SSO_SAML_IDP_NAME=okta
    # Text displayed on the SSO sign-in page after being redirected by either the New or Classic Edge UI for SAML logins.
    # Note: Installing SSO does not depend on the Edge UI or which version of the UI you are using.
    SSO_SAML_IDP_LOGIN_TEXT="Please log in to your IDP"
    
    # The metadata URL from your IDP.
    # If you have a metadata file, and not a URL,

    # Determines whether to skip TLS validation for the URL specified
    # by SSO_SAML_IDP_METADATA_URL.
    # This is necessary if the URL uses a self-signed certificate.
    # The default value is "n".
    SSO_SAML_IDPMETAURL_SKIPSSLVALIDATION=n
    
    # Keystore configuration details
    # [Optional] Only specify KEYSTORE_TYPE if you are using something other than JKS. Values could be PKCS12 or BCFKS.

    SSO_SAML_SERVICE_PROVIDER_KEYSTORE_PASSWORD=Secret123
    SSO_SAML_SERVICE_PROVIDER_KEYSTORE_ALIAS=service-provider-cert
    SSO_SAML_SERVICE_PROVIDER_KEYSTORE_TYPE=JKS
    
    # Requires that SAML responses be signed by your IDP.
    # This property is enabled by default since release 4.50.00.05.
    SSO_SAML_SIGNED_ASSERTIONS=y

    LDAP 直接繫結設定屬性

    如果您為 IdP 使用 LDAP 直接繫結,請在設定檔中使用以下設定屬性區塊,如上例所示:

    ## LDAP Direct Binding configuration
    # Insert this section into your base configuration file, as described previously.
    
    # The type of LDAP profile; in this case, "direct"
    SSO_LDAP_PROFILE=direct
    
    # The base URL to which SSO connects; in the form: "ldap://hostname_or_IP:port
    SSO_LDAP_BASE_URL=LDAP_base_URL
    
    # Attribute name used by the LDAP server to refer to the user's email address; for example, "mail"
    SSO_LDAP_MAIL_ATTRIBUTE=LDAP_email_attribute
    
    # Pattern of the user's DN; for example: =cn={0},ou=people,dc=example,dc=org
    # If there is more than one pattern, separate with semicolons (";"); for example:
    # =cn={0},ou=people,dc=example,dc=org;=cn={0},ou=people,dc=example,dc=com
    SSO_LDAP_USER_DN_PATTERN=LDAP_DN_pattern

    LDAP 間接繫結設定屬性

    如果您要為 IdP 使用 LDAP 間接繫結,請在設定檔中使用下列設定屬性區塊,如上例所示:

    ## LDAP Indirect Binding configuration
    # Insert this section into your base configuration file, as described previously.
    
    # Type of LDAP profile; in this case, "indirect"
    SSO_LDAP_PROFILE=indirect
    
    # Base URL to which SSO connects; in the form: "ldap://hostname_or_IP:port
    SSO_LDAP_BASE_URL=LDAP_base_URL
    
    # DN and password of the LDAP server's admin user
    SSO_LDAP_ADMIN_USER_DN=LDAP_admin_DN
    SSO_LDAP_ADMIN_PWD=LDAP_admin_password
    
    # LDAP search base; for example, "dc=example,dc=org"
    SSO_LDAP_SEARCH_BASE=LDAP_search_base
    
    # LDAP search filter; for example, "cn={0}"
    SSO_LDAP_SEARCH_FILTER=LDAP_search_filter
    # LDAP 伺服器用來參照使用者電子郵件地址的屬性名稱,例如「mail」 SSO_LDAP_MAIL_ATTRIBUTE=LDAP_email_attribute

    安裝 Apigee 單一登入 (SSO) 模組

    建立金鑰並設定設定檔後,即可安裝 Apigee SSO 模組。

    安裝 Apigee SSO 模組的方式:

    1. 登入管理伺服器節點。該節點應已安裝 apigee-service,如安裝 Edge apigee-setup 公用程式一文所述。

      或者,您可以在其他節點上安裝 Apigee 單一登入模組。不過,該節點必須能夠透過通訊埠 8080 存取管理伺服器。

    2. 執行下列指令,安裝及設定 apigee-sso
      /opt/apigee/apigee-setup/bin/setup.sh -p sso -f configFile

      其中 configFile 是您在前面定義的設定檔。

    3. 安裝 apigee-ssoadminapi.sh 公用程式,用於管理 apigee-sso 模組的管理員和機器使用者:
      /opt/apigee/apigee-service/bin/apigee-service apigee-ssoadminapi install
    4. 請登出殼層,然後重新登入,將 apigee-ssoadminapi.sh 公用程式新增至路徑。

    指定中繼資料檔案,而非網址

    如果您的 IdP 不支援 HTTP/HTTPS 中繼資料網址,您可以使用中繼資料 XML 檔案設定 Apigee 單一登入 (SSO)。

    如要使用中繼資料檔案,而非網址來設定 Apigee 單一登入 (SSO):

    1. 將 IDP 中的中繼資料 XML 內容複製到 Apigee SSO 節點的檔案中。例如,將 XML 複製到:
      /opt/apigee/customer/application/apigee-sso/saml/metadata.xml
    2. 將 XML 檔案的擁有權變更為「apigee」使用者:
      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方加上「file://」,接著是從根目錄 (/) 開始的絕對路徑。
