安装和配置 Apigee SSO

如需使用外部 IDP 安装和配置 Apigee SSO 模块,您必须执行以下操作:

  1. 创建密钥和证书
  2. 设置基本 Apigee SSO 配置:基础文件必须包含所有 SSO 配置通用的属性。
  3. 添加 IDP 专用配置属性:在配置文件中使用以下某个 IDP 专用配置属性块:
  4. 安装 Apigee SSO:安装 Apigee SSO 模块,并将配置文件传递给安装程序。

后续几个部分将介绍其中每个步骤。

创建密钥和证书

本部分介绍了如何创建自签名证书,这类证书可能适用于测试环境,但您应为生产环境使用由证书授权机构 (CA) 签名的证书。

如需创建用于签名以进行验证的密钥对,请执行以下操作

  1. 以 sudo 用户身份创建以下新目录:
    sudo mkdir -p /opt/apigee/customer/application/apigee-sso/jwt-keys
  2. 切换到新目录:
    cd /opt/apigee/customer/application/apigee-sso/jwt-keys/
  3. 使用以下命令生成私钥:
    sudo openssl genrsa -out privkey.pem 2048
  4. 使用以下命令从私钥生成公钥:
    sudo openssl rsa -pubout -in privkey.pem -out pubkey.pem
  5. 将输出 PEM 文件的所有者更改为“apigee”用户:
    sudo chown apigee:apigee *.pem

如需创建不带密码的密钥和自签名证书以与 IDP 通信,请执行以下操作

  1. 以 sudo 用户身份创建一个新目录:
    sudo mkdir -p /opt/apigee/customer/application/apigee-sso/idp/
  2. 切换到新目录:
    cd /opt/apigee/customer/application/apigee-sso/idp/
  3. 使用口令生成私钥:
    sudo openssl genrsa -out server.key 2048
  4. 从密钥中移除口令:
    sudo openssl rsa -in server.key -out server.key
  5. 为 CA 生成证书签名请求:
    sudo openssl req -x509 -sha256 -new -key server.key -out server.csr
  6. 生成有效期为 365 天的自签名证书:
    sudo openssl x509 -sha256 -days 365 -in server.csr -signkey server.key -out selfsigned.crt
  7. 将密钥和证书导出到密钥库:
    1. 将密钥和证书导出到 PKCS12 密钥库:
    2. sudo openssl pkcs12 -export -clcerts -in <certificate_path> -inkey <key_path> -out <keystore_path> -name <alias>

      参数:

      • certificate_path:第 6 步中创建的证书的路径。
      • key_path:第 3 步中生成的私钥的路径。
      • keystore_path:指向包含证书和私钥的新创建 PKCS12 密钥库的路径。
      • alias:用于引用密钥库中的密钥和证书对的别名。

      如需了解详情,请参阅 OpenSSL 文档

    3. (可选)将密钥和证书从 PKCS12 导出到 JKS 密钥库:
    4. sudo keytool -importkeystore -srckeystore <PKCS12_keystore_path> -srcstoretype PKCS12 
      -destkeystore <destination_keystore_path> -deststoretype JKS -alias <alias>

      参数:

      • PKCS12_keystore_path:指向第 7 步中创建的 PKCS12 密钥库的路径,其中包含证书和私钥。
      • destination_keystore_path:包含相同证书和密钥的新创建 JKS 密钥库的路径。
      • alias:用于 JKS 密钥库中的密钥和证书对的别名。

      如需了解详情,请参阅 keytool 文档

    5. 将输出密钥库文件的所有者更改为“apigee”用户:
      sudo chown apigee:apigee <keystore_file>
    6. 更新 silent.conf 中的以下属性:
    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

    如需在 Apigee SSO 模块上启用 TLS,请将 SSO_TOMCAT_PROFILE 设置为 SSL_TERMINATIONSSL_PROXY,但不能使用自签名证书。您必须通过 CA 生成证书。如需了解详情,请参阅配置 Apigee SSO 以实现 HTTPS 访问

    Apigee SSO 配置设置

    您必须先定义配置文件,然后才能安装 Apigee SSO 模块。在安装 Apigee SSO 模块时,您需要将此配置文件传递给安装程序。

    配置文件的格式如下:

    IP1=hostname_or_IP_of_apigee_SSO
    IP2=hostname_or_IP_of_apigee_SSO
    
    ## Management Server configuration.
    # Management Server IP address and port
    MSIP=$IP1
    MGMT_PORT=8080
    # Edge sys admin username and password as set when you installed Edge.
    ADMIN_EMAIL=opdk@google.com
    APIGEE_ADMINPW=Secret123
    # Set the protocol for the Edge management API. Default is http.
    # Set to https if you enabled TLS on the management API.
    MS_SCHEME=http
    
    ## Postgres configuration.

    # Set Tomcat TLS mode to DEFAULT to use HTTP access to apigee-sso.
    SSO_TOMCAT_PROFILE=DEFAULT
    SSO_PUBLIC_URL_SCHEME=http
    
    # SSO admin user name. The default is ssoadmin.
    SSO_ADMIN_NAME=ssoadmin
    # SSO admin password using uppercase, lowercase, number, and special chars.
    SSO_ADMIN_SECRET=Secret123
    
    # Enable the ability to sign an authentication request with SAML SSO.
    SSO_SAML_SIGN_REQUEST=y
    
    # Path to signing key and secret from Create the TLS keys and certificates above.
    SSO_JWT_SIGNING_KEY_FILEPATH=/opt/apigee/customer/application/apigee-sso/jwt-keys/privkey.pem

    SAML 单点登录配置属性

    如果您为 IDP 使用 SAML,请在配置文件(如上所定义)中使用以下配置属性块:

    ## 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,
    # see "Specifying a metadata file instead of a URL" below.

    # 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_PATH=/opt/apigee/customer/application/apigee-sso/saml/keystore.jks
    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 直接绑定配置属性

    如果您要为 IDP 使用 LDAP 直接绑定,请在配置文件中使用以下配置属性块,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 间接绑定配置属性

    如果您为 IDP 使用 LDAP 间接绑定,请在配置文件中使用以下配置属性块,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 服务器用于引用用户电子邮件地址的属性名称;例如“mail” SSO_LDAP_MAIL_ATTRIBUTE=LDAP_email_attribute

    安装 Apigee SSO 模块

    创建密钥并设置配置文件后,您可以安装 Apigee SSO 模块。

    如需安装 Apigee SSO 模块,请执行以下操作

    1. 登录管理服务器节点。该节点应已安装 apigee-service,如安装 Edge apigee-setup 实用程序中所述。

      或者,您也可以在其他节点上安装 Apigee SSO 模块。不过,该节点必须能够通过端口 8080 访问管理服务器。

    2. 通过执行以下命令安装并配置 apigee-sso
      /opt/apigee/apigee-setup/bin/setup.sh -p sso -f configFile

      其中,configFile 是您上面定义的配置文件。

    3. 安装用于管理 apigee-sso 模块的管理员用户和机器用户的 apigee-ssoadminapi.sh 实用程序:
      /opt/apigee/apigee-service/bin/apigee-service apigee-ssoadminapi install
    4. 退出 shell,然后重新登录,将 apigee-ssoadminapi.sh 实用程序添加到您的路径中。

    指定元数据文件,而不是网址

    如果您的 IDP 不支持 HTTP/HTTPS 元数据网址,您可以使用元数据 XML 文件来配置 Apigee SSO。

    如需使用元数据文件(而非网址)配置 Apigee SSO,请执行以下操作

    1. 将元数据 XML 的内容从 IDP 复制到 Apigee SSO 节点上的文件。例如,将 XML 复制到:
      /opt/apigee/customer/application/apigee-sso/saml/metadata.xml
    2. 将 XML 文件的所有权更改为“apigee”用户:
      chown apigee:apigee /opt/apigee/customer/application/apigee-sso/saml/metadata.xml
    3. SSO_SAML_IDP_METADATA_URL 的值设置为绝对文件路径:
      SSO_SAML_IDP_METADATA_URL=file:///opt/apigee/customer/application/apigee-sso/saml/metadata.xml

      您必须在文件路径前面添加“file://”,后跟根目录 (/) 的绝对路径。
