Edge for Private Cloud v4.18.01
安装和配置 Edge SSO 模块需要您首先生成两组 TLS 密钥和证书。在 SAML 握手过程中,边缘 SSO 模块与 SAML IDP 使用传输层安全协议 (TLS) 来保护信息的传输。
注意:默认情况下,可在安装该模块的节点的端口 9099 上通过 HTTP 访问 Edge SSO 模块。您可以在 Edge SSO 模块上启用 TLS。为此,您必须创建第三组供 Tomcat 用于支持 TLS 的 TLS 密钥和证书。如需了解详情,请参阅配置 apigee-sso 以访问 HTTPS。
创建 TLS 密钥和证书
以下步骤将创建自签名证书,自签名证书可能适合您的测试环境,但通常需要 CA 为生产环境签名的证书。
如需创建验证和签名密钥以及自签名证书,请执行以下操作:
- > sudo mkdir -p /opt/apigee/customer/application/apigee-sso/jwt-keys
- > cd /opt/apigee/customer/application/apigee-sso/jwt-keys/
- > sudo openssl genrsa -out privkey.pem 2048
- > sudo openssl rsa -pubout -in privkey.pem -out pubkey.pem
- > sudo chown apigee:apigee *.pem
如需创建与 SAML IDP 通信所需的密钥和自签名证书(无密码),请执行以下操作:
- > sudo mkdir -p /opt/apigee/customer/application/apigee-sso/saml/
- > cd /opt/apigee/customer/application/apigee-sso/saml/
- 使用以下密码生成私钥:
> sudo openssl genrsa -aes256 -out server.key 1024 - 移除密钥中的口令:
> sudo openssl rsa -in server.key -out server.key - 为 CA 生成证书签名请求:
> sudo openssl req -x509 -sha256 -new -key server.key -out server.csr - 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 - > sudo chown apigee:apigee server.key
- > sudo chown apigee:apigee selfsigned.crt
如果您想在 Edge SSO 模块上启用 TLS(通过将 SSO_TOMCAT_PROFILE 设置为 SSL_TERMINATION 或 SSL_PROXY),则不能使用自签名证书。您必须从 CA 生成证书。如需了解详情,请参阅配置 apigee-sso 以访问 HTTPS。
安装并配置 Edge SSO 以实现 HTTP 访问
如需安装 Edge SSO 模块 apigee-sso,您必须使用安装 Edge 时所用的过程。由于 apigee-sso 由 RPM 文件表示,因此执行安装的用户必须是 root 用户或者具有完整 sudo 访问权限的用户。如需了解详情,请参阅 Edge 安装概览。
将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_management_server IP2=hostname_or_ip_of_UI_and_apigge_sso ## Management Server configuration. MSIP=$IP1 MGMT_PORT=8080 # Edge sys admin username and password as set when you installed Edge. ADMIN_EMAIL=opdk@google.com APIGEE_ADMINPW=Secret123 # Set the protocol for the Edge management API. Default is http. # Set to https if you enabled TLS on the management API. MS_SCHEME=http ## Postgres configuration. PG_HOST=$IP1 PG_PORT=5432 # Postgres username and password as set when you installed Edge. PG_USER=apigee PG_PWD=postgres # apigee-sso configuration. SSO_PROFILE="saml" # Externally accessible IP or DNS name of apigee-sso. SSO_PUBLIC_URL_HOSTNAME=$IP2 # Default port is 9099. If changing, set both properties to the same value. SSO_PUBLIC_URL_PORT=9099 SSO_TOMCAT_PORT=9099 # 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 # 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 SSO_JWT_VERIFICATION_KEY_FILEPATH=/opt/apigee/customer/application/apigee-sso/jwt-keys/pubkey.pem # Name of SAML IDP. For example, okta or adfs. SSO_SAML_IDP_NAME=okta # Text displayed to user when they attempt to access Edge UI. 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. SSO_SAML_IDP_METADATA_URL=https://dev-343434.oktapreview.com/app/exkar20cl/sso/saml/metadata # Specifies to skip TLS validation for the URL specified # by SSO_SAML_IDP_METADATA_URL. Necessary if URL uses a self-signed cert. # Default value is "n". SSO_SAML_IDPMETAURL_SKIPSSLVALIDATION=n # SAML service provider key and cert from "Create the TLS keys and certificates" above. SSO_SAML_SERVICE_PROVIDER_KEY=/opt/apigee/customer/application/apigee-sso/saml/server.key SSO_SAML_SERVICE_PROVIDER_CERTIFICATE=/opt/apigee/customer/application/apigee-sso/saml/selfsigned.crt # The passphrase used when you created the SAML cert and key. # The section "Create the TLS keys and certificates" above removes the passphrase, # but this property is available if you require a passphrase. # SSO_SAML_SERVICE_PROVIDER_PASSWORD=samlSP123 # Must configure an SMTP server so Edge SSO can send emails to users. SKIP_SMTP=n SMTPHOST=smtp.example.com SMTPUSER=smtp@example.com # omit for no username SMTPPASSWORD=smtppwd # omit for no password SMTPSSL=n SMTPPORT=25 SMTPMAILFROM="My Company <myco@company.com>"
要安装 Edge SSO 模块,请执行以下操作:
- 登录 Management Server 节点。该节点应已安装 apigee-service,如安装 Edge apigee-setup 实用程序中所述。
请注意,您可以在其他节点上安装 Edge SSO。但是,该节点必须能够通过端口 8080 访问管理服务器。 - 安装并配置 apigee-sso:
> /opt/apigee/apigee-setup/bin/setup.sh -p sso -f configFile
其中 configFile 是上面显示的配置文件。 - 在 apigee-sso 模块中安装 apigee-ssoadminapi.sh 实用程序,用于管理管理员和机器用户:
/opt/apigee/apigee-service/bin/apigee-service apigee-ssoadminapi install - 退出 shell,然后重新登录,以将 apigee-ssoadminapi.sh 实用程序添加到您的路径。
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 Edge SSO:
- 将元数据 XML 的内容从 IDP 复制到边缘 SSO 节点上的文件中。例如,将 XML 复制到:
/opt/apigee/customer/application/apigee-sso/saml/metadata.xml - 将文件的所有权更改为 apigee:apigee:
> chown apigee:apigee /opt/apigee/customer/application/apigee-sso/saml/metadata.xml - 将 SSO_SAML_IDP_METADATA_URL 的值设置为绝对文件路径:
SSO_SAML_IDP_METADATA_URL
您必须在文件路径前面加上“SSO_SAML_IDP_METADATA_URL”,后跟根 (/) 的绝对路径。
