安装和配置 Apigee SSO

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

  1. 创建密钥和证书
  2. 设置基本的 Apigee SSO 配置: 基础文件必须包含所有 SSO 配置通用的属性。
  3. 添加特定于 IDP 的配置属性:使用以下任一选项 配置文件中特定于 IDP 的配置属性块: <ph type="x-smartling-placeholder">
  4. 安装 Apigee SSO:安装 Apigee SSO 模块,并传递 将配置文件复制到安装程序中

后续几个部分将介绍其中每个步骤。

创建密钥和证书

本部分介绍如何创建可能适合您的自签名证书 但您应当使用由证书授权中心 (CA) 签署的证书 生产环境

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. 作为 sudo 用户,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

要创建无密码的密钥和自签名证书,以便与 IDP:

  1. 以 sudo 用户的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 -aes256 -out server.key 1024
  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. 将密钥和证书文件的所有者更改为“apigee”所有者:
    sudo chown apigee:apigee server.key
    sudo chown apigee:apigee selfsigned.crt

要在 Apigee SSO 模块上启用 TLS,请执行以下操作: 将 SSO_TOMCAT_PROFILE 设置为 SSL_TERMINATION 或 更改为 SSL_PROXY,则不能使用自签名证书。您必须生成 证书。请参阅为以下内容配置 Apigee 单点登录: HTTPS 访问

Apigee 单点登录配置设置

在安装 Apigee SSO 模块之前,您必须先定义配置文件。您将此 将配置文件复制到安装程序中。

SAML SSO 配置属性

如果您为 IDP 使用 SAML,请在 配置文件(在上文中进行了定义):

## 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.

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

# 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

如果您为 IDP 使用 LDAP 直接绑定,请使用以下配置块 属性,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

# Set true to allow users to login with non-email usernames
SSO_ALLOW_NON_EMAIL_USERNAME=false

LDAP 间接绑定配置属性

如果您为 IDP 使用 LDAP 间接绑定,请使用以下配置块 属性,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_SEARCH_FILTER=LDAP_search_filter

# 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

安装 Apigee SSO 模块

创建密钥并设置配置文件后,您就可以安装 Apigee SSO 模块。

要安装 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 已安装 apigee-service,如 安装 Edge apigee-setup 实用程序

    或者,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 是您在上面定义的配置文件。

  3. 安装用于管理管理员和机器的 apigee-ssoadminapi.sh 实用程序 “apigee-sso”模块的用户:
    /opt/apigee/apigee-service/bin/apigee-service apigee-ssoadminapi install
  4. 退出 shell,然后再次登录以添加 apigee-ssoadminapi.sh 实用性。

指定元数据文件(而非网址)

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 配置 Apigee 单点登录。

如需使用元数据文件(而不是网址)来配置 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 节点上的文件中。对于 请将 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加上“file://”前缀,后跟 根 (/)。
