安裝FXOS機箱管理器的受信任證書

簡介

本檔案介紹如何產生CSR和安裝身分識別憑證，以便在FP 4100/9300系列裝置上與FXOS的機箱管理器搭配使用。

必要條件

需求

思科建議您瞭解以下主題：

• 從命令列配置Firepower可擴展作業系統(FXOS)
• 使用憑證簽署請求(CSR)
• 私鑰基礎架構(PKI)概念

採用元件

本文中的資訊係根據以下軟體和硬體版本：

• Firepower(FP)4100和9300系列硬體
• FXOS版本2.10

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路運作中，請確保您瞭解任何指令可能造成的影響。

背景資訊

初始配置後，將生成自簽名SSL證書，供機箱管理器Web應用程式使用。由於證書是自簽名的，因此客戶端瀏覽器不會自動信任該證書。新客戶端瀏覽器首次訪問機箱管理器Web介面時，瀏覽器會拋出與您的連線類似的SSL警告（非專用），並要求使用者在訪問機箱管理器之前接受證書。此過程允許安裝由受信任的證書頒發機構簽名的證書，這允許客戶端瀏覽器信任連線，並在沒有警告的情況下啟動Web介面。

設定

產生CSR

執行以下步驟以獲取包含裝置（允許客戶端瀏覽器正確識別伺服器）的IP地址或完全限定域名(FQDN)的證書：

• 建立金鑰環並選擇私鑰的模數大小。

此範例會建立金鑰大小為1024位元的金鑰環：

Firepower-chassis# scope security
Firepower-chassis /security # create keyring kr220
Firepower-chassis /security/keyring* # set modulus mod1024
Firepower-chassis /security/keyring* # commit-buffer

• 設定CSR欄位。可以只使用基本選項（如使用者名稱）來產生CSR。這也會提示輸入憑證要求密碼。

此示例建立並顯示一個證書請求，該請求帶有金鑰環的IPv4地址，帶有基本選項：

Firepower-chassis# scope security
Firepower-chassis /security # scope keyring kr220
Firepower-chassis /security/keyring # create certreq ip 192.168.200.123 subject-name sjc04Certificate request password: 
Confirm certificate request password:
Firepower-chassis /security/keyring* # commit-buffer

• 也可以使用更高級的選項來生成CSR，這些選項允許將區域設定和組織等資訊嵌入到證書中。

Firepower-chassis# scope security
Firepower-chassis /security # scope keyring kr220
Firepower-chassis /security/keyring # create certreq
Firepower-chassis /security/keyring/certreq* # set "ip 192.168.200.123"
Firepower-chassis /security/keyring/certreq* #  set subject-name "sjc04"
Firepower-chassis /security/keyring/certreq* # set country "US"
Firepower-chassis /security/keyring/certreq* # set dns "bg1-samc-15A"
Firepower-chassis /security/keyring/certreq* # set email "test@cisco.com"
Firepower-chassis /security/keyring/certreq* # set locality "new york city"
Firepower-chassis /security/keyring/certreq* # set org-name "Cisco Systems"
Firepower-chassis /security/keyring/certreq* # set org-unit-name "Testing"
Firepower-chassis /security/keyring/certreq* # set state "new york"
Firepower-chassis /security/keyring/certreq* # commit-buffer

• 匯出CSR以提供給您的證書頒發機構。複製以（包括）-----BEGIN CERTIFICATE REQUEST)-----以（包括）-----END CERTIFICATE REQUEST)結尾-----。

Firepower-chassis /security/keyring/certreq # show certreq
Certificate request subject name: sjc04

• 在Web瀏覽器的位址列中輸入https://<FQDN_or_IP>/，瀏覽到Firepower 機箱管理器，並驗證是否顯示新的受信任證書。

警告：瀏覽器還會根據位址列中的輸入來驗證證書的使用者名稱，因此，如果向完全限定的域名頒發證書，則必須在瀏覽器中通過這種方式訪問證書。如果通過IP地址訪問它，則即使使用受信任的證書，也會引發其他SSL錯誤（公用名無效）。
